Going from m10 to m42

[gemini325es]

Hi I got a slamming deal on a m42 engine and wiring harness. I wanted to know of this swap has been done before. I have a 84 318i 5spd and wanting to swap in the m42. How difficult is this. I'm familier with wiring and such. Wanted to know if there was a write up some where of someone doing it documenting what was done. Thanks.

Its been done about a million times in 2002's. I would check out some of their forums

I've got the driveshaft with a good pre-87 CSB needed for this swap.

whut? his drive shaft should be ok, and if not he would still need the m42/g240 d/s from post 90...

Just to clarify, pre 87 CSB's have a different bolt pattern than post 87'. The driveshaft I have is a 91' 318is, with a good CSB, that was used on a 84' 318 with a m42 swap.

9 of 87, it turns out- my 2-87 has the early tunnel...

oh, and search 'c-101' for a lot of helpful stuff on splicing a body harness to an engine harness.
You DID get the engine harness and ECU, right?

(If I had it, I'd swap the body harness too. Probably take only a bit more time than
splicing, and 1/10 the aggro. Plus, you'll find $5 in loose change while you're in there.)
