I am looking for a D16Z6 to put into my CRX but they are pretty hard to come by. I came across the ZC VTEC on a few sites and it looks pretty much identical to a Z6 is it the same thing but JDM??? It says ZC on the block too, as far as parts go what usdm parts would I have to buy to maintain this motor as a daily driver??

 

SOHC ZC is non vtec. DOHC ZC is non vtec. the only 2 SOHC VTEC motors are the usdm d16z6 and the jdm d15b. I see you live in funky town, im like 5 min away in agg town and i got a d16z6 block and head i could prolly sell you

 

Um i think you are mistaken homie. I'm pretty sure that it really was a 1.6,SOHC vtec that didnt say D16z6 on the block. Only because I saw the photo of the engine code on the block. It either is an SOHC VTEC ZC from japan or its a ZC motor with a Z6 head of something.

 

no there is such thing as a zc 1.6 sohc vtec, dont know much about it, but if u search it has been confirmed there is such a motor

 

JDM only had SOHC Non-vtec (ZC), DOHC non-vtec. (ZC).

The only SOHC VTEC I can think of that is the D15B. I know there is a 3-stage vtec, but that is mainly for fuel economy.

Your right i was mistaken homie, i left out the y8. thats vtec too.

my bad.

 

its basically an a6 bottom end and vtec head. they were offered in the 92-95 civics. if the price is right grab it.

 

didnt the sohc zc vtec motor come in european civics?

 

so its a good motor? but nobody from this forum could answer my question about what parts to buy for the said motor.

 

There is infact a sohc vtec zc..Its basically the same as the d16z6 except it supposedly has around 140hp and comes in the jdm cars..

I dont think europe cars have zc motors..None of the edm motors ive seen have had zc stamped on the blocks..Even the motor in the 88-91 civic over there that is identical to the zc motor is called something different,,,Like d16a8/9..Or something like that..

 

HumanResource posted this over on D-Series...best ZC break down I've seen to date. What I really like is that it's references that actual Honda.jp archives for verification, not my buddys sisters boyfriend had...

I think a lot of the confusion around the sohc vtec zc comes from the fact it wasn't offered in a Civic, but rather the Domani.

With all the misinformation spread across the internet, this post is to clarify the misconceptions about “ZC” engines.

In earlier “Hybrid” years (1996-1997) many people were buying DOHC 1590cc engines stamped “ZC” from engine importers. These engines were popular upgrades for Civic/CRX chassis providing ~130ps with bolt in ease. This engine was called “THE ZC” for quite a number of years, and even today people still consider this twin cam the ONLY ZC. Engine importers received a variety of other engines stamped “ZC”. The “ZC” stamp alone cannot identify the engine’s designation. The only thing one can assume is that ALL engines stamped “ZC” displaces 1590cc. “ZC” stamped engines were offered with a number of design variations throughout the years of production.
Here’s a TIMELINE of the different “ZC” engines manufactured that I have noted thus far:

Okay if I buy a SOHC ZC VTEC what USDM parts do i buy when ever it comes to do meintenance? Sorry the search option isnt working for me. Basically i need to know what water pump, timing belt, tensioner, etc. to buy after I get the motor. Thanks for your help.

 

Just buy a D16z6 Cmon u know u want to do it *gentle push*

-Jon

Well I have a civic and it comes with a 1.6 sohc vtec zc engine

 

shut your freakin mouth you charlatan keep off Honda tech and stick to Wikipedia

sohc zc blocks with p08-3 heads exits from the dealer

never in the US

 

difference is the block the zc block has .5 mm larger bore than the z6 block they both are obd1 z6 vtec offered to the states 92-95. Zc vtec maybe only offered for 1996 they both use the same head and accessories
