out car shoppin and i came across a 91 civic Si and when i popped the hood i noticed an LS head on it but when i read the engine code from the block it read ZC the stock Si motor for that year i didnt think youc could put a 1.8l head on the orginal i think 1.5 or 1.6 l block can anyones explain this to me?

 

the ZC isnt the stock motor for that car also ZC's look like ls motors so are u sure about that and also how could u tell that it was an ls head?

 

first of, how do you know it's really an LS head?

 

looks like and LS head to me has the two cam gears on the side and not one lol has the valve cover so i assume i didnt look under neath the cover but it did have to cam gears spinnin

what cars did the ZC come in on both USDM cars and JDM cars

 

All 1.6L D-series engines from Japan are stamped "ZC." There are DOHC non-VTEC, SOHC non-VTEC, and SOHC VTEC ZCs.

The engine you saw was a DOHC ZC, which has a valve cover that looks somewhat similar to a B18A valve cover (there are a few differences though). You cannot use a B-series head on a D-series block, they are not interchangeable.

ZCs came in many, many different cars in Japan, including 3rd, 4th, and 5th-gen Civics, 1st, 2nd, and 3rd-gen CRXes, and 1st, 2nd, and 3rd-gen Integras. Some were dual-carbureted and some were multi-port fuel-injected. As I mentioned before, there are DOHC non-VTEC, SOHC non-VTEC, and SOHC VTEC ZCs.

No engine sold in the United States was ever stamped "ZC." Our 1.6L D-series engines were all stamped as "D16 _ _."
