I finally got around to posting, and figured I'd start a build log..

The objective for my car was to build a great handling, fun to drive street car... details are as follows:

Car Specs: 2005 WRX WRX STI

Engine: Cosworth 2.5L longblock w/Cosworth Cams and Billet Crankshaft, 9.2:1 compression
Intake Manifold: Cosworth long runner
Exhaust: 3.5" turboback with APS 3.5" muffler

So far, I've dyno'd 520WHP at 22.5 psi on pump gas... running out of fuel.. since then, I've upgraded my fuel system and am planning to complete my tune in search of 550WHP on pump gas and 700+ on race gas.

Thus far, my best 1/4 mile time at 24 PSI on pump gas is an 11.4 at 125.5.. almost in the 10's. This was on a 90+ degree day, full weight and on 19's. I hope to break into the tens on pump gas once the weather cools off, with about 25psi.. hoping for 9's in the 140's on race gas.. we'll see..

Pics are as follows:








more updates to come...

It's a pretty awesome build Sigfried! I'm very happy that you took it to get the engine rebuilt too. lol, how long did you run on that old engine?!? I have no doubt you'll break into the 10's with that setup.

Very impressive specs!

Love how you kept the exterior stock!

Hey Julian,

My stock motor was on it's last leg for over 2 years before I decided to finally build it; cracked ring lands and low compression. My main concern was having an unreliable built motor; Phil and Element and Cosworth did a great job and I couldn't be happier.

brentcombsphoto,

Thasnks...... I went back and forth with body kits, but in the end decided to leave the stock parts on the car, albeit with some JDM bits (rear splitter, wing and lip). If I ever decide to mod the exterior, I'll probably install a widebody APR or Chargespeed kit; my biggest issue is having to baby the car due to the fragile aftermaket parts; I'd hate to deal with a yearly repaint due to cracked fiberglass parts.

For now, I'm just enjoying driving the car.

very sweet!

VERY nice
