We have begun the search for a new project. I am trying to find a 1988-1991 325i/is at an auction to do either an M50/52 or S50/52 engine swap in. Right now we are looking at a $8,000 budget, and I would like to find the M50 that came out of a Z3 because of the lighter aluminum block (the only one BMW ever made). If anybody see's one for sale, please drop me a line.
