m42 into a 318i

[Hick]

I believe early cars had a different, rectangular (as opposed to round) C101, so he'd have to make a wiring adapter. It shouldn't be too hard to figure out.

They still have some sort of plug for the engine harness. I think you are correct

ull be a fool to boost the m42 instend of the m10. keep the m10. Very strong motors.

Contact Jenny Morgan (CCA Tech Advisor)....She did a complete M42 swap on an early '82 or '83 build-date 318i 15 years ago. She knows more about M42's than anyone on this board. : )

all somewhat related.... not try8ing to get off subject but I saw the part about trannys and m42's

so I have two 91's with m42's. they are two months apart on build dates. the early one is a coupe, the later a vert. tow different tranny builders
one says getrig, and I could have sworn, the last time I was undr the cais it I could have sworn it said hect...maybe I was looking at the wrong thing
late at night when I looked, just got it a few days ago
Ill have to climb under them today and look again
but is this right
also the final drive says 4.1 but not have the "S" in fornt of it
so I guess my is does nto have limited slip, but I was told when I bought it , that it did
