Does all M20 share same clutch?

[Mr. Horsepower]

Looking for clutch for my automatic-manual convention om Ebay.

I wonder if all the M20 clutches fit all M20 flywheel?
I'm checking out the F1 Stage 3 clutch kit for 86-91 BMW 325 325i 325is E30 M20. Mine M20 is a B20.

that kit will indeed work with your flywheel.

but to answer your question, m20 clutches are not identical, but they are interchangeable.

[Mr. Horsepower]

Interchangeable was the word I was looking for! Thanks :)

As long as you have a single-mass flywheel

[Mr. Horsepower]

Does the S14 flywheel fit as an upgrade?

[MR 325]

Not positive on that but another idea is you can run an S14 clutch on M20 flywheel.

[Mr. Horsepower]

Maybe they share the same flywheel?

I will compare them when I get my M20 flywheel. I have a S14 flywheel after fitting aluminum flywheel. S14 flywheel weights 7.3kg.
