DOHC ZC?
I happened to come upon this motor I its claims to be a ZC but I've never seen this before. Anyone have any info on it? http://cgi.ebay.com/ebaymotors...33615

Re: (redzcstandardhatch)
This is why I hate Ebay in regards to Honda stuff....... if it doesn't say ZC on the block it's not a ZC........ DUH. In regards to info on ZC's, here's a clip from a ZC resource I got a while back......

The D16A6.
The 88-91 CRX Si and Civic Si. SOHC 1.6 non VTEC. All Si owners out there know this is a good solid engine. The 88 made 105 hp and the 89-91 made 108 hp and 100 ft/lbs. tourqe. You can pick up a running engine for about $400, usually with some kind of short-term warranty. This engine should be one to consider if you own a DX. For the same price as a basic bolt-on like a header or exhaust you can boost your output from 92 HP to 105-108. That's an increase of 13-16 HP. For a DX owner that has swapped in an Si engine, added an intake, header, and exhaust will see an output increase of 30-33 hp. Does this sound appealing to anyone? If you swap int he Si engine you'd be best to consider picking up the Si transmission, it’s geared for acceleration vs. the DX cruising and fuel economy.
The JDM ZC. The term ZC covers quite a few different engines. The types I’m aware of are:
DOHC 1.6 Non VTEC, Black valve cover.
When people say ZC, this is the engine most of them will be referring to. It is rated at roughly 130 hp and 108 ft/lbs. of torque. (This engine is very similar to the North American Acura Integra of 88-89(D16A1). The difference being the location of the mounts and head.) This engine is called the D16A8 and A9 in Europe. It was available in the Japanese market CRX from 88-91 and remained available in a lower end Integra until 93. This engine will bolt right in, no fabrication of mounts and no wiring problems. THe only problem is that the buldge on the timing belt cover will rub on our CRX hoods. That is why ZC'd CRX's and Civic's came with a hood that is baciaclly the same as our except for the buldge above where the valve cover is located. If you’re on a budget, you can even use your old si ecu, exhaust manifold and transmission, Just be warned that these will choke up the quoted 130 hp to less.
DOHC 1.6 Non VTEC, Brown valve cover.
Basically the same as the above engine except for the fact that it has 5 hp more. Why exactly I'm not sure. I will do research and update this.
1.6 Non VTEC, Olive valve cover.
A predecessor of the black valve cover, it’s power output is less @ 115 hp and the mounts are different. Given the lower hp and mounts that will require some fabrication, skip this one in favor of the black valve cover.
SOHC 1.6 Non VTEC.
This one is hard to get hold of but it’s out there. It looks nearly identical to the si D16A6 but is rumored to have a more aggressive cam and the same domed pistons that are in the black valve cover DOHC model that raises the compression ratio over the flat top pistons on the D16A6. It makes around 120 hp. Personally I would not go an search for this engine because of the fact that it is rare. When it brakes, where will you get parts?
The ZC is a great engine. Its DOHC design makes it rev high smoother than the SOHC Honda engines. If you add adjustable cam gears, the DOHC engines are easier to tune, with better results. Many people get them expecting a drastic difference but are disappointed with the results. This is because of a few reasons. First of all, expectation. People believe that the DOHC will push them back in their seats but what it really does is allow the car move a little quicker. Age, worn out engine, mismatched components etc. Get a healthy engine, the ZC ecu, the short-geared transmission, and an adequate header and it will run circles around the stock si engine BUT if you remove one of those components from the equation, it will slow the ZC down. It has a little more torque than the D16A6, but not much. Where you really notice the difference is 4000 RPMs and higher and at highway speeds. And they are cheap, starting anywhere from $600 for just the engine, to $1000 with the tranny and ecu.</TD></TR></TABLE>
hope this clears some things up....

hey all, sorry im not an EF guy but, when this was said i was curious....

my friend has a wrecked 87 teg with a brown valve cover ZC...and his new car is an 89 (i believe) CRX HF...so...would his ZC be a direct bolt in to his CRX? i was told by a friend the mounts were different but this says differently..thanks
