I have a 95 G20 with the obdII ECU. It also came stock with the low port engine. I am halfway through swapping my JDM high port engine and have read that the OBDII will not work with this engine. Is this true? I hope its not. If anyone can enlighten me i'd appreciate it. thanks again.

that's a good question. I am doing the same thing to my '95 G20 (I thought 95 came stock with the high port - my JDM motor looks like it's low port? Maybe I'm wrong).

Anyway, is thier ECU issues when doing the swap? :confused:

No, it will work. Make sure you swap all the sensors off your old engine onto the new one, and you will need to extend a few wires. However, you will not be able to use your egr. If your state has a visual inspection, that may be a problem. If not, you should be fine.
