i got a 2003 WRX with an STi swap with a stock 5-speed tranny pushing 340bhp and ive NEVER had any problems with the tranny. yes, ive launced it, raced it, etc.. everyone has said my trannys gonna go bad and i still havent had even a slight problem.

Whichever car you choose to buy, WRX or STi, you will definitely be satisfied!
