Before I installed the turbo I wanted to make sure my highway revs wouldn't land me in the boost all the time. So I decided to swap the stock e36 m3 5-speed ZF box out for the e46 6-speed Getreg box. The Euro 6spd cross member and shift linkage were needed. The automatic e36 M3 driveshaft was used, and the clutch and flywheel are for an e46 since the splines on the e46 box are different than the e36.
