that increase in power should not be too drastic to have to change trannys, bmw is really reserved in trannys, basically im sure the tranny could handle 40hp extra...and if not, lets go get a stickier clutch from uuc or somewhere else, the 330 clutch is just bigger in diameter, same material used....BMW's are mechanically very well off.
