What year 735? Those got B35s in later years. It's totally worth it to have that B35 w/wiring harness. Early B35s are better for boosting.

745? I'd still grab the motor. Bolt up a better mani and roll with it. M102/106 FTW.

I aquired a 14lbs flywheel from a 1984 318i M10. I plan on using a HD clutch and PP as I am going to be running boost.

any new info on M50 flywheel on a M30 motor/trans/clutch setup? I know the 533/M5 is the preferred one but I have a M50 flywheel and a E34 M30B35 clutch kit. So will it work or am I going to waste my time attempting something that has been proven not to work?

The flywheel will bolt up - it won't work though. The short story is that the M20 / M50 flywheels are a slightly larger diameter than the M10 / M30 flywheels.

I attempted to defeat the internets running an M20 flywheel on mine, and it didn't work - there are two problems, First - the different diameter, although the difference seems to be in the ring gear, so you could try swapping the ring gear from an M10 or M30 flywheel to the M50 (although by that point you're probably better off just getting the correct flywheel).

The other problem is the starter bendix has a spacer in it on the M20 / M50, so the starter does not engage properly with the flywheel - eventually the ring gear fails. My ring gear lasted for a month.

If you want to run a 228mm clutch, then the Racehead Engineering flywheel is a good option if you can't find an old 2002 M10 flywheel.

Racehead also make a 240mm flywheel that would work with the clutch you've got:
