4 Speed Tranny Same Clutch?

Hi,

I really need to get a clutch for my civic STD with the 4 speed tranny.
I am thinking of getting an exedy off of ebay or anything that is better and grips more then the stock clutch.
Does it matter between the 4 speed and 5 speed tranny what clutch u use? Arent they both interchagable?
Thanks

I dont want to mislead anybody.

No they aren't interchangable. They have different imput shafts. If I were you since you wanna do the MPFI swap I would get an Si tranny or at least a Dx.
