its been 10 years but i did this swap in a 91 318is M42 motor im guessing it will be the same. If i remember right used a flywheel and clutch from a e30 325, I even took the flywheel and had most of the extra material removed at a machine shop did not have it balanced and never noticed it vibrating or doing anything else strange. It all bolted right up the only challenge i had was the starter. You need a starter from the same as the flywheel problem is it will not bolt up and work so you have to remove the gear from the 325 and but it in you 318 starter i don't remember the exact problem why i could not get it apart but i ended taking it to a shop that rebuilt starters and they exchanged them for me for not much money not sure what it cost but i do know i did not have much to spend at the time. |
