Hmmm. H6 with sti trans??? Any ideas?

[rudd]

I have been thinking about doing a h6 swap and doing a turbo kit and putting the sti trans behind that motor.. One problem If I'm correct the bell housing won't bolt up to the h6 motor... I know the shop in nc had a hell of a time doing this swap into a 2000 rs... Any ideas or thoughts.

Unless you either have a ton of money or a lot a free time and knowledge I wouldn't do it. Its a lot more work than throwing a kit on it or else a lot more people would be running them.

It would be epic, that is my thought. Good luck.

If you want to talk to someone who did it call PDX. They built one for Perrin awhile ago.

[tribalwrx]

Actually just look up the build it was well documented , you'll see what your facing with that under taking

[granny]

^^^ Yeah I have the thread somewhere. Ill look for it tomorrow.

[tribalwrx]

I believe you'll find it in the proven power bragging thread

Good luck. It's an extremely involved project.

Someone needs to adjust their shift light RPM

the bellhousing bolt pattern is the same

[Kiwi Fella]

In talking to installers there was not a lot of gain on effort

[coldfiremx]

You could get a used porsche for the price of that build if you did it right, an it will have a flat6 and 6 speeds to row through.

[Carter]

Yep, the only gain is the sound, and you'd might as well just get the Porsche.

I believe I read once, they use the Tribeca transmission on the Auto STI's in Japan/Australia?

All the EJ, EG, and EZ transmissions bolt up. The swaps have been done and if you really want to then do your research and ignore everyone here telling you not too. Just make sure you know what your up against. Lots of wiring to do, and depending on which 6 you go with determines how much fab work needs done along with engine management.

i planned on doing this and found it hard to source parts like cams and pistons that didnt cost an arm and a leg.

[rudd]

That's what I have been looking for is upgraded parts... But I still haven't found anything as of yet

Yeah what he said, don't listen to what anyone else said. It sounds like its worth it. Keep us posted on the updates.

The rods, pistons, ect were all custom made on the build I followed. Lots of $$$

[zachary.berrier]

Hahahaha, yep. Was completely custom for Jeff Perrin if i remember right

[snowdrift86]

The parts are out there. And are found pretty easy in australian market where the h6 is modded consistently it seems due to having manual trans option over there. In 5 minutes I've found super tech pistons, couple rod options and some can choices. Cosmetic head gaskets and forms of tuning people have been successful with. if your looking for simple quick and easy this is not that swap lol. But like I said if its what your goal is then get on it

[rudd]

I just think it would be sick in a wrx I seen one in a 00 rs and it was sick fast and it was na with a Cobb pro tune done. I wasn't sure about a few things lie wiring and motor supports and wat needs to be done to get the motor bolted up. I would prob. Pay some one to do the wiring one I hate wiring and I hate following wiring diagrams lol I know it can be done and if done its a real nice set up with lots of potential like autocross.... The rs I seen with this set up us quick on the track.... I was kinda wondering what everyone thought about it that's all a lot of good thoughts and I'm still trying to decide if I want that build or take my 2.0 out and build the hell out of it and have fun...

[snowdrift86]

If I was you I would choose the EZ30D or R if you are wanting the works (AVCS/AVLS). That and they require little work to actually into the engine bay where as the EG33 requires some core support and radiator placement work. It's longer due to timing belt and the addition of two cylinders. EZ's are chain drivin so they fit almost like a 2.5. Not much longer . I would love to EZ30R swap my wife's '10 OBS but her car is still under the warranty. And I have no time to or money to start acquiring the parts

k well, my last ej257 build was around $10k and 15 months and that was with alot of favors from folks like Seth at P3 (thanks amillion by the way those who helped) dont get me wrong im sure alot of us would be stoked to see a build like this but who has $20k and two years of time to do this that's not someone like Jeff Perrin.
