i swapped a jdm t2 motor in my 91, s5, n/a but at the time i didnt bother with the drivetrain, i put the n/a flywheel on the t2 motor and used my stock clutch and flywheel, tranny, driveshaft and rear end. now that im ready to swap my drivetrain i've got an s5 (cosmo) tranny, s5 driveshaft, s4 rear end and the axles.. all i have left is the clutch and flywheel to find. i know the flywheel is series specific due to the counterweights but what about the clutch? i've found a couple good deals on s4 clutches is there anyway to make them work with my setup? thanks in advance!

 

S5 cosmo transmission? You Kouki? Anywho, stock flywheel is ENGINE series specific, since it has a built in counterweight. Must come from same series engine only. Clutch will work regardless, just make sure its a TII s4, or s5.

The S5 clutches are 235mm (stock) and the s4 are 240mm (stock). They can be interchanged no problem though.
