granted i have a newer sti, but just to give you an idea to get 365 whp it cost me 4500. changed the turbo,inj.,fuel pump,up pipe,and cai. we did dyno at 392 but felt the psi was just too much. my point is nothings cheap and everyone that claims they want 400whp because 350 isnt enough in this little car is high as a kite. everytime i take off in this car and punch it i can understand why the thread "do you really want 400whp?" was made. and i came from 450 hp mustangs.
