TB options

[spdracr]

Let me make sure I got this right. Stock 4g64 TPS and IAC work on the evo TB and we don't need the evo sensors??

[Silvertune]

The IAC works, not the TPS and the sensors are different. Your stock TPS pigtail plugs in but it needs repinning, just follow the directions in the link I posted and you'll be running Evo hardware.

[spdracr]

I have no time at the moment to read that but I definitely will when I have some free time. I'm just trying to figure out if I need to buy the evo sensors since I bought a bare TB.

[Silvertune]

You'll need the Evo TPS at the very least, only thing I know about the IAC is that its plug and play, whether or not the IAC motors themselves are interchangeable I couldn't tell you.

I've been running my stock 4g64 TPS on my evo throttle body, no problems yet

guess im lucky my 6g has a stock 60mm TB

And u r using an evo IAC??

[duh2150]

Galant Tps and iac, they are different part numbers the tps between the 2, I didn't see why id need to buy a 100 dollar tps that does the same thing as the galant one, I'm still going to see what the difference circuitry wise the form of them might be different, that's the page I read on club3g before I went to work, about moving the wires it does not say why using the evo tps is different only the wire layout

So u have been using the evo TB with the stock IAC and TPS successfully without any problems it codes?? If that's the case I will keep the bare evo TB and won't sell it anymore.

You always bark about tuning, they're important yes but not for the reasons you always cite. The factory MAF and injector curves work if you use... guess what? Stock equipment. The injectors never need adjustment if they're working correctly and are clean, the MAF shouldn't either. That said the only "tuning" adjustments anyone needs to make on anything short of FI are to timing, fueling and accel enrichment tables.

Besides, the Fed Spec tunes whether for a galant or 3g 4 cylinder or 6 are about the farthest you can go with a street tune. Again talking about an NA build with stock injectors or MAF, if you do an engine swap and use say 6g74 injectors you need to compensate for them but you still use a factory curve. If you want to do better then you've gotta go to the dyno.

If anyone ever wants the V6 Fed Spec timing and fueling maps feel free to PM me, don't waste your money buying a "basemap" from someone, a tactrix cable and a hook up is all you need for the extra 10whp or so. Same goes for engine swaps, I have 74 and 75 basemaps for anyone who wants them also.

REALLY bark about tuning? you mah funny.

Anyways. When you change the intake, intake mani or TB. Check your Fuel trims. Let me know what you see GURU, then tell me if the computer needs to be adjust it to work with the new chances. The MAF sensor could do so much with the PCM or ECu to stay level when you change the fuel to air systems.

[duh2150]

Yeah, but I'm still curious is to why, I'm going to make sure the galant tps goes from 0 to 100% since there's still some confusion,

Ill pull that TB from the for sale thread for now then.

[JDyal]

Ok forgive me for being totally freakin lost...You can use the evo tb on the stock intake but it deletes your cruise, correct? I'm getting the evo tb is fine but you just can't use the evo im because it doesn't bolt up to the SOHC unless you do a DOHC swap...right?

[Isaurio]

FYI. The diamante TB is bigger than the evo. If the diamante fits why you going with a smaller one. LOL

[spdracr]

FYI. The diamante TB is bigger than the evo. If the diamante fits why you going with a smaller one. LOL

Then why aren't the evo guys using the diamante TB?? Lol Idk it just seems that most people that do the dohc swap they use the evo intake manifold and TB with it.

Oh my fucking god isaurio go crawl into a hole and play with your ECU coding, you have no idea what you're talking about here.

I will repeat myself for the sake of this fool.

ALL Mitsubishi throttle bodies share a bolt pattern, you could take any of them and bolt them onto whatever intake manifold you have. HOWEVER, there are a number of things you have to address when doing so because it makes a large difference.

BORE: On the 64, 72 and Evo throttle bodies the bore is CENTERED in the housing. This allows you to clock the throttle body without messing up the air track. The 74 bore is OFFSET so you can't clock it without messing up the air track. The other thing to take into consideration is the diameter of the bore. The intake manifold matches your stock throttle body, so if you're putting a bigger throttle body on it you either have to make the bore in the manifold match that of the new throttle body by porting it or use an intake manifold that matches the throttle body (like using the 74 manifold with the throttle body).

CABLE LOCATION: The EVO throttle cam is on the opposite side of the throttle body, this means that to run one you'll have to clock the throttle body and run the cable over the top of the manifold. The 64, 72, and 74 throttle bodies all have the cam on the same side so they are completely exchangeable as far as the cable location is concerned.

IAC: The 64, 72, and Evo throttle bodies use the same IAC's, you can use any of these throttle bodies without rewiring the TPS. The 6g74 throttle body however uses a larger IAC so you need that pigtail. The PIN OUTs are ALL identical though, so when you rewire the IAC for the 74 throttle body it is a 1 for 1 transplant between the pigtails.

TPS: The 64, 72 use identical TPS's, they are exchangeable in terms of plugging into your harness as well as the geometric design of the sensors.The 74 uses a different TPS in that it doesn't geometrically fit the other throttle bodies but the pinout and connector is the same so it also is plug and play. The EVO throttle body is completely different, it doesn't fit other throttle bodies and the pin out on the connector is different from that of the other throttle bodies so to use an Evo throttle body you have to repin the stock connector.

CRUISE CONTROL: The Evo throttle bodies don't have it. The 74 cruise is on the opposite side of the throttle body compared to stock and requires a small amount of influence against the sheet metal under the windshield wiper motor. The 72 cruise is identical to the 64's.

COOLANT FITTINGS: All these throttle bodies have a coolant chamber in the IAC housing. This get engine heat into the throttle body which works on a small coil (behind the small round plate on the bottom held in by one screw) that shuts a butterfly as the engine heats up. This is supposed to turn your idle down, but after bypassing the coolant on upwards of 10 throttle bodies and seeing no effects on idle I am telling you don't be afraid to pull the fittings out and just connect the two coolant hoses together to effectively bypass it.


Read the above a few times until you understand, the long story short is that you want the air tracks to match while maintaining functionability of the cable, TPS and IAC. Guys who do DOHC swap typically use the Evo throttle body because it matches that intake manifold without doing any port work, if you start matching things up from different motors you're going to have to customize things to make the most of them. Ultimately the 74 throttle body is the primo with a 75mm mouth, 65mm butterfly and 70mm housing port to the intake manifold. Using it however requires rewiring the IAC and some port work in most applications and that's why people look at other throttle bodies.

The easiest swap for the 4 popper guys hands down is the 6g72 throttle body. It is the exact same throttle body except the butterfly is bigger. It's 100% plug and play and takes only a moment to install. You also don't need to go any bigger really on a 4 cylinder boost build unless you're getting over 45 lbs/min of air into the engine.

V6 guys do the 74 throttle body in any case. It comes on the 74 and is the only sensible option for the 75 and still makes a big difference on the 72. If you want to get creative do a big bore Evo throttle body with the according work as required above.


And for Isaurio's comment... putting a larger throttle body on does nothing to change the size or dead times of your injectors. It doesn't change how much air per hz goes through the MAF either, all it does is allow more air to flow into the engine. Mitsubishi's air metering happens at the MAF and more air flowing into the engine will be metered. Don't play with me either, I have run 11 pounds on the same tune I ran 5 pounds with my turbo setup and the tune didn't change at all. The only thing that needs changing is the crappy cali spec fuel and ignition tables. A little more timing and less fuel leads will give you more power.

first question yes no more cruise control when using evo TB, second question it doesnt have to do with the SOHC or DOHC its about the TB flange, if your using the black 4g64 intake manifold the Tb flange is like 54mm wide, you can bolt a evo 60mm TB onto it yes, you can also bolt the v6 one on also from what behind said,

now you take the old 4g64 Tb off you have a 54mm TB hole flange, bolting a 60mm TB isnt going to make your inlet any bigger then 54mm,

now if you went DOHC youd have to buy a intake manifold and that would have a 60mm flange on it

Then why aren't the evo guys using the diamante TB?? Lol Idk it just seems that most people that do the dohc swap they use the evo intake manifold and TB with it.

from my guess 80% of evo owners don't know how to change their oil, the other 20% only think evo's, they can care less about kia head swaps, or 5 speed eclipse transmissions, ect.

when you go DOHC swap you have to buy another manifold so its makes since to buy a evo TB and Mani

the v6 works yes, but are you going to risk cutting the flange so skinny, its already a risk doing the 60mm evo one since the intake manifold cracks at the flange with the normal 4g64 TB on it, give me a little bit on time ill take my other 4g64 and take pics of the flange

[duh2150]

Heres my evo Tb with TPS i looked at both mine and the one on the engine both TPS look identical

How about u go back to the hole of club3g. That shit dont work here buddy. Dont come here thinking u are the shit and know it all you are nothing. U been picking information left and right and making it yours. That dont make you shit. Last time i check you runnig a big map rom that some like me wrote for your stupid ass. But know you think u know it all. Your are special right? Dude grow up.

Go ahed and talk all you want. When you have something original from your brain. The. We talk.

[spdracr]

Let me say one thing.

This dick measuring contest is the reason I went off the grid and became inactive and stopped coming online. U two have beef together then take it in private or just keep it to yourself. I posted this thread to get good info. Not to hear two grown up men fight like kids.

I will ask the mods to clean up this thread and keep it strictly for info.
