So I picked a 1999 318 with a blown m43 motor. After looking into swaps the e46 seems to be a pita due to canbus. Now I am no stranger to making things work. I did the first ls swap into a nissan 240, had a 2jz mazda fd, and in my garage now I have my monster r33 gts25t and r32 gtr.
anyhow im here because I need need a motor and getting a m43 is out of the question. However it appears that the m44 is a great option that I can run on the m43 dme and harness but hw to do
6cyl swaps are popular to, a good motor to turbo is a m52b28, just with freshing up the motor, getting a mls head gasket and arp head studs you can have 400 hp reliably for a very long time, some users have no trouble with 500 to 550.
Id need a rhd donor car for all this and thats not happening. At this point I just want to picknup a good used m44, freshen it up, dress it m43 and get this car running
