What clutch do i need? I have a 90 crx with built a gsr and 93 gsr cable trans, pulled the gsr trans to swap in the s1 and the clutch doesnt fit? so im guessing the s1 takes something special? thanks alot

 

S1's and J1's have the smaller input shaft, and they require a 90-91 integra style clutch. YS1's have bigger input shafts. The clutches are not interchangeable. You'll have to get a 90-91 Integra clutch if you want to use that S1.
