I have a 91 ef and I was wondering will a 90-91 ls trans line up with a b16 clutch?
I tried putting a gsr trans in but it wouldn't fit the clutch.

 

yes and no. yes if you use a b16 clutch that from cable b16 trans. no b16 from hydro trans will not fit.

 

No, that is "not" how it is!

Cable trans-

90-91- small spline mainshaft
92-93- large style mainshaft

Hydro Trans-

94-01- ALL large style mainshaft


So basically all 92+ b series clutches are interchange

and "all" years 1990-2001 have the same pressure plate, just a different clutch disk for the small 1990 and 91 models

 

WOW GOOD INFO!!!!!!!!!!!

 

so you saying a cable b16 clutch will not fit the 90-91 trans. because you are wrong. b16 cable will fit. all hydro and 92 up will not fit 90-91, but a cable b16 will. 90-91. i lnow cause i got a gsr cable trans.

 

I thought i was clear on this!

Hydro started in "1994" NOT 1992

There are "two" B16A clutches:

- 90-91 (small spline)
- 92+ (large spline)

So, if you have a 1990 or 91 Tranny, you need any 1990-91 B series clutch to fit your cable transmission

Oh, and btw, the "GSR" didn't some out till 1992. Yes it is cable as i have stated twice already, it will use any b series clutch from 1992 onwards. I have have cable YS1 in my own crx, it is large spline

 

Thank you

 

Ok, I have a B16a swap w/ a YS1 tranny and I need to put a new throw out bearing shift fork in it and a clutch but idk what kind of clutch or axles to but for it. The car is a 90' crx please help!
