what if any are the differences between a USDM D16Z6 and the JDM ZC SOHC VTEC? im looking for a temporary replacement motor and am trying to stay away from a junk yard. but im having trouble finding a usdm motor.

 

The jdm zc sohc (d15b) has like 3-5 more hp than the usdm d16z6. It comes from the bump in the c/r. Thats the only diff i believe. Not too mention everyone thats always asking what water pump do i get for my d15b and all the other q's along with d15b's like that.

 

well all the zc's ive been seeing on websites are listed as a 1.6 liter. id rather just have the d16z6 myself.

 

Im happy with my z6, and if your wanting just a temp replacement, it would be cheaper.

 

yea, i just want to fix it and drive it. i blew it up and bought a newer hatch but now im in school and if it wasnt for my car payment on the car i absolutely hate (lol) i could pay for school out of my pocket. so basically im trying to avoid as much problems as possible by finding something to just drop in. but no one sells a USDM z6. and i would rather not have a junk yard motor. what a predicament.

 

yea the Jdm soch vtec ZC motor is actually a 1.6 and not the same as the d15b, it is identical to the z6 usdm motor.

 

Correct me if im wrong,but isn't the JDM Sohc ZC a Dohc D series from what I remember.

And no a D15B is not a ZC

 

Yea there is a dohc ZC also. They were talking about the sohc vtec ZC

 

would it directly replace the z6 then? is the ecu diff. can i run my p28. out of curiosity are the injectors bigger? and what problems do i run with a jdm motor? sensor diff or anything? (its my first import motor swap lol)

 

Im sure you could run your P28. Not sure on the sensors since its a JDM motor. I have a JDM type R and it has less things than the USDM version does.

 

well i guess i could just swap my intake mani right?

 

bump
I would like to know if I could just swap in a zc with my old tranny to . I have the d16z6 in a 94 civic also . Would like to just replace the motor and use the old ecu and tranny . Is it possible ?

 

Yes it is, every d-series tranny is swappable with no modifications

 

The zc vtec is basically a z6. The p28 and trans will work without issues.

 

yeah, pretty much, the only difference I can think of is the ZC doesn't have a purge solenoid on the back of the intake manifold, you can either swap your old D16Z6 manifold on (its 100% identical otherwise) or add the purge solenoid to the back of the intake manifold.

 

ZC SOHC VTEC engines have P28 stamped all over the parts- intake mani, pistons, etc.

I'm not sure about cam profile, but everything else is identical to D16Z6.

Why even post when you can't even comprehend what the original question is?
