ok i am working out a trade with a kid on a 89 civic 4 door. he says he orderd an engine from a place in ohio that is a single overhead cam non vtec ZC engine. i saw the stamp on it and it did have zc on it and i didnt think to much about it. but then i got home and i thought about it some more and i have never heard of a single overhead cam non vtec engine before also i remember it had the dpfi intake manifold on it. is it possible to run the mpfi engine with the dpfi intake. someone set me straight because i am all confused about this one.

Yes,it is possible to run DPFI on a MPFI engine or vice-versa..

hey thanks for the info, that is a great site, now what about that engine has anyone ever heard of it or what does this guy have it confused with?also wouldnt it be better to have the si intake on it?

 

anyone have any info?

 

yes there are single cam zc's
there is a vtec version and a non vtec version
infact there are lots of non vtec single cams

 

huh, never knew that,i knew there where single cam non vtec but i didnt know there was a single cam non vtec zc. what years of what cars did the sohc zc non vtec engine come in?

 

civic, CRX 88-91 JDM

was it basicaly the 88-91 si engine over in japan? what is the horse power on it? i am guessing it is a 1.6L and what is the difference between it and the U.S. 88-91 si engine?

 

what i understand it was pretty much the DX engine and i believe correct me if im wrong, it was the engine in the 88-89 Si and the 90-91 DX. The 90-91 Si's had the DOHC ZC. The engine is pretty much the D16A6 with more HP. some people say it has the same HP as the counter DOHC model which is 130hp and others say it only has 119hp. I never owned one so i dont know.

 

actually the SOHC ZC engines that are being imported en masse it seems like, are from japanese integras, not CRX. anyway, all the SOHC ZC engine information is here. it came in carb and fuel injected versions. the bottom end is completely identical to an A6, but the cam is *slightly* different, depending on if its carbed or MPFI.

what is the engine code on the mpfi 88-89 sohc engine? i want to make sure that the kid is not feeding me a line. everything seems ligit, just never hurts to check it out.

 

itll just be "ZC".

 

really, i think that is what i saw. how old would that engine be though because he said that he got it from a place in ohio and they told him it only had 17000 on it?

 

how old? how many miles? shrug. just look at my link, theyve been making SOHC ZC's since 88.

 

ok i got some more info. i really dont think this kid is trying to rip me off i just dont know if the company he got the engine from ripped him off. he said he did not have to switch up any of the wiring on the civic 4 door dx so i am assuming it is still a dpfi system did they make the sohc zc able to run on the dpfi?

 

doesnt matter. even if the ZC was teh carbed version, you take off all the intake stuff and put the old DPFI or whatever on and itll run just like the old engine, except with the different cam, which no one else really knows or cares about.

you run the same system the old engine was basically. the sensors are all on the intake manifold.

well to find out how old it is, if it has the same head from the manufacture. look at the head stamp it will be around the middle front (ex side) its a round stamp with a line in it (8l9) would be a 90 year model or (9l6) would be a 97 year model the sohc zc comes with about 110-115hp (si ecu) on our pump gas (92 octane) not much more without bolt ons get it

but i thought the sohc zc no vtec was a mpfi fuel injection system that would require two more injectors and a resistor box, or doesnt it really matter as long as the intake is swapped?

 

nope just bolt on his Intake manifold, and put in his distributor, bolt that sucker in and he can be on the road....make sure to charge him extra for all the headaches.

whats this guy trying to do...go MPFI from DPFI?

Or does he have DPFI now and just wants a motor to stick in it.

Either way Bolt the motor in his car, If the motor you have is MPFI and he wants stock injection on his car then swap the Intake manifolds and distributor from his old motor.

I dont see what there is not to get man, Have you EVER done a motor swap in your life?

The SOHC he has (ZC) is almost identical to what he has now.

ok first off please do not put me down because i did not know something. i had never heard of the sohc zc non vtec, and i am posting in a section that is ment to help people when they dont know something. the swap is already done and i was making sure i was not getting ripped off. i hate it when people put you down because you are not the all knowing honda gods that they are. when people ask me a question i just try and help, i just dont put them down for not knowing something. grow up and treat the honda-tech fourm the way it should be treated. also i did not reolize that when i wrote the post it sounded like the swap was not done yet. so that is why i ask what because it did not make sence to me why i would have to bolt on another distributor and intake

 

my bad for coming across as an ***, It did come out a little wrong...but cool that its done I thought it was still to be done.

But nah you didnt get ripped off at all, its basically just a replacement motor anyway, you dont really gain a whole lot from a SOHC ZC anyway, theyre really not any stronger than the D16A6, just a few HP like 3-5 i think.

 

no harm done man,i dindnt reolize how i had written it. thanks alot for the info. i learned alot from it. yeah i think it will work out. i was just looking for a winter beater so performance is not all that important. it will end up costing me about 900 bucks so i think that is a pretty good deal. it has a solid body wich was the most important. thanks again man

 

i told you, whether its DPFI, MPFI, or carburated, that all has to do with the intake manifold and is completely separate to the engine. thats how ppl can do DPFI-&gt;MPFI, just bolt on the appropriate intake astuff and sensors on the same engine.

for some reason, these SOHC ZC are being shipped to america by the crate load and are ending up in ppls cars as direct replacements as cheap. engine distributors have them wall to wall in warehouses. im finding them in the junkyard even. just consider it a d16a6, with a very minor difference in cam profile.
