Quick question, I was trying to find the diameter of the stock CA clutch and the only thread i found was one that stated it was 9 inches. Now, its been awhile since i've had the clutch out of my car but 9 inches seems a little on the small side. Can anyone tell me what the diameter is?

Referring to the pressure plate. ACT is yellow (even though they don't really make a CA kit) and im pretty sure SPEC is blue, so the only other options that i know of for the CA are really expensive. So i was wondering what kind of crazy setup that is? As in who makes it?

Sounds like a nice setup. I hope you're putting some power through there to let that clutch stretch its legs.

Thanks a bunch for all the info guys....but seriously, i wanna see some tattered and torn, beaten to death clutches on your CA's. You guys are babying those things! :)

@ jezz_s13those specs from the manual are different again to our manual here is australia

i think the ca18de is a smaller clutch than a CA18det

anyways... thats the size clutch we have have in ours ..love to know why the difference tho

Mmm, that clip is from the Nissan FSM that someone in Australia scanned IIRC. It's the S13 200sx manual for the CA18DET.

How odd. :confused:
