hello BMW community, im a new 1994 BMW 325i owner and i bought the car with a bad motor and i was thinking of just buying a better motor than the 325i motor for it such as the 1999 and up M3 motor for it...yet before i was going to purchase the motor i was wondering if i could even do the swap successfully. would the motor fit? would it function properly? what details would i have to work out? how much would it all cost? id appreciate any and all advice you can lend to me. its great to be part of the community and thanks again.
If you go to (look up) E46 to E36 conversion under the M3 title you should come accross a string by myself (RITRKA & M3MKY) This may be of use. Since these posts, I'm not sure where M3MKY is up to with his conversion? His web site (found in the string) has not been updated in a little while. In short it can be done and physically it presents no problems. The problems arise (in my case) in getting the computors talking to your existing systems. I have an 98 328 and my problems is linking the computor to my traction control dash etc. I have spent months getting as much info as possible and as it stands I have yet to start as I dont want my car sitting up on blocks for 6 months while its worked out. There was a compant that emailed me stating that they were looking into the feasibility of producing a kit however my son reformatted my PC and I lost all my contacts (6 months worth). From my numerous conversations with BMW mechanics and email contacts it looks as though using a combination of both the E36 and E46 computors would have to be used. My limited knowledge tells me that the E46 and E36 use a different language of computors, a bit like E36 is Microsoft windows based and E46 is Mac based. This is a very rough analogy and I'm sure there are people in the community that can shed more light on it for you. Regardless, yes it can be done (as Ssias Tuning have done, see link) however to get it working as if factory will take some effort. This may be less applicable to a 94 as I'm not sure what existing systems you wish to run.
Good luck if you go ahead
