yes and no.

a M20's flywheel and clutch will bolt in, but you will also have to change the drive gear in the starter to match the new flywheel.

you can also get a european single mass M42 flywheel/clutch and keep the original starter.

i have a single mass E30M3 flywheel/clutch and have been wanting to see if i can get it to work. i know that the crank bolts and spacing are the same, as well as the splines of the trans input shaft and the starter ring gear. i just have to work out the correct stack height.
