I've bought a m20 flywheel that i had resurfaced and a 325i clutch kit that comes with a T/O bearing. Can i use that T/O bearing or do i need the one from the 323?

In realoem.com, the part numbers are the same for an E30 318is and and a 323i. From that it appears that the 1991 E30 318is TOB should work with the M20 Flywheel and clutch.

no, I just checked realoem and it's the e21 323i TOB we need (or do we?)

The one you found is for the e30 323. it is also the same as the e30 325i and many others.

The clutch we use is out of the 325I not the 325e right?

its out of the 325i/is

edit:
yes, it is the E21 part that is needed

stuartgallafant · « **Reply #11 on:** March 24, 2007, 09:52:20 AM »

i have this mod to do on my iS too. why do you need the E21 323i T/O bearing? will the M20 one not work? i was under the impression that all M20 clutches and release bearings were the same

I have just put my engine and gearbox together using an lightened M20 Flywheel, 325 Clucth, 323 TO Bearing (which is actually used on 320's as well, but the dealer told me it was only on really early cars) and the engine has gone in to the car today, can't wait to get it running it's only done 37K Miles!:)

I have piccies comparing the IS, 325 and 323 T/O bearings if someone can host them I will post them up, they are quite different, you can see why you need the 323 bearing as it's quite a lot longer and the tabs are in different places.

Does anyone know if you can re-use the bolts from the m42 assembly to attach the M20 pressure plate to the M20 flywheel?
