Hi to all,I am from Singapore.I intend to buy a used Z3 manual 1.9L. I have a few questions:1. Is it easy to buy a half-cut M3?2. Is it easy to transplant an M3 engine into the Z3?3. If yes to #2, which workshop would you recommend?4. How long will it take?5. How much will the total cost be including the M3 half cut?Thanks.
