    so basically if i have a 88-91 dx and want to do a zc swap. im going to need to do a mpfi swap first. which ecu do i use. do i use the zc ecu or do i need another one? i dont need any mounts or brackets or make any frame adjustments like when you do a b series swap?

    if you use the zc tranny you will need new axels, if you use your dx tranny then you can use your stock axels. The MPFI wiring took me about a day, however it took me 4 days to complete the swap on my car as i was waiting for parts from honda. you can use your stock mounts and there are no frame modifications needed for this swap...

    If it is a DOHC yes (use's halfshaft,like the B and H), but if it is a SOHC you will be ok.

    that "lovely diagram" happens to be wrong - from the distributor, the CPS wires are blue/green which goes to C1 and blue/yellow which goes to C2, the TDC wires are orange/blue which goes to C3 and white/blue which goes to C4
