m20 flywheels and clutches

Question

I thought this would be simple, but the internet can't seem to come to a consensus about this one.

Looking for a single-mass m20 flywheel and clutch. ECS Tuning and Pelican Parts both can't seem to decide what part number is what, or which one comes from which application.

Don't really care if it's OEM or aftermarket, but I'm looking for light-ish flywheel and clutch to hold ~250 ft-lbs that will give stock-ish feel without rattle.

Please help.

Assuming you want this for your m42? I did a lightened stock m20 single mass for my nice car and had to use an e21 323 throwout bearing I believe. It should all be in my build thread. Otherwise valeo and a few people make single mass setups that you could get lightened

That thread is 70 pages long 😒

I would just look up the part number for the flywheel on realoem, but I'd have to know what year/model to look at, and there is a lot of conflicting information about which cars were single-mass...

Also, finish your car.

Thanks.

For flywheels, RHD engineering makes what looks like a really nice steel flywheel for a good price. I believe @MattY has an M20 specific one he is going to put in his car so he could give some feedback on quality. They make one for the M42 that allows you to keep the stock starter and uses an M20 clutch disk/pressure plate.

I saw those, and the price seems astonishingly low considering the work that must go into making them. It's still an option, but I was actually worried it would be too light and cause trans rattle at idle. Not the worst problem to have, but I'd still like to avoid it if possible.
