Ok I have a 88 hf crx with a d16a6 in her and I just order a dohc zc full swap with zc trans but there's no half shaft.so I found a 88 si trans now I no it will bolt up fine but what I'm worryed about is will the clutch and flywheel that is already on the zc work with the si trans?

 

zc = si from below the head (basically) for parts. I rocked a Comp Clutch lt flywheel/clutch setup from 92-00 civic dseriez on my dohc zc 5 spd when it was in my 88 w/ d16a6 engine... (sold 88,kept tranz for the dohc zc eng found in jy last month,lol)

 

ok so basically ur saying that the clutch that's comeing in the zc is fine and will fit bc the blocks are pretty close to the came thing or a 92 00 clutch disk will work?

 

Almost ver batim to what I said,yes... (search the FAQ,or on net for dohc zc part interchange and you'd find all ur dohc zc answers...)

BTW,I uzed my dohc zc 5 spd w/ 88-89 integra halfshaft (intermediate),and DA (90-93) Integra axles after removing dust shields from spindles,and fabbing block adapter plate for the d16a6 block...

 

far as I understand 88 tranny = 88 clutch, splines are different

 

I hope ppl who read this don't think the integra halfshaft is a direct bolt up to the civic D series block. I'd like to see a pic of that adapter plate you had to fab to make it work.

Op,
Because you are trying to use a 88 Si tranny, because its an 88, you need a hybrid clutch kit to make it work with your flywheel or use a 88 flywheel. I suggest just buying the hybrid clutch kit from clutchcityonline.com. Great customer service, oe exedy stuff.

 

Never said it was "direct bolt in" (thus why teh ADAPTER plate mentioned-+ sure I'll post a pic sometime,when I'm even more bored than now,lol)

OP,figured that you already knew about teh 88's having smaller clutch/21 splines since you already owned an 88 hf-BUT ACT (and others) make a 21 splined (88's have 21,all other yrs = 20) clutch disc that also enables you to use teh larger later 90+ up years 212mm flywheel contact surface... ACT old part # 4P212K (4 puck,solid but they have others)
