Some of you may remember the WRX I did with a GT30R. Well, I redid the engine with a built 2.5 liter block (sleeves, rods, pistons) and ported the heads. Installed a custom Godspeed large MAF intake, back to the dyno and picked up some great power. Here's the dyno sheet. Made 382 WHP on 93 octane at 20 PSI and 472 WHP on 100 octane fuel at 25 PSI. Turbo is pretty much maxed out at this point and since it was only 100 octane unleaded and not C16 I did not want to push it. Still excellent results and the car is just plain crazy fast on the street. Customer wants more still so a Spec R 650 kit is in his future. Stock camshafts are holding back quite a bit of power unfortunately but he had no budget left for that so we left them stock. With cams I'm sure we could hit 400 WHP on pump fuel. We'll see if we can hit that with the SPec R 650 turbo and stock cams. Should be no problem.
