can a s15 clutch be used on a s13 sr?

i want to know what is the difference between a s15 sr clutch and a s13 sr clutch

can i use a s15 clutch on my s13 sr motor and tranny?

anyone?

I dont think so. From any type of application/product numbers Ive looked at, the S15 clutch is different. I think it may have something to do with the 6spd trans bellhousing? Truthfully not sure though.

This is a Zilvia type question.
