[EuroDude]

"Zippy Civic"? :P

I'm not sure why they called it ZC, but from my understanding ZC's were the top of the range D-Series Civic/CRX engines before the B-Series came along with VTec.

The ZC is the DOHC version of the D16xx range, from what ive gathered.
Or in other words, any D-Series engine with DOHC is a ZC.

(correct me if i'm wrong ppl)



Some good info on ZC's:

ZC Identification Guide
The ZC engine is one of the hardest to identify because there are many different versions of this engine. Honda offered this engine in both single and dual overhead cam designs, as well as fuel injected and carbureted versions of these. This article distinguishes the different versions of the ZCs offered. Hopefully this will separate the facts from the myths.

The first ZC
ZC’s were first offered in Civic’s and Integra’s in 1985 and were still being manufactured in vehicles up until 2001. The first Generation ZC’s were offered from 1985 through 1987. These engines can be found in 85-87 JDM Civic’s and JDM CRX Si’s and were very similar to the 1986-1987 US Integra engine. It’s worth noting that this engine came with the highest horsepower rating of all ZCs at 137 horsepower. Remember, these engines were offered in Japan and similar versions offered in the United States were only offering 112 horsepower. The main difference is Japan’s higher quality gasoline and different fuel curves along with slightly higher compression. These engines are usually bolted into 1st generation Crx’s and 3rd Generation Civic’s along with 1986-1987 Integra’s. Most of this is pretty straight forward. The main problem lies within the carbureted versus fuel injected models offered during these years. This conversion is both difficult and time consuming and really not recommended because the results really aren’t that impressive.

The 2nd Generation of ZC's
In 1988 Honda introduced the second generation of ZC’s. These came with a black valve cover and have several differences when compared to the first generation ZC’s there. First, it’s important to realize that there are two types of ZC’s. The first, offered exclusively in JDM Civic’s/CRX’s, has ZC stamped on the block. The second is the D16A8/D16A9 and it came in USDM Acura Integra’s. These two engines are not interchangeable with one another and have different engine mounts. The Integra’s driver’s side mount is located near the front of the engine while the JDM ZC’s engine mount is closer to the timing belt cover. It is also worth noting that the valve covers and intake manifolds are also slightly different.

The 3rd Generation ZCs

Is there such a thing?
After 1992 in some Civics and a few 1994 and up Integra’s, still came with the odd model: the DOHC ZC. These ZCs look like the Civic style ZCs from 88-91 but have the later style electronics. There are even more Integra and Domani models with SOHC ZC engines. There is not a lot of interest in these (SOHC or DOHC) engines I am afraid, because the B-series VTEC motors bolt right in the 92 up Civics. The ZC does make a good swap in the lowly, underpowered CX or VX, but only with the EX, Si or ZC transmission, otherwise I don't recommend them. But for the sake of argument and to impress you with our large volume of trivial Honda knowledge, let's go ahead discuss them.

To recognize the 3rd generation DOHC ZC engine, just look for the black valve cover and 92 up grey colored electrical connectors. Some of the other visual clues are:

* a plug in the end of the exhaust cam, like the B-series motors
* two studs sticking up from the driver's side engine bracket poking out of the timing belt cover
* and no writing on the top of the intake manifold, just the three raised bars on the casting like all the other 92-95 Civic engines.

a zc is the same motor as a D16a8 expt its the jdm seres
it was used in crx integra and civic including the 4WD civic from japan
yes ive owned and rebuilt them many times (3 lol)
they use exactly the same parts inside out as the D16a8
its a twin cam 1590cc non v-tec with great results on turbos
and while its stats are close to what the D16z single cam v-tec is rated as
beleve me that they are much faster and have lots more torqe

dam that msg poped up while i was TYPING WOW

[bennjamin]

yes. This engine came locally in the 91-93 Si civic. And earlier CRX too.
