Okay, so iv been searching all day for information on some stuff about swapping the b25 into a 325e and haven't found good answers. So, things I know, or at least think I know, need an the I flywheel, but iv got a new clutch in the E, will it bolt up? And by new I mean maybe 10k on it? Next question is exhaust, from what Iv read there's really no difference in exhaust manifolds, I have a cat back exhaust that I fabricated, so the only section that would be from the E car is the headers down to the cat, can I run this on the b25? Or is there some casting difference? From what Iv read there isn't any difference but correct me if I'm wrong. Now would be wiring, I undestand there will be wiring to deal with, but what exactly is to be done? Just cut the c101 connector off the car side and rewire it to the E? And does a E water pump just bolt right up? That way I can keep the E cooling system? Thanks guy, if there's any links that I may have missed please send them to me. Sorry If this has been asked somewhere else. Iv not found any good answers on the wiring portion of the swap
