I called a shop about he zc engine and he said he's got the SOHC and DOHC versions of the zc engine. He said the sohc makes 125 hp and the dohc makes 137? I thought there was only the dohc zc which made 130ps and the sohc version was the 108hp si motor we have here.

I thought the USDM DOHC ZC was 118hp and the JDM was 130hp

There is no USDM ZC. The JDM DOHC ZC is 130hp

I'm pretty sure there was no US dohc 4g civic. The best they sent was the sohc 108hp 1.6L Si. I found a link claiming the jdm zc engine pops out 137 bhp, so its true. It didn't say anything about their sohc version tho.

The USDM ZC is in the 88-89 Integras hence why a lot of parts come from that engine

from what I understand, "ZC" is a generic term, as the SOHC (D16A6) from the 88-91 Civic Si's is also a ZC, as is the DOHC JDM engine of the
same vintage (D16A8 & D16A9). The Integra units are also ZC's (D16A1). As far as horsepower goes, it depends which references you read,
and which market the engine came from.

yep, i found another site claiming the dohc novtec "zc" has 130bhp. So does the old integra zc's have the same enige mounts as the 4g civic?

gregv

nope, but the Integra unit does drop into the 3G Civics. You have to get the JDM unit to use the stock 88-91 mounts, transmission etc.

ZC is ONLY the JDM one.....all others have a different block code D16A8 for Europe with a Cat D16A9 for Europe no cat....the JDM has ZC stamped as its block code.....ZC is not a generic term....

gregv

that makes sense, thanks for clearing it up.

I think the USDM ZC(D16A1) only has 118 hp...not really worth putting in if you ask me...

at the end of the day you still drive a 4th gen w/ a zc swap
