Swapping M44 (1998) into an e30 (M40)

[oomesh]

I would really appreciate if someone could help. I recently ordered a second hand m42 from a 1995 e36. But unfortunately, only an m44 from 1998 ti is available (complete engine with wiring and ecu). do you think this swap is possible for my e30 with current m40 engine? i've read that sensors are different, and i should cater for ignition bearings,...?
WHATS THE DIFFERENCE BET M42 and M44?
Kindly advice me.
