First off I have a '91 DX that isn't fast enough for me (of course it'll never be fast enough) I recently read a post about building a DX monster. ZC pistons, MPFI conversion and SOHC VTEC head swap seems like the way to go. My question is how does the d series VTEC conversion differ than the b series conversions like ls and B20? And also, where can I find a list of d series motors including specs and the model it came in? Ok, last question; I remember seeing a tech article about MPFI conversion but I can't seem to find it. Where is it? Thanx for all your help.
