I have and have done an OBD II swap and you have to do nothing with the oil sending unit WTF is he talking about I guess that is why he sells motors and doesn't install them. All you need to do it get a 96 or newer motor with ecu and you will be fine everything else is just plug and play though you will have to run a few wires vtec solnoid, pressure switch, IAB, knock sensor and you also need to get a drivers side motor mount from a 92-96 prelude and use it also.
