The D16A6 is the best D for building up (due to it being a bit stronger then the rest bottom end wise). The Z6 is great as well. This post is a bit too general, their where various D15's and D16's built both vtec, and non-vtec and their was also the DOHC D16(ZC). Wich two engines in specific are you trying to compare?
