I have been checking for about a week about what axles and clutch I need for the DOHC ZC swap, using the ZC tranny and intermediate shaft, and I found a few different "facts" so I just want to make sure.

Clutch for ZC tranny--21 splines=1988 USDM CRX clutch
20 splines=measure it, just under 8"=1989 CRX clutch
around 8 3/4"=90-91 CRX clutch

Axles---with ZC intermediate shaft and tranny --90-93 integra axles

so can anyone verify this is the right information?

 

with ZC transmission you need ZC intermediate shaft and 90-93 Integra axles - the clutch you need will depend on what year the ZC transmission is (which you won't know until you get it) - if it is 88 it will have 21 splines on the input shaft and if it is 89-91, it will have 20 splines - if the engine/transmission is from 88-89 it will have a flywheel for a 200mm diameter clutch - if it is 90-91 it will have flywheel for 212mm diameter clutch - if it is 89, you can upgrade to the larger 212mm clutch by using 90-00 flywheel

 

thanks man, so the info I ended up with was correct, sweet!!
