I see that they make about the same amount of power, and the zc has a cr of 9.6:1? Which I guess could come up to about 10:1 for a little more power. Other than that, how does the sohc vtec fare against the dohc non-vtec? And how hard would either of these swaps be?

Alright, I look look around later when I have more time. I guess probably a lot of the questions I have have already probably been discussed to death on here

 

Only a few things I want to confirm:

The ZC is a little more torquey?

The ZC is obd-0 since it came in the same years as the EFs right?

Would I still need to to the DPFI --> MPFI conversion?

 

The ZC has more torque.

The ZC is OBD0 but it did come in a 92 hatch and it was OBD1 but the majority of ZC's are OBD0

If you have a std or dx model civic/crx you will need to convert from dpfi to mpfi

 

 

will the d15b vtec bolt up to the cable trans on an 89 crx si?

and will the stock d15b mounts bolt up to the 89 crx engine mounting points?

what ecu do you have to run to make it work?
