I have read in countless articles that you can put an e36 m3 engine into an e30 325i. however, my main concern is that there is not enough room for air conditioner in there. I live in Texas and it gets insanely hot out here during the summer. So it's basically a necessity. Is there anyway that I can fit that m3 engine in there and still have air conditioning? Also, I have heard you can put a chevy small block engine (LS1 engine) in there but it's kind of a myth I think because I can't find any mounting kits. But anywho. Thanks for reading
