I have a friend that is currently researching the possibilities of building his motor, tranny, and a turbo kit for is 04 2.0l WRX. He is not necessarily limited by money but would rather stay on the lesser side of the spending. Where should he begin to look? What modifications will it require? How much would they cost? Especially pertaining to the transmission which will likely be his first modification since the current one is giving out. Give me details and links if you guys find the time. He has already decided upon the companies that will perform the labor and the tune.
Thanks,
