I just picked up an 88 Si tranny and wanted to know if I could use an 89 Si Flywheel with the 88 clutch assembly, or will only the 88 flywheel work? They are both 200mm so I thought it may work or does the spline count matter?

 

You can use the 89 flywheel. The clutch disc is dependent on the spline count of the transmission.

 

that is what i wanted to hear. thanks a lot man
