I need to know what clutch to use with a zc tranny on a zc block. Thanks.

 

It will all depend on what year ZC you have. You will use the clutch set for the civic/crx of the same year.

 

if you have the DOHC ZC i almost guarentee that its 86-89 integra, i know its not a single cam clutch for the civic or crx becuz i tried putting one in when i did the swap and it didnt work becuz the splines and the amount of teeth arnt the same.

 

I can guarantee it is going to depend on the year of the engine tranny combo.

Here is how it breaks down.

88 - 21 spline 190mm disk
89 - 20 spline 200mm disk
90 - 20 spline 210mm disk
91 - 20 spline 210mm disk

 

how do I know what year zc he has

 

its stamped on the exhaust manifold, two numbers like 90 or 88.

 

is that all? because the exhaust manifold that was with it is gone.

 

I have a '91 Civic Si, and on my ZC the two-digit number is cast into the head on the exhaust side, not on the exhaust manifold itself;
it is also a '91. I ordered a '91 Civic Si 3-piece factory clutch, as well as the pilot bearing, and they were all identical to what came out of
the '91 ZC.

part numbers for 1991 Civic Si:

pilot bearing 91006-634-008
friction disc 22200-PM7-L01
pressure plate 22300-PM7-L00
release bearing 22810-PL3-005

It is interesting to note the PM7 designation in the friction disc & pressure plate

good luck

 

thanks for all the help guys. I got it now
