It's Blue, ok?


go for it!!!

IMHO, the vf30 will have too much turbo lag for autox. I would tweak the stock turbo instead to keep the low end boost response.

There are no limitation on the engine, so as long as the displacement, forced induction, and weight combo is in place you are fine!

Heh throw another .4 or .5L of displacement at it! What turbo lag! The FP turbo I've heard has a bit of lag as well. I've seen good things with the iON reworked turbo. I'm going with an APS SR30 turbo personally. But it almost makes me sad to say that a STi in stock form (with larger R-compounds) may be faster than my car is going to be this year. Slap a bigger turbo on it and it should do 400hp without a problem.
