i have a jdm dohc zc in an 89 crx hf.... and im trying 2 figure out what kinda of clutch i need 2 get....

 

what tranny and fly wheel do u have?

 

i have the 1 that came with the swap.... it was an engine and trans combo

 

depends on the year of the engine/flywheel/transmission you have - 88, you need clutch for 88 CRX Si - 89, you need clutch for 89 CRX/Civic Si - 90 or 91, you need clutch for 90-91 CRX/Civic Si

 

see thats the thing... i was reading up on something that said that the zc clutch is slightly smaller than the Si clutch.... idk.. how do i find out what year it is?

 

bump

 

Try looking on top of your exhaust header #2 or #3 their should be a year number '88-89 / '90-91.

so if your engine is an 89 and your tranny is lets say a 91 dx tranny then all i need is a clutch for a 89 civic/crx ?

</TD></TR></TABLE>yes, if it has the 89 flywheel - let me clear this up a little - the clutch you need depends on which flywheel and which transmission you have, not necessarily the engine - a lot of DOHC ZC swaps are done with people buying just a longblock (could even be from an automatic) and using the flywheel that was on their original engine - this thread started out by Lilstreetracer88 saying he purchased the ZC engine and transmission combination, in which case it is probably reasonable to assume that his flywheel is the same year as his engine and that he would be pretty safe in buying a clutch for the year of his engine without having to remove the transmission to find out what year the transmission is or what size flywheel he has

 

so im good 2 go when i find out the year? just buy an si clutc with the same year?

 

ok well i jsut recently bought a dohc zc . its an 89 engine , i looked on the block and it says 89. it came with a dx tranny attatched but i dont know if it was even on the engine when it was running because the bolts holding it on where barely on at all. any ways.. so the tranny does have something to do with which clutch you buy? im going to be using the dx tranny in my car now for the zc its a 91 car.. so i just buy a clutch for a 91 dx?

yes

why don't you switch out the flywheel while you're at it if you've got the funds

 

once the zc trans has been pulled from the zc and a foreign trans (hf/dx/std/si) trans has been bolted up, there's really no way of telling until you pll the trans and count the number of splines on the transmission input shaft.

 

kinda wierd it goes by the transmition not the engine because the clutch bolts up the the engine.

unless you were the one putting the tranny on the engine and knew what kind it was.

 

the 1988 trans have a different spline count on the input shaft than the 89-00 d-series trans.

 

You dont have to count the splines on the tranny. On the end of the input shaft there is either 1 ring, 2 rings, or no rings. 0 rings = 88 tranny, 1 ring =89 tranny and 2 rings = 90-91 tranny.

If you have a 89 tranny you can use the 90-91 clutch if you get a 90-91 flywheel which will allow you to use the bigger clutch setup. If you have a 88 tranny you can still use the bigger clutch setup by using the 90-91 flywheel with a 88 accord or 87 prelude clutch disc and 90-91 PP. Some companies sell this combo as the 88 "upgrade".

HTH

 

okay, either way you still can't tell and both methods will work.

 

so if i have an 89 zc with an 89 flywheel and a 91 dx tranny i would have to put a 90-91 flywheel on the engine?

You wouldnt have to but it would give you more clutch area if you used the 90-91 clutch setup.

 

well i guess i'll put my 91 d15b2 fly wheel on the zc then.
