SEARCH!!! if there is anything about this you can't find in search, then you didn't read all of it.

 

You have some wiring ahead of you if you no only intend to do a dpfi to mpfi conversion but also an obd0 to obd1 conversion. Your looking at wiring in extra injector wiring, a resistor box (unless you go obd1 like your talking), adding wiring for an additional sensor in a mpfi distributor. If you are hellbent on using the 93 ecu, then you will need a distributor from an obd1 car, and you will need a 4 wire o2 sensor, vss issues are going to come up also. The wiring for the O2 will also need to be added. At the ecu you will then need to make a jumper which will basically translate all the obd0 pin positioning so that it communicates with the obd1 ecu and plugs in. If you don't know whats up, your not going to make the car run period. A better approach would be to do the dpfi to mpfi conversion then run it off an obd0 ecu. Control your vtec then with something like a vafc, or a simple msd switch. There are also Zdyne options for 1 wire vtec control. None of this is going to come easy though if you intend on doing it yourself so you better start puttin out more effort.
