i have that setup on my 02 wrx and i works great. i would get better gears and them cryoed. i am running with a vf34 and i love it there like no turbo lag. i have never dyno the setup so i dont know what kind of number i would put down but i have heard from someone that has your same setup he put down 315whp. he ran a 12.6 at the track.
