asking if theres a sifu in here that knows

im planning to buy an e46 320i some time in the future, but i also have plans to swap the n42 engine with a n20.

question is, will the n20 fit? actually not fit or not, will it be "ngam" ? scared diff mounting positions and gearbox not ngam and all. but the main point is, is it possible to fit the n20 inside the e46 320i?
