I have a first generation b16a (converted to obd1) on a hydro transmission. The pressure plate (or isb) is shot I believe and im getting ready to replace it. I have a rebuilt y80 that I will be installing with a new clutch. So I'm hoping someone can give me some direction as to what clutch I need. basically do I buy the clutch for the transmission I have, or the engine I have?

 

you buy according to your transmission because they match the splines on the mainshaft
