IIRC t's the same as the non-turbo 20.

However, you can use the KA flywheel with the KA clutch on most (all?) push-type RBs.

I had an R34 RB25 Neo with a KA24 clutch/flywheel, worked great.

what about a KA flywheel with a 300zx na clutch????

From what I've read I think that works... I've never had them lined up with eachother though.

The big difference between the RB25, RB20 flywheel and the KA, is
the contact patche. With the KA your limited to a 225mm clutch,
compared to 250mm for the RB.

If I'm not mistaken the 300zx clutche is a 250mm, so this would mean
that it would rub against the outside lip of the flywheel, I think.
I can't remember what would it, but something on the ka flywheel was
in the way, so the 250mm disc would rub it.

At least that's what I remember, could be a little bit wrong, after all
last time I looked for that info was like 2-3 years ago.

Someone should correct me if I'm wrong. But I'm fairly certain.
