    M10 to M42 swap!

    Yes i know most of you will probably say "what the hell why do all that work when you can do a m50 for almost the same price" haha well i have my reasons why but i need to know all the stuff that i will need to complete the swap. i might be picking up a m42 with tranny this week but what are the other needs?

    Thanks guys,
    Brad

    harness/dme, radiator, all appropriate sensors, getrag 240 (late model tranny, early one that is found in the 84 318i will not fit), shift linkage, driveshaft.

                I just picked up a m42, tranny, clutch, radiator, drive shaft, ecu, and few other odds and ends for 400! going to re seal everything, clean it up, and paint! then drop it in this summer. Ill probably start a build thread when we get going! Thanks for the help so far guys im sure ill be asking a lot of questions about this lol

                      according to realoem.com a 83 318i and an 91 318is are not using the same front
                      sub-frame, well at least the part numbers are not the same.

                          while the subframe is out, weld in some of those tabs from turner that reinforce the motor mounts. and throw a new steering rack in while everything is out as well. the perfect time.
