I have an e30 '84 318i and I was going to put in the M42 engine until I saw all the threads on here about the M44 engine. I'm now going to go with the M44 and would like to double check everything I am going to need to do the swap. Based on the other threads, let me see if I got this right.
I'll need: any M44 engine (96-99, they're all the same, 318i or Z3)
M42 wiring harness
M42 ECU
Is that the way to go? I was reading about how the M44 computer has the EWS immobilizer stuff in it so I should stay with the M42 computer and get it reprogrammed for the 1.9L displacement. Is it as simple as taking it to a dealership and they know what to do?
Also, what other little things will I need, like are the engine mount brackets the same? Different pulleys for the front end?
If anyone can give me a comprehensive idea of what all I need to make this happen I would greatly appreciate it
