Impreza GC8 Pictures of my new engine and turbo buildup. Now JDM Version 8/5 hybrid, with a VF22.

The old shortblock: EJ205, JDM WRX Version 5 ('98 - '99) Type RA.

Bought with approx 50K miles, drove for around 18000 miles, suspected blown head gasket. Cylinder walls were pitted, decided to get a new engine.

The new shortblock: EJ207, JDM STI Version 8 ('04 - '05). 30K miles. Post professional cleaning:






I am using ARP head studs and a JDM complete gasket set. Crawford and others have convinced me to stick with the stock 3 layer stainless steel head gaskets. If Crawford can make 500WHP+ out of those, I don't think blowing them is going to be much of an issue with my 300 - 350WHP goals.

"The star that shines twice as bright, only lasts half as long"...


I want this one to last untill I can buy a 2005 STI. I.E. At least another year/ year and a half. I'm not too demanding, am I?
Of course, I also want it to run 11s in the 1/4 mile, so maybe I am being too ambitious.

Looking good. Just curious as to why you got a 5 angle valve job? Isn't 3 enough?

I'm not sure, but if I had to guess, I think it would have something to do with 2 blown motors, 2 blown transmissions, 2 ruined wheel bearings, 3 clutches, 2 flywheels, blown power steering pump and some other misc. stuff I'm probably forgetting.
I *love* the GC8, and it will lay waste to any stock STI, as well as look a lot better than anything Subaru has made since then... But the sad truth is that the drivetrain wasn't meant to make all this power and I am spending way too much money modding and fixing the car. I need a stronger base to build up from and a newer car that won't need as much regular maintenance. Plus the interior is better :P

That's just what the machine shop offered. Multi angle valve jobs flow more air at lower lifts, resulting in better throttle response.

why not go big 16g or 18g? especially if you want to run 11's... that way you wont have to push that 22 so hard that you blow the motor (again)

Its called "limited resources" That VF-22 cost me under $450, ported and polished and ceramic coated. How much is a big 16G or an 18G again?
Furthermore, if I wanted to run anything bigger than a VF-22 I would need larger injectors. Bigger injectors would require stand alone EM, and the power made would require a JDM transmission (even more than the VF22 already does). The JDM transmission is a different gear ratio, so it needs a new rear diff, the rear diff needs new half shafts, and I would also need a new clutch and flywheel. Oh, and a new slave cylinder too.
So VF22 it is

Exactly, you only went through so much trouble because you sold yourself short.. It woulda been more expensive upfront for a complete new age swap, but would been cheaper in the long run..

Good luck on the build..
