How many splines are there, i'm putting a DOHC ZC, with a 88 si tranny and need to know what flywheel.

 

21 splines

 

Sio what flywheel should i use, an 88?

 

If you use the '88 transmission, you must use an '88 clutch. You should use a '88 flywheel, I am 80% sure you can use an '89 flywheel as well, but definately not the '90-'91 flyhweels.

If you can, find a '90-'91 si transmission since the clutch disc is larger for more surface, thus more grip and less wear. You would use a '90-91 clutch and f/w combo for this.

 

I know for 100% you can use an 89 Flywheel. Cause I have an 88 Trans, 21(spline) with a 89 DX car.

 

So i should use a 88 flywheel, Thanks for help

 

On kingmotorsports it says to use a 90-91 flywheel with the 88 clutchs

 

no, wont work. 88 clutch and PP are small. the PP wont mount up to the Flywheel. the bolt holes are spread out to far for a 88 PP.

 

88 - 21 Spline - 190mm Clutch/Pressure Plate/Flywheel
89 - 20 Spline - 200mm Clutch/Pressure Plate/Flywheel
90 - 20 Spline - 212mm Clutch/Pressure Plate/Flywheel
91 - 20 Spline - 212mm Clutch/Pressure Plate/Flywheel

If you would like to keep the 21 spline transmission, you can use a 84-87 Prelude 2.0L disk to achieve the 212mm clutch face and with this you can use the 90/91 Pressure Plate and Flywheel.

Sorry to ***** up this thread, but I have an 89 tranny and motor from a CRX Si. Are the larger 90-91 fw/clutch/pp direct replacements? I need to buy all three, but I've been getting mixed info on what will fit.

 

Yes they'll work, hence forth why both years are 20 splines.
