mpfi. 92-95 is obd1. so it depends on if you're staying d series or going b series. if staying with a d, then use a d series one, if you're going b, then use a b series one.

You're already mpfi.
To change to OBD1 you will need a distributor, 4 wire O2 sensor, jumper harness and an ecu.
If you are running the stock exhaust manifold you need to plug the holes where the O2 sensors are because they only sample from 2 cylinders each. You will need to add a bung for your O2 sensor after the collector or where all 4 cylinders meet.
