    Look in the reference section for DPFI to MPFI conversion. It's pretty easy- change distributor, change ECU, add 4 extra wires, then move the head or entire engine over.

    the mpfi harness wont just plug into the dpfi chassis, the swap itself is direct drop in and bolt up, but you have too change a few wires at the ecu, add soo many, and switch a few around IIRC, id use the zc preferably, only difference between the sohc non-vtec zc and the d16a6 is the cam though, which obviously the zc cam is a "hotter" cam, if I was going too do a mpfi conversion, id do it all at once, while motors out, wire everything, then drop motor in plug up and roll
