Curious, I am going to swap a sohc zc into my 90 Civic Std. Now, the axles and shift linkage, where would I get those from? Also, is the zc transmission or the si tranny better? What ecu works, does the one from the dohc zc work? Thanks in advance

get a zc ecu

 

if you are using the ZC transmission u will need the ZC intermediate shaft with integra axles. the zc intermediate shaft is hard to find....my friend swapped a SOHC ZC into her CRX. shes lookng for a SI tranny now since she can't find a intermediate shaft for the ZC tranny.

 

The SOHC ZC tranny is not similar to the DOHC ZC tranny. It does not have a half shaft, infact IIRC it's exactly like the Si tranny, use it. If you use an Si tranny you can use all your stock parts (shift linkage, axles).

Basically a SOHC ZC swap is like dropping an Si motor in your car, all you need is MPFI swap and a PM6 ECU.

I miss my SOHC ZC.

 

SOHC ZC does have a intermediate shaft....i'm almost postive. i've been looking for one for my friend for over a month.

ZC tranny has even shorter gear ratios then the SI...

with final drive, gear ratios are: (the higher the number, the shorter the gears)

ZC
1st - 12.63
2nd - 7.56
3rd - 5.22
4th - 4.01
5th - 3.41

Si
1st - 13.81
2nd - 8.05
3rd - 5.35
4th - 3.98
5th - 3.28

 

i didn't say which was better. i just stated that it was shorter.
