Non turbo. I'm seeing 9 1/2 and 8 7/8. Which one is the right one? 1981 280zx. 5 speed.

If it's the 2+2 in your other thread, then that car should have the 240mm flywheel.

2 seaters had the 225mm flywheel.

Make sure you match whatever flywheel you use. The PP and bearing collar are different between the two.

Yup, it is. And will do. That's funny, because I think the 260z that I'm swapping into also has the 240mm flywheel. Darn....oh well. I'll order the 8 and 7/8 inch clutch then. Thanks!

If that's the case wouldn't you want the 9 1/2" clutch since 240mm=roughly 9 1/2"?

Yes, I had 9 and a half in my mind when I typed the 8 inch in. ! Yeah, I will be getting the 9 1/2. Good call!

I remember that because I did the Turbo/2+2 clutch mod to my 280Z and my 810.

Haha, nice! Yeah, just ordered it and have it coming in tomorrow.
