Yes, it will fit. Here are the mods that need to be done.

- M3 transmission
- M3 engine
- M3 DME
- M3 cluster
- M3 LCM
- M3 shifter parts
- M3 engine harness
- M3 body harness, adapted for non-M sedan (rear windows (???), sport button, etc.)
- Traction control??
- Speed sensors?
- all necessary brackets, etc. etc.

All of which, you have to find and do yourself. Your best bet would be to find a wrecked (in the rear) M3, strip both cars down, and swap all the M3 parts into the 325... we're talking every single part here. This will end up costing you a fortune of money and time, especially on the research end of things.
