That is actually going to be a pretty complex conversion.

probably better to go with an aftermarket DFI if you're looking to just make tuning easier?

Opti needs to be convertered to a 94+ 93 opti/harness will not work on a 94+ ECM and a 94+ opti harness will not fit into a 93 opti. Could be the whole opti swap, cam, timing cover etc.
Oil sender different, need to use 94+ sender or entend harness

93s speedo is not ECM driven, may need to do something with wiring harness ( from the trans to the speed-o, and need to probably do some reprogramming based on if you have a manual or auto trans.

93's are 22Lb injectors, 94+ are 24lbs, need to reprogram or swap injectors.

Not sure what year it changed by TPS sensor and possible a few others changed, may need to address replacing some sensors.
