Hey all,
I've come across a DOHC ZC for cheap cheap and am considering picking it up to replace the Y7 in my '89 CRX.

I've done a little work to my Y7 and it's running @ about 12:1 CR and I've got a delta 272 cam.
Thing is, I'm tired of the lack of driveability on this frankenmotor I've assembled, am having a hard time tuning it, and am afraid that it's not all that fast.

So, would the ZC be a decent swap? From what I understand, it will just bolt right up to everything I've already got (minus IM) and will even run off of my chipped PM6 ECU. I'm also at the point that whatever my next buildup consists of, it will eventually be turbo. I want to build a very driveable motor that will get my car into the 13's.

any thoughts? side by side how do DOHCs compare to 1.6L SOHC non-vtecs?

I have a D16A1 with ZC cams and I've smoked plently on y7, a6, y8, and z6. Im preping up my turbo setup for about $1000 and am looking at maybe 250whp.

Well, ill outline all the zc's and then the y8 for comparison

JDM DOHC ZC: 135HP
USDM DOHC D16A1: 113HP
EDM DOHC D16A8/9: Not too sure

USDM D16Y8: 127HP

there were 2 ZC's, the carbeurated and FI, the dual carbuerated ZC stood at 108HP. I'd say the ZC has a lot of potential myself, it has a low comp already at 9.3:1 on both the US and JDM for sure, with flat pistons on top of that. It's got decent sized ports, My personal opinion, get domed pistons and a set of rods, up comp to 9.5:1 or so and boost it, it love to see that!

The main difference i saw between DOHC B's + ZC and the SOHC Y motors was the port size, it is a bit bigger, than the SOHC, and it would explain the power gain.
