8G I4 to V6 throttle body swap

[4g63lover]

Disclaimer: TGC and myself are not resposible for any damages that might occur as you follow this tutorial. Install at your own risk!

Ok, so I bought a V6 throttle body from Beam514 for my 4G64 and installed it through out last night and today.

I took the hood of my car because it is easier to work on something by the firewall without the hood than with it. You can take yours off or keep it works either way. I also removed my strut bar for easy installation.

Tools needed
Ratchet
Sockets:
14mm
12mm
10mm
8mm
7mm
7mm miniwrench
needle nose pliers
vice grip
an assortment of flathead and phillips screw driver.
and a dremel and cutting disc

First thing you have to remove is the Battery terminals the battery tie downs and battery. I have quick release terminals but I think the stock terminals are 8mm I believe and the battery tie downs are 10mm.

Unplug the MAF
http://i10.photobucket.com/albums/a103/4g63lover/baby%20g/IMG_3592.jpg
Remove the breather tube from the VC to the intake
http://i10.photobucket.com/albums/a103/4g63lover/baby%20g/IMG_3593.jpg
Now use your 10mm socket and loosen the clamp on the 90 degree coupler on the throttle body. Remove the 10mm ground bolt from the cam sensor that mounts the intake to the engine. Remove the intake.
http://i10.photobucket.com/albums/a103/4g63lover/baby%20g/IMG_3594.jpg
Intake removed. You can now see the throttle body
http://i10.photobucket.com/albums/a103/4g63lover/baby%20g/IMG_3595.jpg
Unhook the vacuum line from the cruise control. It might need a little force but make sure not to tug on it too hard.
http://i10.photobucket.com/albums/a103/4g63lover/baby%20g/IMG_3596.jpg
unplug the IAC.
http://i10.photobucket.com/albums/a103/4g63lover/baby%20g/IMG_3597.jpg

This is where it gets a little difficult. If you got big hand this is where you start cutting your shit up. lol

There are two major coolant lines you have to remove. one behind the throttle body that connects to the EGR and one that is under the throttle body that connects to the lower radiator hose inlet.

use either a flat head or phillips to loosen the clamps on the coolant line on the back of the throttle body. whichever works for you. and use a needle nose or a vice grip (Crescent) for the ones under the throttle body.

http://i10.photobucket.com/albums/a103/4g63lover/baby%20g/IMG_3601.jpg
Now, unplug the TPS (Throttle Position Sensor).
http://i10.photobucket.com/albums/a103/4g63lover/baby%20g/IMG_3603.jpg
It gets a little difficult here. I opted to remove the whole thing off of the TB because I couldnt get any leverage or my hands anywhere behind the connector to get the retaining clip off to get it off of the TPS. This is where the 7mm socket and miniwrench comes in.
http://i10.photobucket.com/albums/a103/4g63lover/baby%20g/IMG_3605.jpg
Use the socket on the drivers side screw and use the miniwrench for the passenger side screw. Wiggle the TPS out. BE CAREFUL.
Use a flathead to pop the retaining clip off of the connector to the TPS. Be careful to not fling it into space because the connector wont go back onto the TPS without that clip!
Heres the TPS off of the TB.
http://i10.photobucket.com/albums/a103/4g63lover/baby%20g/IMG_3606.jpg

Now moving onto the Throttle body. The Throttle Body has 4 bolts holding it onto the Intake manifold. You can see all four in this picture.
http://i10.photobucket.com/albums/a103/4g63lover/baby%20g/IMG_3607.jpg
Loosen all four bolts and remove the TB. Don't lose the metal gasket and dont forget to remove the lines on top of the TB. You can now remove the throttle cable. It'll take a little fiddling but I advice to remove the TB off of the intake manifold before removing the cable because it will give you enough slack to remove the cable without kinking it.

Side by side the intake side of the I4 TB and the V6 TB has no diffrence but the intake manifold side is significantly bigger. I'm not exactly sure on how big the I4 TB is but the V6 is a 60mm and its a noticeable difference when you're holding the two TB's side by side.
http://i10.photobucket.com/albums/a103/4g63lover/baby%20g/IMG_3608.jpg
V6 TB on top. I4 TB on bottom
http://i10.photobucket.com/albums/a103/4g63lover/baby%20g/IMG_3609.jpg

Before you bolt the TB onto the manifold, make sure to hook the throttle cable back on. Easier while you have slack than when its bolted to the manifold. Again, be careful and take your time fiddling with it to avoid kinking the cable. Once you got the cable on bolt the throttle body onto the manifold using the 12mm socket and ratchet.
http://i10.photobucket.com/albums/a103/4g63lover/baby%20g/IMG_3611.jpg

Hook the TPS Sensor back up. I was lucky enough to have had the V6 TPS sent to me by Beam so I didnt have to re-use the I4 TPS that I removed from the I4 TB. Remember that retaining clip? Lock the connector in with it. DONT LOSE IT!
http://i10.photobucket.com/albums/a103/4g63lover/baby%20g/IMG_3612.jpg
hook the IAC back up again. Once again I was lucky enough that Beam sent me the IAC and TPS so I didnt have to reuse the I4 one.
*NOTE: You need the V6 IAC for this to work properly!
http://i10.photobucket.com/albums/a103/4g63lover/baby%20g/IMG_3613.jpg
Hook all the lines back up. This will take a little bit of fiddling because the tubes they go on face a different way than the I4 TB so you will have to modify your lines. You're going to have to extend the lines that are located in the back of the TB and shorten the ones under. I cut one of the tubes from the I4 TB to connect to lines for the back. Thats where you need the dremel and cutting disc. Tighten the clamps.
http://i10.photobucket.com/albums/a103/4g63lover/baby%20g/IMG_3614.jpg
Put the intake back on and tighten the clamp with the 10mm.
http://i10.photobucket.com/albums/a103/4g63lover/baby%20g/IMG_3615.jpg
Now, put the battery, battery tie down, and battery terminals back in. Plug your MAF back in and start her up!!!
http://i10.photobucket.com/albums/a103/4g63lover/baby%20g/IMG_3616.jpg

Put your STB and hood back on and take her out for a spin.

Update: I drove the car today to go to work about an hour away and let me tell you the TB swap was one of the best mods i've done. Noticeable difference in response and the engine works at a lower RPM at a certain speed than the I4 TB.

[sponcar]

^ looks good man.....
well sowy if I sound like a noob in this question but yeah maybe I am cuz I dont know much about performance....
thats why I havent do anything on my engine.....
but Im trying to figure out what is this for...!!
its mean more fresh air on the engine???
or more gas on it????

thanks!!!!

[4g63lover]

it makes the engine breathe better. if you take the I4 TB off of the car you'll notice that the intake manifold side is significantly smaller than the outlet. so it makes the car more responsive and breathe easier.

[blue8g]

jigz how long did this take you?

[4g63lover]

hour and a half sunday night and about an hour this morning. going at a slow pace. lol. I was bored. lol.

[sponcar]

mmmm where did u get it..!!!....
and how much did u paid for it???
mmmmm seem pretty nice to me....
so tell us... how do u feel ure car now..???
and did u get better spin with the new mod...???

[beam514]

sponcar he bought it from me lol. It was my old TB that I didn't need after my 3.5L swap

and probably the most time consuming part of this tutorial is ripping the vacuum lines off the TB as they are probably REALLY stuck to the ports

I love it. My butt dyno says its a little quicker but its probably just more responsive than ever. I cant wait how it will be when its manual swapped. It feels great it was responsive before but its even more responsive now.

My vacuum lines actually came off rather easy. Putting the coolant lines back on took more time cuz the ports face different ways for the I4 compared to the V6.

I advice to buy a foot of flexible silicone line before you take your car apart

[SPD_FRK]

One thing to add is to bypass the coolant lines running to the throttle body. You can just loop those lines together and avoid running heated coolant through the throttle body, which as we know heated air is no good.

[4g63lover]

what do you do with the ports on the engine and the IM?

[SPD_FRK]

what do you do with the ports on the engine and the IM?
You can get some rubber caps (basically a vaccum cap I believe what they are called) and just cap off the inlet/outlet of the throttle body cooler fittings. Then, instead of routing to the tb you just run the line continuous to the other side with one hose section

[4g63lover]

huh. I wont run any issues doing that? I might go and try that to lower the intake temps.

[thestig]

i did it and havent had any trouble and noticed a steady performance peak instead of slowly decreasing due to the heat. so i say two thumbs up for the bypass. i might try the V6 tb swap though.

[SPD_FRK]

huh. I wont run any issues doing that? I might go and try that to lower the intake temps.
No you won't have any adverse effects from doing this other than unheated intake air temps. This is something a lot of other platforms do as well for the same reasons, those running forced induction will benefit greatly from this as well.

[4g63lover]

schweet.

[littlerick]

i think i learn atleast 1 thing new everyday on here lol i might start looking into it also

[sponcar]

wow i wanna do this on my car.... just need to find a TB from the v6 lol

[WhiteGalant]

Jigz you started a new trend for all the i4 guys on the site. lol

[SPD_FRK]

Hey, one thing I somehow forgot to mention for this is the Diamante Throttle Body. This was something commonly sought after by the V6 folks, but is a mere 3mm larger than the OEM TB. I posted a lot of the information on my intake link thats in my sig (may have to update that some more though).

If you are not afraid to tinker with the wiring of the difference in sensors the Diamante would honeslty suit the I$ folks much better for an upgrade rather than thos of us with the V6 platform.

[4g63lover]

Jigz you started a new trend for all the i4 guys on the site. lol

I try. lol. Seriously though, I owe it to Adrian. He gave me the idea. This is one of the best mods i've done to my car recently. Not to mention it's not an expensive mod at all.

SPD_FRK, wont you need to port the IM on the I4 to accomodate the Diamante TB I would assume?

[SPD_FRK]

That is something that may have to be done, but I will recheck some of the measurements on it and post back with what I find.

[qnz]

i didnt see you mention putting the gasket back on. You should get a new gasket to prevent vacuum leaks, and in the future, boost leaks ;)

[4g63lover]

ah. you're right. I did mention not to lose it though, hopefully it can be a common sense thing to put it back on. lol.

I'll replace the gasket when I bypass the coolant lines. I have no evident vacuum leaks at the moment.

[RedGalant2k1]

If memory serves the Diamante TB is as big as 70mm.

[M-Rod]

Hmm.. I heard 68mm somewhere for the Diamante TB. I may have to take mine off and measure it up. Maybe it even varies by year.

Diamante 3.5 with coolant line bypass sounds nice. Isnt the diamante a bolt on affair for the 6g72 so I believe we could use it

[4g63lover]

it is a bolt on affari but its a matter of matching the Intake manifold and throttle body to each other to get a consistent airflow.

Hmm.. I heard 68mm somewhere for the Diamante TB. I may have to take mine off and measure it up. Maybe it even varies by year.
M-Rod is dead on, the Diamante TB is only 3mm larger in bore than the stock 6G72 TB, if you are doing a bigger bore TB on the V6 platform do it right the first time and find an Infiniti Q45 90mm TB.

[4g63lover]

Whoa, the stock 6G72 is 65mm? I coulda sworn it was only 60mm.

[Poison457]

ok so i did this swap, looped the coolant lines and used the v6 tps sensor and gasket, i'm having a major problem when i start the car it revs up to around 4k then bounces back and forth from 2k to 2.5k "i have a 4g64 btw", i thought the TPS sensor was bad so i went back to my old one same exact problem i adjusted the throttle cable back to about where it was with the I4 throttle body made no difference "because the cable was way to tight at first butterfly was open a good portion".

So now i'm stuck the car runs isn't throwing any codes but rev's like crazy, trying to adjust the tps sensor just makes it rev higher but constant, realy need some help here heh.

[4g63lover]

have you turned the idle screw all the way to close?

Have you checked the IAC? My idle revs up to 2300-2500 RPM at first start up but after a couple minutes it goes down to 700-800 RPM. But I did throw an IAC code though...

The position of the throttle cable for the V6 TB compared to the I4 is in the EXACT same position, so that shouldn't be a problem. As long as you can feel slack move the cable in and out you should be okay. The I4 TB is the same.

My issue didnt only happen after I looped the lines. It also occured when I had the coolant lines running to the TB.

I'm 98% sure it's the IAC for me, because it would've thrown a different code otherwise. Considering everything else is copecetic, which seems to be the issue since it drops back down to normal idling speed once warmed up.

So check the IAC for sure.

BTW, I am throwing an IAC code but the light isn't on, so make sure to check it anyway.

[sponcar]

so can we use the TB from the diamante on our 4g64..??? or not???
just wondering cuz I found many diamate on the local junk yard....

[Poison457]

4g63lover,
in your tut you said "i was lucky to have the IAC to" lucky is definitely the word for it heh, the new style iac run's on vacuum the V6 throttle body has a larger bore IAC port than the I4 IAC port by i'd guesstimate 2-3mm give or take .5mm therefore using the I4 IAC is not possible, you have to use the V6 IAC so you get the proper vacuum to the IAC sensor and get the correct idle speed, how i came to this conclusion.

after tinkering with it all night long adjusting throttle cable tension, swapping out the TPS sensor's, adjusting the TPS sensor position, even pulling out a multimeter and adjusting per the service manual, i finally got it to idle steady at 3.5k rpms, car ran fine no codes 100% drive-able, if you call the idle speed in drive 1.5k rpms drivable, so i finally said phooye and was switching back to my stock throttle body.

I decided to take a close look at all the small differences between the two and that's when i noticed the IAC port, it's significantly larger on the V6 than the I4 "significantly for vacuum purposes anyways". finished putting on the I4 throttle body car runes perfect. so my conclusion is you need the IAC from the V6 to make this swap, i don't have the means to get one right now and test the theory but i'll update it about a week and let everyone know.

Poison

Edit
to further this theory i pulled the part #'s for the IAC's
I4 acdelco 2171827 OEM 89053340
v6 acdelco 2171821 OEM 89053334
so looks like i'll be heading back the junkyard in a few days trying to find an IAC for a v6

Edit 2
according to the service manual the I4 throttle body is 54mm, and the v6 is 60mm i'm going to bore out the intake manifold to match the v6 throttle body when i get the new IAC and will post up pics and info on performance

[4g63lover]

my IAC is for the V6.

Thats some good info poison.

[M-Rod]

so can we use the TB from the diamante on our 4g64..??? or not???
just wondering cuz I found many diamate on the local junk yard....

Yes, as long as you use the throttle body from the 6G74 engine. Just make sure you get the pigtail harness from the IAC.

[sponcar]

^ok ok thanks guys...

[galantofva]

I just got my v6 throttle body from a junk motor at work today. Does bypassing the coolant cause a CEL? Also what size line and how much do I need to do the bypass?

[SPD_FRK]

There are no CEL's that come with doing the bypass. You need I believe about 8-10" of 1/4" ID hose, and some clamps to do it.

[sponcar]

Yes, as long as you use the throttle body from the 6G74 engine. Just make sure you get the pigtail harness from the IAC.

btw those are the only things that I need for this swap???
sorry if I sound like a noob... but me dont know too much about perfomance...

[galantofva]

Poison457 I am having the exact same problem. Only difference is mine was reving to 3k steady. I hit the gas and took it to 4k and then it started bouncing between 2500 and 3k and holds steady at 1500 at idle in drive. I will try to get a v6 IAC first thing in the morning and I will let you know if that helped.

Becuase the Diamante TB is different, as well as the IAC sensor plug you will neede to obtain a wiring schematic for the Diamante TB stuff. I was going to perform the Diamante Intake manifold and TB swap for my V6, but given the sensor differencse, and the minimal 3mm gain in size over stock I did not pursue the details further.

Ivory8g now has my Diamante TB and we are both trying to obtain the needed information in order to be certain the IAC pigtails are wired up correctly, unless others have the information available at this time...

[Ivory8g]

yeah that wiring diagram is a pain to obtain. we might have to use your resources Blackheart.

[stvn_mj]

Keeps us posted that's something Im interested in learning.

[Ivory8g]

did a lot of reading on c3g and i might just balls to the wall and try something....

[4g63lover]

why is everyone having issues with idle? are you guys letting it warm up at all when testing? Cuz mine goes up to 2300 then drops to 800 (normal idle) after about 3-5 mins. and nothing but responsiveness while driving. IDK why you guys are having issues. Did you guys clean it beforehand? Adrian did clean the TB I got before shipping it to me so maybe thats causing an issue. but mine is fine as long as I let it warm up...

just so you know,
during my swap I ended up having to use the 6G74 IAC and the corresponding plug for it. I ended up just snipping off the old 6G72 plug (on the car's side of the harness) and wiring up the 6G74 plug (car side of the diamante) that came with my engine by matching up the pins. No codes or anything and I passed SMOG. I dunno if that answers your question or not

[Ivory8g]

thats really what I was talking about when I was saying im just going to balls to the wall and just do it. i am gonna snip the harness and wire it in by the pin. its what the 3g guys seem to have done because they said the wires were all the same just different connectors. only thing is i take everything from that place with a grain of salt. so thats why i was waiting on the wiring schematics. did you use your stock tps or wire in the diamante tps according to the pins as well?

[beam514]

I used the Diamante TPS. It plugged right into the car's harness

also, the couple minutes of higher idling was and still is normal for me

Now that I have the 6g72 IAC its doing fine. Drove around for a little this morning, only issue was I had to mess with the idle adjustment screw till I got the idle where I wanted it.

I just cut off the old pigtail wire by wire, and soldered the new one for the 6G74 in the corresponding wire locations and everything works perfect. It was 6 wires in total. IMO, it was worth the 15 minutes it took to change the plug. Plus the TPS plug was a direct fit and everything is fully operational.

[Ivory8g]

sick! looks like i will be swapping it today then since this is prolly the last day in the 70's we are going to see within the next week +

Never thought it would be as easy as just swapping the pins out. I just never found the benefit and time worth while for a small 3mm bore size gain over the stock TB for the V6 platform. The only thing I can justify being "worthy" of claiming a big bore TB swap for us would be jumping on a Q45 90mm TB unit. The 4 cyl folks are truely the ones who benefit from the Diamante TB though...

mmm did you reset your ecu after puting in the new iac? like with anything doing with air modification's you should always reset your ECU so it can "relearn" the A/F ratio, did you get your iac from the junkyard, could it be bad? it's been raining cats and dogs here in texas so havn't gotten out to junk yards yet to get one, i know where there is one and the car is complete with a sealed hood so the one i get should be good gonna try to get out there tommorow if the weather is good i'll let you know if i run in to the same problem

[galantofva]

I got mine from a junk motor at work. The IAC is fine. How do I reset the ECU? With a scan tool or just pull the negative terminal?? BTW my car has been DRINKING gas since this mod.

haha its not the car bro its you. lol.

On the serious, my gas mileage got better on the highway cuz RPM sits at 2700 instead of 3000 at 70mph. I havent driven in the city much to tell a difference there. And quite honestly, I am having trouble keeping my foot out of it cuz I LOVEEEE the exhaust note now! I feel like I'm sixteen again!!! (Wow, that sounded really effin' gheyyyy)

It could very well just be me. I have had trouble keeping off it also. I too noticed a change in my exhaust. It sounds alot deeper than it used too. I also switched to mid grade to see if it would make any difference with all that extra air. Havent really noticed too much. BTW what size is the v6 compared to the I4?

I know the V6 is 60mm not sure about how big the I4 TB is.

and yeah I've been running 93 since I swapped the motor and the SES blinks at me if I go down a grade. wierd right? lol.

My exhaust went from Honda to nice deep tone.

[galantofva]

did you really notice anything after switching to 93?

[4g63lover]

well, considering I switched to 93 as soon as we got the new motor running, its really hard to compare. Although, back when my dad drove the car and mindlessly put 89 in it the car got more sluggish and less responsive. Then as I said, I accidentally put 87 in it and the SES flashed and blinked at me. I thought it was wierd because I've never heard of that happen, but I guess once it gets used to a certain octane it LOVES that octane.

[SPD_FRK]

I know the V6 is 60mm not sure about how big the I4 TB is.


The V6 TB is a 65mm, the Diamante is a 68mm..at least those were the measurements I got from a pair of calipers anyways

[galantofva]

Thanks

[KaziKai]

anyone have a V6 TB laying around and would like to sell it to me? PM me!

[galantofva]

^^I may be able to get you one frommy job, Ill let you know as soon as I find out. To every one else I "reset" the ECU and turned the idle back up a little and after a week of driving I havent gotten another SES light and it seems to do alot better. Def drinks less gas now that I got used to not trying haul ass everywhere........ Its just so easy now.

[4g63lover]

I did the same and the IAC code disappeared completely.

[galantofva]

Well I made it 4 days with no SES the first time, and almost two weeks this time. However, it is back again, and its annoying as hell. I gotta try to get my hands on a new IAC.

[galantofva]

Hey I have a couple of extra v6 IAC motors that I can let go for cheap. If anybody needs one PM me for info.

[jonguyen11]

can someone show me what the IAC looks like?

[stvn_mj]

If you go to the first page there is a pic that says, "unplug the IAC." If you look at the pic thats the IAC.

[davis.ryan23]

what kind of car did u get the throttle body off of? Where you talking about a bmw? If so what year?

[4g63lover]

it comes off of a V6 8G Galant.

[galant4life]

ok , so i finally got my hands on a complete throttle with sensor off of a v6 for my 01 4cyl,,,,now, do i put a gaskit for a 4 cyl or a v6 with this swap?
i have a 4 cyl 01 8g,
thanks

[Galant Evolution]

Would this throttle body work with a TB spacer as well? do i get a v6 application or I4 TB spacer?

[qnz]

ran into 2 small issues doing the swap today but was able to complete the install. total time took about 2 hrs.

Im using an Evo8 Fuel rail which is the reason why I had these 2 issues.

When I tried to route the coolant thru the V6 TB, one of the passages is blocked by the fuel feed line. I just improvised and did the coolant bypass like Jigz and other people reccomended.
http://i203.photobucket.com/albums/aa170/qnzaaron/PICT3659-1.jpg
The wires for the IAC are touching my fuel feed line, also, because I am using a evo8 fuel rail. I just put some wireloom around the wires for now. I'll inspect them from time to time to see if they are melting or getting chafed.
http://i203.photobucket.com/albums/aa170/qnzaaron/PICT3658.jpg

[stvn_mj]

Are you happy with the results? I did it last week and I like it so far.

[qnz]

the throttle response is an improvement. Hard to tell how much hp it gains because my turbo also adds "torque".

I only swapped my TB because my old one had boost leaks. I added turbo shaft seals and a new gasket.

[stvn_mj]

I had to swap mine because of the trouble I was having with my tps and iac. Does yours idle high at first then after a few minutes comes back down?

[qnz]

mine still idles high actually. I turned the idle screw all the way down and im still around 950 rpm. I wonder if adjusting the TPS would get it to idle lower?

On initial startup, it does shoot to 2000 but it came back down to 1000 only after a few seconds, not minutes.

[stvn_mj]

Not sure about adjusting the tps. But I probably have to mess with the idle to get it right. I can't tell how high mine shoots up on startup because something happened to my tach so my needle is off a little. But now I noticed that after like a minute it goes down but like the first few days it took my like 2 1/2 minutes to go back down.

[4g63lover]

Mine always shoots up to 2k+ at first especially when it's cold. It drops to around 800 after a few minutes. As for the fuel line clearance, Aaron, I didnt run into the IAC wires rubbing, it was probably because you are using an EVO rail.

[Joshua42007]

I had the same exact problem with mine, mainly in the mornings at a cold start, and also in traffic. I swapped to the v6 TB and it happen to have fixed all my problems. The car now idles smoothly.

[Joshua42007]

Thanks alot for the tutorial, it helped out a whole lot. Very easy to do, only thing is i have some big ass hands.

[qnz]

Thanks alot for the tutorial, it helped out a whole lot. Very easy to do, only thing is i have some big ass hands.

ya no kidding. the back of my hand is all red with welts. I replaced the clamps with worm clamps

[Honkasena]

i had to pigtail my IAC for the V6 IAC...it idles fine on its own but i can rev it past 2500 sittin or drive it pat 1500 k...it "bobs" and wants to stall...shoul i chang my TPS to the V6 one? HEEEEELPPPPPP!!!!

[4g63lover]

What do you mean by "pigtail"? did you rewire the I4 pigtail for the V6 IAC? if so, why? the I4 pigtail work on the V6 IAC.

[qnz]

the tps for the v6 and the i4 are the same part numbers so there wont be a difference. The IAC pigtail for the i4 should have clipped right into the v6 IAC sensor

[Honkasena]

i figured it out on my own...the sensor of the diamante IAC i grabbed was different, not plug n play...it has 2 bolts/screws holdin it on and is significantly bigger, whereas the 2.4/3.0 has 3 bolts/screws and is kinda small...also i used the TPS from the i4 like the tutorial said which was big no no....the ECU wouldnt let me go past 2K rpm's...my ECU was like "what the #@&! is all this air?"...lol...just an fyi for everyone who wants to do a TB diamante swap....make sure u grab the IAC connector from the diamante's wiring harness, pigtail it, match the IAC up wire-for-wire, and keep both sensors from the diamante TB on the TB when u swap it...that will make it run correctly...jus adjust the idle screw at operating temperature and viola....best mod done so far....doing the coolant bypass tomorrow...YAAAAAY!!! lol...

[Mike_ODell]

sweet ass! I just saw two diamante tb there today and was like nah...i cant use it.....im headed to the junkyard tomorrow morning. I know what Im grabbing.

[bigvic]

so to reset the com, you can just use the ol fashion negative terminal unhook and leave it off for bout 10 sec and hook it back on right?

[keith6110]

so to reset the com, you can just use the ol fashion negative terminal unhook and leave it off for bout 10 sec and hook it back on right?

Works for me! I think maybe its 15 mins? It makes the service engine soon disappear for a bit tho. I'm guessing it does a full reset.

[bigvic]

Works for me! I think maybe its $15 mins? It makes the service engine soon disappear for a bit tho. I'm guessing it does a full reset.

o ok thx again man lol

[Sphinx]

Im really interested in this. Whats a fair price for a Diamante TB? What years of Diamante are fair game? Anyone have follow ups or more info?
Thanks TGC!!

Thanks TGC!!

Sphinx

better yet could that get updated to the first post as far as what all is needed for the Diamante TB (IAC, etc....) to work correctly

[Sphinx]

Im settling for a plug-n-play V6 TB swap and not bummed one bit LOL. Adding a Ingen Air Intake and fresh plugs and wires. That will be it for my Go-Fast parts the rest are Go-Stop and Go-Turn parts! LOL

Sphinx

[Conjee]

Just Installed Diamante Throttle Body on my 4G64 with coolant bypass. Soldered the IAC wires, I didn't have a pigtail. Response is so much better and acceleration is smoother. Exhaust sounds better too. Only problem is that my Cruise Control doesn't work anymore and I am getting a SES P0401...wonder why, anyone else get this?

[Sphinx]

Sorry can't help but I am eagerly waiting from my V6 TB! I installed my k&n typhoon and it let the G spin up to RPM much quicker. Running a slush box with 157k every little bit helps.
What TB did you have before the Diamante? Stock?

S

[Conjee]

Yeah I had the stock I4 TB. Car seems fine, no symptoms. I erased code, but it came back.

[Galantman03]

^Did you hook up the vaccum lines in the right way? you can reverse them. I swapped and no codes, and my cruise worked great lol, till i did the 5 speed swap...

[Conjee]

I hooked the two vacuum lines exactly how the I4 TB was connected. I will try reversing them, then erase code. Will update.

Update: Tubing I used were bigger causing a leak which resulted in SES light and no cruise. Used a smaller diameter vacuum tube, SES light went away and cruise is working.

[Galantfan88]

Hey guys sorry to bring up an old thread, but something came across my mind about swapping TB. I read the entire thread about how you can swap the 6g72 and the 6g74 TB on the 4g64 TB...But what about an 03 Outlander Intake manifold??? Would this be the same with an outlander TB?

I believe the Outlander TB is the same size as the v6 G, but would a 6g74 fit onto the Outlander manifold? Not sure if anybody has done this yet but if so please let me know and what wiring I would have to come across. Thanks guys

[mrg7243]

yes the outlander tb bolt pattern and galant is the same, also the galant will fit on an evo monifold

[Galantfan88]

yes the outlander tb bolt pattern and galant is the same, also the galant will fit on an evo monifold

I know that, what Im asking or saying is that I have an Outlander intake manifold and would like to know if a 6g74 TB would work on the Outlander TB?

[WhiteGalant]

, also the galant will fit on an evo monifold

I dont think so...

[Galantfan88]

also if anybody is selling a v6 TB for dirt cheap let me know, thinking of doing this to the motor thats in the car right now just for shits and gigs.

[Sphinx]

Just got my V6 TB and am really looking forward to installing it. Ill report here how it goes.

S

[Galantfan88]

Anybody know if the 6g74 TB will work for an outlander manifold??? Imma try to see if I can compair them but if anybody knows...please let me know.

[mrg7243]

I dont think so...

logically it should, since the evo throttle body gasket and the v6 throttle body gasket are teh same part

[beam514]

Anybody know if the 6g74 TB will work for an outlander manifold??? Imma try to see if I can compair them but if anybody knows...please let me know.

why wouldn't it be able to bolt up? The 6G74 TB bolts up to the 6G72 manifold, and the 6G72 TB bolts up to the 4G64 manifold. Also, the 4G64 TB bolts to the Outlander manifold, therefore by like 1 million transitive properties, the 6G74 TB should be able to bolt up to the Outlander manifold.

[Galantfan88]

why wouldn't it be able to bolt up? The 6G74 TB bolts up to the 6G72 manifold, and the 6G72 TB bolts up to the 4G64 manifold. Also, the 4G64 TB bolts to the Outlander manifold, therefore by like 1 million transitive properties, the 6G74 TB should be able to bolt up to the Outlander manifold.

Awesome, just double checking. Thank you very much

[PrityG-lant03]

Can u put together a V6 throttle body and an 03 outlander intake manifold???

[mrg7243]

I am pretty sure you can,

[Isaurio]

i'm going to try that swap soon. I have an oulander mani, just got an tb from the diamante 65mm from galantfan88. Let see how the swap comes out. Just missing the mani and tb gaskets to complete parts.

[mrg7243]

if the 4 cyl one bolts up to it then the v6, kia, and evo one will

So baised upon gasket pattern this means that the Throttle body flanges are all the same bolt pattern from alllll of the cars which is great. Now the throttle body bolting up is 99% garanteed, but whether the throttle cable, or anything else connects i could not tell you.

[Rach3T8G]

ok so i did the V6TB swap 2day & im having a problem. after putting it on i started the G & it revved to 4k then went down to 1.5k which is normal since i had the battery disconnected but it sounded like a Carburated vehicle so i drove it for maybe 20 mins & now the idle bounces from 2k-3k & vice versa im thinking its the IAC that needs to be replaced maybe but if any1 has thoughts on what it could be let me know i'd appreciate it thanx

[4g63lover]

did you hook the maf back up?

[Rach3T8G]

yea i made sure evrything was connected back before i drove it for 20 mins

[4g63lover]

if it was a used tb its possible it has a bad IAC.

[Rach3T8G]

yea its used & im thinkin it is the IAC but i wanna make sure it is definitely the IAC first

[4g63lover]

is it throwing a code? Hook it up to the scanner, CEL or not if the IAC is bad the scanner will pick it up.

Clean the TB as well, and did you use a V6 TB gasket. That could cause the fluctutating idle.

[Rach3T8G]

Yea as soon as i got home the CEL came on. im gonna hook up the scanner later on tonight to see & no i usin the 4Cyl gasket temporarily. I called for the V6 gasket & i have to wait till it comes from the factory

[Rach3T8G]

ok so i went to autozone & i got the right gasket. i also had them scan the G & im getting multiple cylinder misfire & idk how b/c i just changed the plugs & wires but im gonna check evrything over

[4g63lover]

do you have the wires in the right order. Make sure you got it in the right order, if it's firing incorrectly it will make it sound like a carbed motor.

[Rach3T8G]

the wires are in the right order i dnt understand why it would be misfirin. it was fine b4 the swap

[Rach3T8G]

im gonna use my friends code scanner later tonight to see for myself

[4g63lover]

bad gas?

[Rach3T8G]

that is a possibility maybe the coil packs are bad idk

[Rach3T8G]

scanned it myself & it is in fact multiple misfire PO300 dnt think its bad gas either

[Rach3T8G]

so i figured out the problem turns out it was in faCt misfirein, ddnt kno there were plugs under the Coil paCCs (feel kinda stupid) & both the Coil paCCs & the plugs under em' were submerged in oil :(

[Rach3T8G]

ok so i changed all the spark plugs & coil packs & found the real problem my IM cracked right where the TB bolts up so now im looking for a 03' outlander IM w/ all the sensors needed to do the swap or im getting a new car

[HungarianHunter]

I know this thread has been dead for a little while, but I have a question.

Does anyone have pictures on how to do the bypass?

EDIT:

I was looking at the picture, and are the two bottom inlets/outlets the coolant lines? So would these just need to be capped, and a line ran between where those two originate?

If that makes sense...

Thanks

[M-Rod]

yes, the heater lines are to be connected to each other, bypassing the tb.

[P'NOYcaL]

the tps for the v6 and the i4 are the same part numbers so there wont be a difference. The IAC pigtail for the i4 should have clipped right into the v6 IAC sensor

another revival thread :109:

im a little confuse with this mod. As far as what i understand from jigz, its better to have the tps and IAC already attach with the TB WITHOUT the pigtail(i believe is the stock wiring harness of the original car). And if the stock wiring harness of 4G64 should work and plugged right in...whats all the pigtail, soldering needed etc.. is about? sorry for the confusion. Btw im talking about 6g72 tb here (what im about to do)

im planning on doing this after the long winter season

[Rach3T8G]

theres no soldering needed for the 6G72 TB. the only thing you need really is the IAC. You can use the TPS from the 4G64 TB.

[P'NOYcaL]

oh nice. so basically all i have to do is plug-and-play if the tb comes wit the TPS and IAC using my stock harness. Plus bypassing the two lines at the bottom.

i just hope i wont get any code or light on the dash. wish me luck!

[Rach3T8G]

your bypassing the coolant lines? & good luck with the swap

[Ivory8g]

I included the tps and the iac on the tb :)

[Isaurio]

I will recommend for the winter not to bypass the coolant lines, leave it for the summer.
Also disconnect battery before you do the swap. This will make the ECU re-learn the idle speed on the IAC. Let it idle for 20 min. Maybe you will have to re-adjust the TPS and idle screw to get to the right idle. Between 700-800 RPM

[P'NOYcaL]

alright thanks for all the positivities!

[P'NOYcaL]

i got the TB today! woot!!! thanks ivory8g for quick response!

oh btw one more thing..since its 3.0L and the diameter is much bigger do i need to replace my 4cyl CAI to 6cyl or 3.0L air intake?

[Ivory8g]

since you have a coupler and not the stock box i think the coupler should have enough play to fit the tb. And your welcome!!
Dont forget to hit me up on my trade rating! :)

[P'NOYcaL]

i just ordered my tb gasket...after leaving pepboys i realize...i ordered the tb 4cyl gasket and i completely forgot im working on a v6 tb :( i dont know if it ever matter? im hoping theyre the same gasket

[Galantman03]

^um i guess i never bothered with putting the v6 gasket on... nothing out of the ordinary happened.... i say give it a shot but it worked for me lol

[Rach3T8G]

I used the V6 gasket wit mine i think it doess make a slight difference

[P'NOYcaL]

^um i guess i never bothered with putting the v6 gasket on... nothing out of the ordinary happened.... i say give it a shot but it worked for me lol

u installed yours already?:104:

well i mean if the v6 tb is just bolt on and has the same bolt pattern as I4 im thinking it should work..lets hope.

[Rach3T8G]

It works but I'd jus get the V6 gasket w/ it

[Night_neo2000]

Hey, kinda new but have done alot of reading. I just bought my first 03 galant 2.4L a gun metal grey color. I am interested in the v6 tb swap and have found one at a local junk yard in ohio. My question is, if i were to install a tb spacer, with or w/o the gains/losses would it be for the 4cyl or 6cyl?, wondering if anyone else has tried this before. sorry for being new again, im used to toyota's but have now been converted to mitsu. thnx for your time guys

[mrg7243]

Dont get a Tb spacer. It is a waste of money. The car is already torquey enough.

[Night_neo2000]

ok so i got the tb today and installed. was easier than i thought and looked. i had to adjust the position sensor a little bit for lower idle, but wont idle below about 950. drives fine, and very touchy. i have two problems?, maybe. first one is when im coming to a stop at 10mph it kicks down/or forward to downshift im assuming, its more annoying than anything else, and second is when i put it in neutral "automatic" it revs high at 1600rpms.normal drive gear idles at 1200rpms and mrg7243 yeah the throttle body spacer isn't going to happen. i was just curious.

[Redhaze]

Check your intake and maf. that might solve the kicking issue you might have a leak somewhere.

[Isaurio]

Double check the tps. Adjust it.

[Night_neo2000]

ok, so i ended up putting the i4 tps back on and it idles fine, i couldnt get the v6 one to adjust right, im just assuming its bad since it was from the junk yard? idk... in order to get that tps off easily i took one of the coil packs in front of it off, and think i didnt tighten it down again good. cause while driving the rpm's fluxuate about 500. ill have to look at it tommorrow when i get off work, but im hoping thats what it is, ill also leave my battery unhooked while working this double tonight and see if it resets anything.

[Exhaust power]

Does anybody know or could find a female connector (i4 iac style) so i can connect both pig tails on the engine side to a 6g74 pig tail? it would save me the concern of cutting up my wires in the engine bay.

[Armageddon Sunset]

the 72 TB in the galant is it the same TB out of a 91-93 n/a 3kGT?

nvm looking like the 3kgt is around 70mm, found one sized at 75mm. anyways does anyone know if these are usable on the 4cyl, and what would be needed? I would guess it would be about the same work as installing the 74 TB

[JDyal]

Wow I know this is old but I'm so impressed, I can't wait to do this and also paint the engine head like you did xD

[mrg7243]

Why did you bump a thread just to say that?

[Redhaze]

Lol I thought the same thing when I saw it earlier but just ignored it

Sent from your Mommas House using pimpahoe

[djaltamira]

Sorry for bringing back such an old thread, but did anyone who has done this swap ever got a P0507 code? Everything seemed to be running normal when i installed it, after my car warms up it idles at ~800RPM on gear and ~1000RPM while on park. Then a week later since the swap, this code pops up.

Here's the definition of the code P0507:
Idle control system RPM higher than expected
Probable cause
1. Large vacuum leak on engine
2. Throttle body condition - Dirty(i'm pretty sure it can't be this since i cleaned the throttle body before installing it with CRC Throttle Body Cleaner and removed the IAC motor and TPS before doing so)
3. Faulty IAC valve/Throttle Body (Kind of thinking this could be causing this issue, since i got my throttle body assembly from a junkyard)

Thanks in advance! hopefully i could get some help on this

Are you sure you put the gasket is on correctly? When I put the 6g72 TB on my Eclipse I had a bad vac leak and I could hear it, I had to flip the gasket 180 degrees and the leak and noise went away.

[djaltamira]

I'm pretty sure i did that because, the holes only matched up with the bolts when i had the gasket flipped, as you said, 180°. But i'll check again tomorrow

[djaltamira]

I didn't find any vacuum leaks, but could using the i4 Throttle Position Sensor cause this issue? help please

Just read that the TPS for th i4 and v6 are the same. What else could cause the code PO507?

[tamim13]

You should use the IAC from the v6 and are you sure the TPS is the same for 4cyl and v6? When I swapped, I had a similar code (it looks familiar, but I didn't write it down), but it was because the gasket was the wrong way on. I later on swapped it with a v6 gasket anyway.

[djaltamira]

I do have the V6 IAC installed and used a V6 gasket and yeah, i re-read this whole post and someone said that the V6 and I4 TPS had the same part number. Which way exactly is the right way to install the gasket? I just adjusted my TPS and cleared the code for now, but if the code comes back(hopefully it doesn't) i'll take a pic of how i installed the gasket

One:
You need evoscan to see where your tps % is at. It should be around 12.5-13.3%. Any higher idle will go up and pcm will thinks is not idling.

Two. Do a leak test around the tb. Some times gasket could be install wrong.

3. Pcm needs to re-learn iac trims. You need to reset pcm "disconnect batt for 5 min with headlight ON to reset fuel trims. Let it idle for 30 min no rev, take it for a nice drive 30 min or so. And rev then let go of the gas so iac could adjust it self

I don't have any issues with mine but I didn't do this when I replaced my t/b, will have to try this method for the pcm re-learn. Thanks Isario

My car stumbled a lot when the gasket was installed incorrectly. What I noticed was, on the intake side, there were three little holes just on the top and if the gasket isn't installed right, it doesn't cover the holes properly, and causes the roughness.

[djaltamira]

coconut, did you get your throttle body from a junk yard? or did you pull it from a working galant?

tamim13, did the code P0507 ever come up for you? and how long after your first install of the throttle body did you decide to check if the gasket lined up correctly? because for me i was code for about a week after the swap and everything was running fine i think

For everyone that did this swap, could you share how much you are idling if it changed at all? I don't remember how much i was idling on park and on gear before but now i'm at about 1000RPM on park and about 800RPM on gear after warming up the engine. Does this sound right? or is it too high like the code says? This is really bothering because my car is due for another inspection soon. Thanks everyone for the help so far, hopefully i would be able to solve this issue without having to go back to the i4 throttle body.

[coconut]

Got mine fron the J/Y and it came off a v6 galant.i cleaned mine before i installed it, new gasket installed also for the v6 not for i4.Mine did idle high,made some minor adjustment with the idle screw.Idled at 800rpm in drive with the auto trans but im manual swapped now and its at 800rpm.Did you make sure the vacuum lines on top of the throttle body are in the right spot?Dont know if that would make a diffrence but just throwing it out there.

[tamim13]

I don't remember the code that I got, but the idle was not too fast, it was stumbling a lot, like the engine was about to die, that's how we figured it was a leak. It was right after the install and first time I started it up. After correcting the gasket, and starting up cold, my RPM would be about 1.5K and then drop to about 1K - 900. After driving around it would come down to about 750-800. I had to adjust the idle screw all the way down to the minimum. Also had to disconnect the battery for the whole process of swapping the TB, so the system does have to relearn the idle. I also changed the coolant lines to the v6 ones, the i4 does not fit on the new TB.

^^^ what he said

[djaltamira]

I've been code free for the past week, thanks for the help guys! All I did was adjist the BISS Screw so that my idle on park was between 800-900RPM and the code just went away. Didn't need to clear it or reset my ecu. Just updating for future reference, thanks again!

I know this is kind of old, but, I'm in the process of doing this retrofit, (Outlander Manifold with Galant V6 throttle on a I4) and want to gather all the important info; So, my question: disconnect the battery with the lights "ON"? Also, is there an easy way to adjust the TPS? Thanks for your replies.

Evoscan or any data log that reads tps % will do or just dont touch the tps position from the factory location.

[PR8GG]

yes, I end up changing all the sensors, from MDP, IFS and the TPS; finally the problem was a crack in the manifold, but I still have an issue, I am still getting a code, P0401 "Exhaust Gas Re-circulation Flow Insufficient" and I remove all the EGR system, cleaned and re installed; even changed the EGR Valve; still got the code; the car idles low then cold, and when I and driving, if I push the gas pedal hard, it acts as if it's not getting gas, I let go a little the pedal and it is back to normal. I being clearing the codes with my scanner but it's not an evoscan, it's an Actron CP9580A. This is why I as about the clearing method you mention, disconnecting the batt with the lights ON? Any advise will be welcome.

[musty_hustla]

I remember pitching this swap to my wife and she wasn't having it! LOL

The galant was her daily driver.

[CHICAGO_ONE]

Match it with an intake and she'll love the sound, lol.

[Freshasfuck8g]

Sorry for bringing up an old post but will the V6 eclipse TB work also?

[Black8GV6]

Did you READ the entire thread?














































































































































also you are clearly new to the platform but the 3G and 8G is basicly the same car so alot of crap is interchangable

[Freshasfuck8g]

Yeah thats what i figured i just wanted to make sure. Ive had my car for 6 years now but i havent done any engine mods to it. Mine is mostly cosmetics as im more into making it look good
