What about the e21 323i flywheel?

are you saying that if you use a single mass m42 flywheel you can use the stock m42 starter and clutch kit. what if you have a/c can you use the single mass fw?

The single mass flywheel works with the twin mass starter. The single mass flywheel uses a different clutch kit and flywheel bolts, however.

Lmfao that clutch was toast, hope you at least sanded the flywheel down, if not you might as well pull it apart to remove the glaze, and that pilot bearing is clearly dry.

ahhaha... the flywheel was machined... and most parts replaced for new

the flywheel weighs 24lbs and the clutch kit weighs 14lbs

Sorry for bringing back an old thread but i am trying to find a sprung clutch disk that will fit between an Alum M42 flywheel and M42 dual mass pressure plate.Can someone explain to me why the M42 single mass clutch disk wil not work with an M42 aluminum flywheel and M42 dual mass PP? Is there not enough room for it to spin? If they have the same spline and same dia. then as long as it fits and spins with reasonable clearance then it should work.No?
Thanks
Glen

Just for the record, a late model M20 starter will bolt right up... no need to change pinion gears.

Which year M20 starter is considered a late model? Would you happen to have a part number for the above? Thx!

Readily available M20 single-mass flywheels can easily, cheaply, and safely be taken down to 11 pounds. The starter and TOB options are easy!

Of course, there are always other flywheels that have been used with great results. It's up to you if you want to piece the assembly together.

So can you use a e30 325i TOB with the m20 flywheel with acceptable results?
