Re: D16 DOHC?
I just did a quick search, and apperently it's the German? Version of the ZC?
You can put that head on, but it won't bolt right up. Oil passages are different and a few other things. I hate saying this but "Search Hond-Tech". So guys have done it before, but it's not easy and sometime can get messy!

Re: D16 DOHC?
d16z5 is the last genaration of the dohc ZC that came in the EDM ED9 90-91 crx. there are also many more generations of the dohc zc. d16a1 (usdm integra?), d16a8, d16a9 (edm 88-89 crx). I think the d16a8 is what you refere to as the brown topp. there was also a doch zc in the 1.gen edm crx, but i don't know what it's called (zc1?). there are many small diffreces on the diffrent dohc zc's (IM, ExM, main girdle, o2 sensor, ecu++), but i doubt any of diffrent doch heads will bolt on to a sohc block..

That is where you, and everyone else in Honduhland, is wrong. Fits just fine on the EW/D15A engine blocks.

That engine won't bolt into your era car. The mounts, the bellhousing pattern, are different.
Trust me, bro, if you have a variant of the USDM D16A6, youhave the best flowing SOHC D-series head. Stock out of the box, the DOHC ZC head flows better, but if you go with o/s valves, a good valvejob, and some cams you'll knock the DOHC ZC out of the water.

Re: D16 DOHC?
Actually, adjusting both camshafts on a DOHC setup gives minor fluctuations in power, all things considered. Might be worthwhile if you are a NA sissyboy, but...
For a forced induction application - you are on HMT for a reason, I ASSume? - there is no reason you can't hit 400 whp on one of the popular stock D-series heads - DOHC ZC, D16A6 (aka your Z2), D16Z6, etc, with common as dirt T04E compressors, all within the sensor range of a GM 3 bar MAP sensor. Brute force induction of substantial quanitities of airmass get you there, not twiddling fancy adjustable cam gears. Your knock limit on (US) pump gas will be in the 350-380 whp range, and fiddling cam gears won't affect that worth mentioning. So - why fiddle twiddle? It makes no sense :P
