What clutch to use with Euro 323i Flywheel???

[bubbajan21]

I am in the process of an M50 swap and I have decided on the Euro E21 323i flywheel. My car is an 1987 325es, and I will be using the Getrag 260 out of it. I have researched, and i know I will need to use M20 flywheel bolts, it will clear the E34 oil pan, and I will use the M20 starter, but I can't find a definitive answer on what clutch to use. I will be using a Sachs clutch, but I'm not sure which one. I know that since I am going from a daul-mass flywheel with a solid hub clutch to a single-mass flywheel, I will need a sprung hub clutch, so basically a clutch from another single mass car. Bavauto sells 3 kits:
1986-1992 325i
1984-1986 325e
1987-1992 E30 M3

I think the 84-86 325e clutch is what I need, but I have seen people say that they used late model 325i clutches and M3 clutches. If somebody knows which clutch I need, or even better, if somebody has used one of these clutches with a 323 flywheel and a Getrag 260, I would very much appreciate the assistance.

I just used a single mass 325i setup for my 323.

The other difficulty I've been having is finding concise and clear info as to what years and what models were single mass or daul mass. I'm fairly certain the 84-86 etas were all single mass, but I've also seen people who were absolutely certain the 86-92 325i's were all single mass, as well as people who were certain they were all daul mass. Any idea which of these you used?

im running zf 5 speed with m20 flywheel+ clutch+ m20 starter, zf t/B an P/B. all etas are single mass, also 325i's are single mass. 318i are dual

Im using the m20 with the euro 323 flywheel on my s50

[bubbajan21]

all etas are single mass, also 325i's are single mass. 318i are dual

This is the kind of misinformation I am having such a hard time picking through. I know for a fact that not all etas are single mass, I have an eta that is daul mass. Does anybody know simply which of the three clutches above is for use in a single mass M20?

[bubbajan21]

I'm not sure how accurate their system is, but according to autopartswarehouse.com, all three of these clutches are sprung hub. I'm definitely not going with an M3 clutch due to price, but is it possible that either the 84-86 e clutch or the 86-92 I clutch would work? Although, in thinking about it, if they were interchangeable then why would their be two different kits?

I think I order the m20 clutch for a late model 325i but I don't remember exactly

[glucklich21]

I have a 323i flywheel. There's two versions, a pre 9/84 and post. Pre is (PN 11221264517) and weighs 13.6# and post (same PN as ETA's). So the one you want for your swap is 11221264517. You will need a 323i throw out bearing (it is NOT the same as a 89 325i, I do not care what they say, the two are physically different) and you can use a standard late model 325i clutch and pressure plate.

I'm running a Spec Stage 2 323i setup on my S50.

The matching flywheel bolts are PN 11227805885.

BTW bmwmercedesparts.com has them for $225 new, I don't know what Blunt is asking, but it's worth asking.

Thank you so much, your post was very helpful!
I've been talking with blunt about the 517 flywheel, so that is all good. Do you know if 21 51 1 204 525 is the right 323i TO bearing? That's $75, which is rather annoying since I will end up with 2 when I buy the kit. So the 86-92 325i clutch is the one to use? Do you know if the pilot bearing in that kit is the right one to use? I believe it is since I am using all M20 stuff in the stock E30 transmission.

[glucklich21]

The 525 throw out bearing is the correct one. You can always resell the extra one. The pilot bearing should be the same (12mm). The G240 uses a 15mm if I recall correctly, so don't order that one by mistake. As for that clutch, it should be good.

[bubbajan21]

Alright, so with your guys' help, I think I've got it all figured out.

323i Flywheel....11221264517
323i Throw-Out Bearing....21511204525
( 8 ) Flywheel Bolts....11227805885
Bavauto 1986-1992 325i Clutch Kit

And with these parts I should be good to go to bolt everything all up and drop it into my E30.

Thanks Guys!:up:

P.S. Anybody want to buy an M20 Throw-out Bearing?;)

Trying to help put the correct info out there:

9/83-4/86 etas: SINGLE MASS Bellhousing depth- 6 1/2
5/86-6/88 etas: DUAL/TWIN MASS Bellhousing depth- 6 7/8
325i: SINGLE MASS Bellhousing depth- 6 1/2
318is m42: dual
And i believe the m10 318's have single.

If you have a trans from a twin mass car going on a single mass, use the 323i throw out.
