What you have and its mileage is important in deciding between forced induction vs a swap. I see M3 engines often on ebay; here is one that is a little over priced: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33615&item=2441725399

Theres even a e46 m3 engine with SMG transmission for sale also. But I think if you have a pre 96 car --getting a 3.2L M3 engine, and doing a OBD1 changeover will yield a good bit of power.
