So i want to use the 89 flywheel i have that has been lightened but i need to know if i can use the 90-91 clutch and pressure plate with this flywheel to get the 210mm clutch disc?
Anyone know for sure i have read a whole lot of misinformation about clutch sizes etc...

90-91 clutch will not fit 89 flywheel - 89 uses 200mm clutch and 90-91 uses 212mm - mounting holes for the pressure plate are not the same

 

i believe a 90-91 is a 21 spline and an 89 is a 20 spline as well so the disc won't slip on your input shaft if its a different year

 

Thanks counted the splines 20.
Guess i'll use the 89 stuff cause i already have the flywheel.

 

what are these pines you talk of i need to know because i'm going to do a clutch and i don't know what year the clutch is from.

 

the splines are the teeth on the end of the tranny input shaft, the ones that go through the clutch disk when you put the tranny on the car. I know 88 civics used a different size flywheel, clutch, and splines were different. (20) as opposed to 21. also pressure plate was different. these parts are not interchangeable. I myself do not know if 89 is the same as 88, more than likely they are. I put a 88 tranny on my 91 civic and found out flywheel, clutch,pressure plate are all different, wouldn't fit.

 

mmm pines
