integra transmission

Does anyone know if all b-series clutches are interchangeable??? I have read here and there that 92-93 clutches, or some parts of them are in a seperate class and are different from the 90-91 and are also different from the 94-01 integras 99-00 si's and the b series del sols. I have a 93 integra and I am looking on ebay for a clutch kit.

I think all of the flywheels are the same!

But I'm not really sure and I would appreciate any feedback from someone that knows what they are talking about...

No, i previously thought that all b-series clutches were the same as well. But they are not, all 94-01 integra clutches are the same except for the b17, the b18ls+gsr have a 1 1/32-24 spline, that is shared with the si b16, both have that and a 8 5/8 plate size. All 90-93 b18's have a 31/32-24 spline with the same 8 5/8 plate. The only problem is that most of the discs that you get off of b18's will work on most all of them. I work at Summit Racing ( i know they dont have that much stuff but nonetheless) i ran into this problem with a guy with a 94 gsr. If you buy and entire set the books call for a different number, but if you piece one together they are all the same. The discs are the same for all 92-01 integras, and the pressure plate is the same for all 90-01 integras. Which leads me to believe that the throwout bearings have a different design. And for the b16, the same the disc is that same as all 92-01 integras, and the plate is the same on all 90-01 integras. It took me about an hour to piece together a kit for this guy, when i thought it would be so easy. :banghead:

the clutch disc is different because the shaft is different on the 92-01 trannys then the 90-91 thats why the clutch disc only works for 92-01 because they are all teh same even though it switches to hydro in 94 and the 92-93 is still cable.

its the throwout bearing thats different why because the 92-93 uses the cable setup while 94-01 use hydro. but i wouldnt count out the pilot bearing, do you konw anything about that ?

so heres kinda the run down

clutch disc
90-91 same
92-01 same

pressure plate like he said
90-01 same

throwout bearing
90-91, possbily 92-93 the same as 90-91 too, idk someone should look into that because they are all cable.
94-01 same

anyone know anything about pilot bearings, if they are all the same or what ?
