Noob M20B23 flywheel questions

[Wishno87]

I know I have seen these answers somewhere but I have been searching on and off the last few days and i cant for the life of me find the answers again. I just bought a M20B23 ltw flywheel a few days ago and im not sure which TO bearing I need to get for my M50 and G260. I have seen guys talking about using the 323 TO bearing for their M20B25 flywheels and G260s but what about if im using a 323 flywheel? Also I have a single mass eta clutch disc and PP that are almost new that I would like to use. Would that be a problem? Thanks in advance gentlemen.

Guys?

Anyone using a euro 323 flywheel on their m/sX swaps?

I am using that flywheel in my m20b25. It uses a regular TO bearing, same one that comes stock on 325i. If you check real OEM, the PN's are the same.
If you are using a single mass FW, you need a single mass clutch,PP, and TO bearing.
ETA's I believe all came with dual mass, so I dunno how you got a single mass ETA setup.
Also, I think if you are using the 323 FW, you also will need to use the starter from a 325i on your m/sx..unless they are the same.
Basically the starter, FW, clutch, PP and TO bearing all need to be from the same car.
Cant mix and match dual mass stuff with single mass, the thicknesses are wrong.

^ what he said. Just use the standard m20b25 TO bearing. You only have to use the 323 bearing when putting that FW on an m42.

Thanks for the responses guys. I think someone had converted my eta to a single mass flywheel. It still has the reference pins too. So then i should be able to use my single mass clutch kit off the eta then right? I think i have a b25 TO bearing somewhere too.

I have a 323 euro flywheel with a 323 euro throwout bearing on my s50

Your using a 260 right? What clutch did you use?

Yes, so long as all the components are from the same setup (single mass FW with single mass clutch disc and PP /TO bearing).

I may still have the single mass T/O bearing I pulled from my car when I replaced everything if you need it. But they are cheap, which is the reason I replaced mine while I was in there.

No, I'm using a g240 with m20 clutch and starter

I should not have any problem using a standard e30 325i small starter with the euro 323 flywheel right?

ETA's I believe all came with dual mass, so I dunno how you got a single mass ETA setup.

Not true some were assembled with single mass some with dual. I have parted 3 e's and of them 2 had single mass. One was an early 84 the other was a late 86 and the other was an 86 as well but had a dual mass.

I starter with single mass, would be nice to have the matching starter for flywheel but the thing is ancient so an i will do.

So those big huge starters are only for dual mass flywheels?
