im looking at an act clutch for my z6 swap in my 91 Si... i have a 91 Si trans. im just trying to make sure the 89-91 civic/crx clutches are the same

 

yep just get one for a 91 and your good to go

 

Ive got an ACT stage 1 with a XACT 8lb flywheel.. Best money i ever spent for a clutch. It holds with conviction, but is still tolerable for daily driving. I would highly recommend them to anyone who likes a more performance oriented experience from their ef.

and yes, a 91 si trans to a z6 just needs all 91 components, clutch, flywheel and pressure plate..

 

a nice street disk would serve the purpose like a dual friction..., but ACT does make a nice 6 puck as well.
