ok i need to know, i have a tranny i bought and its a si but im not sure what the year is. the tranny has a spline count of 20 (so i know its a 89-91) i read that the flywheel for an '89 is 200mm, while the '90-'91 is 212mm.....so the question is... if i happen to have a '89 would the '90-'91 clutch/flywheel still fit the tranny? thanks for any info

thanks i guess (for a vauge reply/coment)

 

well i dont get it why wouldnt it fit i mean... if its an 89 tranny for the si im pretty sure that you can bolt up a 90 and up flywheel no problem... or did i hear wrong because i posted a thread not to long ago the title was "flywheel...." and everybody was saying that i could use the 90 and up flywheel.... but i think that it is different if you were gonna try to use the 89' clutch with the 90up flywheel..... now im really confused......

 

Some of the flywheels have a diff pin spacing, the pins that the pressure plate bolt onto. You have to have the right flywheel for the pressureplace/clutch disk and spline count for the mainshaft.

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.</TD></TR></TABLE>

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.</TD></TR></TABLE>

These are all good facts, the Docs info is usually correct

sorry its complicated. i had an 89 si and i had to change my clutch it took me awaile to figure it out. i had to use an eg fly wheel w/the 89 clutch.

sorry

 

Here's the easy way to figure out the transmission's year [It's *possible* that it's not 100% on every single D-series tranny, but it's worked 100% for me so far, on well over 50 L3s...]

Look at the end of the input shaft, where it goes into the flywheel and pilot bearing. You have the splines, which engage the clutch, but look further out toward the end of the shaft, and you should see a groove around the circumference of the input shaft. If there is NO groove at all (it's just a thin groove machined into the metal of the shaft, less than 1/16" wide), then it should be an '88 transmission (and it should have 21 splines on the input shaft as well); if there is ONE groove, it's an '89; it if has TWO grooves, it's a '90 or '91.

Voila. Done.

Like I said, with Honda, ANYTHING is possible, but this method has not failed me yet.

</TD></TR></TABLE>i dunno what stage they call it since their street disc is sprung and this one is unsprung. i paid 350 , plus an extra 125 when they sent me a bent disc and claimed that there was no way that was possible. clutchmaster products customer service
