Im going to sound real dumb here but am stumped.

Now when I bought my last car from the auction ( 92 Civic HB), it has a ZC motor swap with p28 ecu, but the vtec is not working and the Check engine light is on.

I have no idea why it wouldnt work, the car drives good, but no vtec. Sorry im a noob at this stuff.

Any help is greatly appreciated.

 

a ZC doesnt have vtec

are you sure about that???

my SOHC ZC has vtec. It's the JDM version of the D16Z6.

Clarify which ZC you have

 

Are you talking about the old school non-vtec DOHC 1.6 litre engine or a z6 sohc.

i was thinking the DOHC ZC's, i have never seen a DOHC zc with vtec, and yeah the SOHC could have vtec (u know about them more then i do)

 

This is where i get lost...Is there numbers i can post to know if it really is Vtec? I know it says ZC on block and then there are numbers underneath it.

The valve cover says VTEC on it, but for all i know the Valve cover was just put on cause they didnt have another.

 

Make sure the oil is up to the proper level, change it as well.

and also make sure coolant level is good, if there is air in the coolant vtec does not always engage.

 

Is it DOHC OR SOHC?

 

SOHC

 

then i would start with the basic stuff, check oil levels, coolant, vac lines. go from there.

 

check if it has a vtec solinoid.

 

check your codes first....may be that vtec isn't wired up, ecu is bad, etc etc.

Could be a lot of things....you gotta help yourself out before we can try and help

 

Ok here are some pics of the engine...

 

looks like a vx motor.. it's got egr and what looks like a 5wire o2.. the im looks the same but the TB is 10x's bigger..

 

what auction did you get it from btw?

 

looks like the engine harness has the vtec plugs....but y0, you need to get rid of that exhaust manifold, like yesterday bro! lol

you can unplug the ecu, and see if the harness is pinned properly for vtec....I can't think of the locations off tha dome right now though....

thinking the same thing..but if the block's stamped ZC....the car is probably a VX and he is just using the ZC longblock with the VX IM and EM

thas what i was thinkin.. haha.. i like that valve cover though..

 

Hey that valve cover is custom

I have no idea if they used VX head, but it is a CX model car.

I wish I could explain more but I did not have the engine installed.

 

look like a vx motor to me. notice the cat under that heat shield also where the o2 sensor is... must be a vx

 

smaller im, cat in header = vx id say

It took you a couple hours to change a dizzy? haha just kidding with you.

Post a picture of the block stamp.

 

yea but I thought a Economy motor is not a ZC block? I could be wrong and probably am. I will have pic of stamp in morning.

 

now if the Head is from a VX motor, cant I just put a vtec head on? since it is a ZC long block
