6g75

[MGB2003]

People are going their own ways with engine builds such as WarmAndSCSI and boostzealot with the 6G72 and the 6G74. I was wondering if the 6G75 could be a possible swap. Not the MIVEC version, but the 230 hp version.

[WarmAndSCSI]

You're not going to elicit much interest on TGC. The swap is completely unproven. Check this out, it'll answer a lot of your questions: http://www.club3g.com/forum/3g-eclipse-gt-gts-specific/71416-3-8-6g75-swap-discussion.html

Just as a side note, the 6G75 upper plenum with the 6G74 TB bolted up (6G75 TB is drive-by-wire) would be an awesome swap for 6G72 owners.

Also that engine is too new. I haven't done my research about it, but I doubt junkyards have a 6g75 engine or a busted V6 9G Galant. It would be cool to see what fits and how it can be installed, if it can be installed.

[WarmAndSCSI]

Lots of junkyards have these.

Well then I guess I'm the only that doesn't have one, I've yet to see a V6 9G Galant down, here. The most I see are the ones with the Lancer Ralliart engine

Just found 2 full pages of 9G 6G75's. There are plenty around. Although it's been very rare that I've found anything useful locally even though we have like 20 junkyards.

[MGB2003]

That sucks. I wish someone could try the complete swap (engine and transmission) in an 8G. I want to go with a V6 instead of staying with the 4G64 even though it can boast some good numbers as far as boost is concerned. The 6G72, 6G74, and 6G75 are just more powerful setups, especially when its tuned.

[WarmAndSCSI]

4G64 boosted is a far easier-to-work-on platform. More work that you realize would be involved in a V6 swap to begin with, yet alone a 6G75 swap.

How so?

[WarmAndSCSI]

How so?
To what?

[boostzealot]

X2. ever heard of AMS? yeah man i would love to advocate the v6 swap into a 64 based chasis but there are far more simple ways to make the power you want. not to mention the 64 has great potential and can provide the power delivery that you may be looking for (i.e. low end torque and a fat powerband). good luck in your journeys where ever you go and make certain to pay attention to the guys who know what we.. uh they, are talking about. lol sorry i couldnt cover that one up.

[RedGalant2k1]

To what?

6g75 plenum.

[boostzealot]

it was confirmed on club3g that the 75's upper mani fits on the 74 or the 72 by dragon34x.

[WarmAndSCSI]

6g75 plenum.
Can't find any photos right now. My reasoning: it appears to flow much better than the GTS or Diamante plenums (larger diameter runners) plus it eliminates that PITA 90 degree bend required to hook any intake or charge piping up to the TB.

[6G72gearhead]

It sure would be handy to eliminate that extreme bend.

[boostzealot]

my goodness it looks funny in these engine bays though

[WarmAndSCSI]

It sure would be handy to eliminate that extreme bend.
Yep, both to eliminate some turbulence and for convenience. The only place you want a bit of turbulence is in the lower intake and intake ports where the fuel is atomized.

[6G72gearhead]

Thus the use of multiple valves instead of large single valves.

[6G72gearhead]

In the cylinder head that is.

[wright06jhs]

not sure if this would be any helpful info, but my local junkyard has an 9g 4cyl in it..with pretty low miles. I think there under 20k

It would be of help if we were talking about 4G69's.

[6G72gearhead]

why would you bring a 4 banger into a V6 conversation.

[boostzealot]

someone is apparently not reading the thread.....

I know that the 4G64 is a great engine to build upon, but I just wanted to go with a V6. If I could find another Galant with a V6 in good condition, I would trade mine for it. But, more than likely I will just stick with the 4G64 and build it up. I just wanted to try something different.

[boostzealot]

please dont mistake us for downing you on this project, we arent saying you shouldnt, its just that i imagine you would save yourself some money turboing the 64 ya know.

[WarmAndSCSI]

This is so true. From people who dump a ton of money into 6G7x projects, please just stay with the 4G64!

[boostzealot]

yep i have spent about $6k in just two months on my car and thats still not with the itb,s , the emanage ultimate, the machine work, and getting the car functional again. ugghhh

[WarmAndSCSI]

Prepare for at least $900 including tax for your machine work. That's what the 6G72 cost me to just get machined. If I had been paying a regular speed shop to do the assembly, parts, and installation as well it would have been somewhere around $7k just for the first rebuild last fall.

6G7x modification is expensive, at least 2x more than 4G6x!

[MGB2003]

Thanks, I am just going to stick with the 4G64. What do you guys think would be better to do first? Doing work to the block or going turbo? I planning on going 5-speed before working on the engine. Also, what would be the best injectors to use?

[fatal1]

well if your going to turbo it its always better to do any supporting mods beforehand, if you build teh block etc you will be able to run much higher boost when you slap on the turbo
