My plans are to have a mild build d-series block that will be turbo'd around 15psi. I was wondering what motor choice would yield more HP in the end. Whichever motor choice I go with will be converted to OBD1 tuned on Uberdata.

D16a6 block // D16z6 head (aka mini me)

Out of those 2 you have here, I would take the complete Z6 block and head because it will yield a lower compression which can take more boost because you can tune it easier. The ideal setup for d-series turbos is the no-tec setup. You take a vtec block and put a non-vtec head on it. (no-tec) Which comes to not having vtec and a compression ratio or 8.x. With no vtec to tune and a low compression ratio, you can crank up the boost.

So what would you suggest? z6 block with a6 head?

 

i would say neither completely stock, since the ZC head flows more than both of them. but modifed the d16z6 is hard to beat and stuff is getting cheaper and better by the day.

 

good luck finding any info about "no-tec" im gonna try it tonight ill let you know how it works. the z6 boots pretty good it can handle about 13lbs all day with a zdyne and 450cc injectors but the head doesn't flow all that great
