... turbo manifold: is the ZC a B or D series? AND...
 

im basically taking a poll because some people say its b and some people say its d because of it s simularity to the d16A1. I would like to know what manifold to install. Thanks guys!!!!
Also, I may want to do a DIY turbo setup on my dohc ZC. From your knowledge, what is the most cost effecient and reliable setup i should do? Thank You very much for your time!

found it to be D

absolutely a d16 without a doubt. D-series.org !!!!

Here is a link for more in depth about the ZC motors; and yes they are D series.

Dohc zc specs,mods, parts list - D-series.org

as the others stated yes it is indeed a d series, but be sure to research the parts list, there are MANY parts that you need to order from either an 88/89 teg, but as for the dist, the 86/87 teg uses a vacuum advance dizzy, but t-belt for the zc is from a prelude si, timing belt tensioner is for a 88/91 crx (the teg will not work)
which manifold? the zc port spacing is different from the dohc vs the sohc( intake and exhaust) the only way you'll get a sohc intake on, is by buying the adapter plate from zcspeed.com, OR you buy an obd1 dohc zc head
exhaust: any d series exhaust manifold will bolt RIGHT up, but mild porting on the exhaust manifold flange may be rquired as the port spacing is shifted about 1mm ,
d-series.org FTW
