M20 flywheel conversion
« Reply #30 on: May 20, 2007, 10:48:44 AM »
Can you give us the part # of the TO bearing you are using?

On RealOEM it has a different part listing for 323 models up to 84' (21511204525) which looks different from the part you have and is incidentally is the part I have. Does anyone know if either of the TO bearings listed for the 323 will work?

(The other TO bearing for the 323 is 21517521471)

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.

The flywheel has a lip on the engine side that may foul the engine and most have it machined off, it also gives the added bonus of lightening the flywheel!

Did you (or can you) just have this done at a regular machine shop or is this something that you have to take to a performance shop that specializes in lightening & balancing flywheels?

You should be able to take it to a regular machine shop, but check they are good and make sure that the wheel is clocked up and runs true before you start machining. Whether you also have it balanced is up to you, i didn't because I trust the guy who did it and the wheel ran perefectly true before machining.

Runs great with no vibrations so must be ok!

At the same time I had som more removed from the back face to get rid of some more weight!
