Confused on ZC motors...
 

I'm a little confused about the zc engine. I see it some places as a SOHC and others as a DOHC. Is the engine code for both d16zc? What car's did they come out off? Are they any good? VTEC or non-VTEC? I think I MIGHT look into buying a motor and building it, but if there is a D-Series DOHC I think I might want to consider that. I thought that ALL D-Series were SOHC, too. :-\ Can you guys please help me out here? For the longest time I have been trying to figure it out, but just can't. Thanks fellas! ;) ;D

there is a sohc and a dohc ZC, in my rex i had a sohc but there is a dohc. I think the parts are harder to find for the dohc. They are both non vtec.

Re: Confused on ZC motors...
 

I believe there was a SOHC Vtec ZC. Someone from outside the U.S. could vouch for that.

Re: Confused on ZC motors...
 

yes there is a sohc zc vtec and the code is simply zc. the dohc ones dont have as much aftermarket support but they are still great motors. the sohc zc is just a d16a6 with a little better cam. i would do the dohc zc, theyre basically a d16a6 bottom end, and theres a couple companys that make regrind cams for them. and you can find springs and retainers and all that stuff if you search around. as far as the bottom end you would probably be good using a high compression d16a6 piston cause it would still be lower cmpression than it would make in the a6 because the zc pistons (only dohc) have like a 7.2 dome or some ----. hope i made sense.

Re: Confused on ZC motors...
 

my sohc ZC in my rex wasnt vtec. It looked exactly like a d16a6 but the block was stamped ZC and it was a little bit quicker then the a6 :P

Re: Confused on ZC motors...
 

Same deal here. but some SOHC ZC's came with Vtec.

Re: Confused on ZC motors...
 

Word up. Thanks fellas. I'm probably better off finding another y8. LOL. Thanks for the knowledge anyway guys! ;) ;D

Re: Confused on ZC motors...
 

well to add to this post, when i had my rex and was going to get a dohc zc, i didn't because the parts list is weird, i like to be able to call up and say i have a 90 crx si 1.6, i need this this and this.... instead of i need a 19xx honda xxxxx head gasket and a 19xx.... you get the point. there was a list i had from someplace i think it was the zc resource, it had compatible parts...

Re: Confused on ZC motors...
 

dohc zc comes in 89 tegs...

Re: Confused on ZC motors...
 

no it doesn't, that is a d16a1.... i dare you to make it fit into a crx... i've read before of all the differences, but since i have been crxless for over a couple years i forget everything, i do know the mounts won't work

Re: Confused on ZC motors...
 

same ----. im sure you could fit it into a crx. probably just by changing the mount bracket on the driver side. but i dunno. never seen one of those d16a1's out of the car :-\

Re: Confused on ZC motors...
 

i have two first gen crx's both have 89 dohc zc, with electronic advance, no custom mounts or anything. if rpr was up i would post pics.

chris

Re: Confused on ZC motors...
 

i mean an 88-91 crx, a d16a1 will not fit into an 88-91 crx, and yeah i know the d16a1 fits into a first gen crx

Re: Confused on ZC motors...
 

and zc's only come in japan, dohc zc from 89 quint integras in japan. here in the US of A idge they only came as d16a1.... and no they will not bolt up to a second gen crx, the dohc zc that fit second gen crx's are the second generation zc, the way you can tell is the first gen zc have the bolts on the inside of the valve cover, and the second gen zc dohc's have the valve cover bolts on the outside. also the driver side mount is different and sticks out of the timing belt cover, where as the first gens the mount is on the front of the engine.

as soon as rpr is up i will post the pics. but the 89s had higher compression and electronic advance obd0

Re: Confused on ZC motors...
 

Finding the parts for the DOHC ZC is not hard at all. YOu just have to find the list on www.thezcr.com.

I the jist of things, Almost everything from the a6 will fit. The is a few different parts though. Gaskets usually come from the d16a1(88-89 integra(THIS WAS NOT A ZC! and will not fit 2nd Gen CRXS/4g Civics)) and timing belt from a DOHC 88 Prelude.

I have NEVER been able to not find a part for my DOHC.

Re: Confused on ZC motors...
 

Well, heck. LOL. I just paid attention to your signature and that's about what I was plannig on doing. Soooooooooo how is it ripping for ya?

Re: Confused on ZC motors...
 

dude, there's a CRX shell here for sale, $225, its flat black.. buy that ;)

Re: Confused on ZC motors...
 

so this isn't a dohc zc?
http://spoon.org/integra/enginepic2.jpg

didn't kno they made dual cam d16a1's

Re: Confused on ZC motors...
 

zc's are great engines.

SOHC non-vtec
DOHC non-vtec
SOHC vtec

those are the three kinds

The dual cam d series that came in the 1st gen tegs are D16A1 and are not a direct bolt on for 2nd/4th gen+ they are not ZC's. The ZCs that replace them are typically referred to as the brown tops, cause well most of them had brown valve covers.

So there it is. ZC's are cheap, if you want a cheap replacement you migjht wanna look into the jdm D15B vtec, those are also cheap.

Re: Confused on ZC motors...
 

d16a1 only came in dohc non vtec 1600 form 86-89 rs/ls integra. d16a6 is the 88-91 civic/crx si motor. dohc zc's motors there are 3 generations ranging from 85-94 and some even came with a downdraft carb on the brown/olive valve cover 1st gen.

Re: Confused on ZC motors...
 

i have an 89 black top single carbed, the distributer is vacume advance but it has the same bolt pattern as the electronic advance. so my motor is the basterd child of two generations. i'll post pics when rpr is up....

but yeah, that car rips, will never pass emissions but rips none the less.

Re: Confused on ZC motors...
 

I own a DOHC ZC and its a nice engine. The parts are a little funky (basically a D16A6 bottom end with a D16A1 head) but it has never been a problem you just need to look at a list to see what car part years/makes are compatable. There is aftermarket support... just not as much as B-Series but its definetly enough to build a fully built ZC you just need to look. Check out thezcr.com for more info on both the SOHC and DOHC ZC's. My DOHC ZC might be for sale (NJ area) as my car was totalled 4 weeks ago but im trying to just keep it.

Re: Confused on ZC motors...
 

In Japan DOHC ZC's came stock in civic and crx Si's from 84 all the way to the special edition EG hatch.

that's the 89 carbed used to be black top untill i stripped the valve cover.

http://www.redpepperracing.com/galle.../aaj.sized.jpg
that's the black top with a modified brown top vac advance dizzy, and that's turbo by the way.

Re: Confused on ZC motors...
 

Hmm.. a turbo DOHC ZC powered 1g CRX sounds good :D

Re: Confused on ZC motors...
 

when it's up and running with the 89 electronics and turbo edit, and 3 inch exhaust, i'll make a kick ass video.. with a 4th gear pull and some smoke..... muahahahahahah

at 5 psi the thing is insain, i wonder 10 hmmmm

no worries i have an intercooler already.... and some serous mendrell bent piping....

Re: Confused on ZC motors...
 

well we are on the subject lets discuss the ZCG, A friend told me that it is the rarest honda engine and it is pretty much a B16 (1.6 DOHC Vtec) that bolts to a d series tranny. I told him there was no such thing but he said he saw one, anyone else ever hear of suck a thing? This friend is a fairly reliable source too, he know his ---- but I just couldn't believe this one...? ??? Everything I have looked up says a ZCG is just a b16 and nothing about bolting up to a d series tranny...

Re: Confused on ZC motors...
 

dont forget the obd2 sohc zc motors 96+
96+ zc
96+ zc

Re: Confused on ZC motors...
 

does this reliable source smoke crack? There never was such a thing. Where did he see this b16a that bolts up too d series trans? Have him post I would love to hear this wonderful information

Re: Confused on ZC motors...
 

I had 2 brown tops ZC's..
Over here(europe) they are samped ZC1.
They look exaclty like the D16A1, but they are rated at 125 hp ro something like that.
I'm running a D16Z5(black top DOHC D16) with a ZC1 head, I bent the valves on the original head :(

Re: Confused on ZC motors...
 

I am trying to get a look at this motor for my self, I have heard of the infamous ZCG but not the d series tranny part, ZCG=B16A1 from what i know...I'll keep you updated, and I'm not sure about the smoking crack park
