hi every1, i got a cdb out of my 96 sti ra. i had an accident in the car so i broke it but im left with the cdb which i intend to rebuild for a big power 2 door in the future.
im after around 500bhp, what would be a good spec engine for this power. im on a bit of a budget as the car may be a demo car for my buisness i plan to start up in the nea future. i will be building the engine myself, and have acsess to machining shops if needs be. will my v2 sti heads be up to the job and what sort of cams/valvetrain are needed. what about stroker kits?
let me know what u think.
cheers people.
