Hey all I'm at odds with what to decide on doing and need some suggestions (some advice wouldn't be bad either.) Well here's my dilemma; I have a bmw M50B25 out of a 1992 325is complete with everything except the flywheel and clutch in my garage and I wanna know what you guys think of swapping it into a Z would be like or should i just stick to swapping init the L26 with the round top SU's I got with the car? If i were to swap in the M50b25 i would want to run boost on it because stock they can handle a conservative setup of 8-12psi, but the real dilemma is that I'm kinda unsure of the swap because It's never been done before and I don't really want to open up a pandora's box of problems. People have told me that the engine is relatively simple but that's not always the case. Anyways I'd gladly appreciate any input you guys have as to this swap. Oh and the engine itself is a stand alone system so wiring shouldn't be too much of a hassle.
