I have 94' dx with a JDM D15 in it, but I just bought a GSR couple days ago... I've searched an stuff but no real clear answers on wiring were to be found... It's OBD1 Motor and my car is OBD1, does this mean that the engine well just be plug an play..?? No rewiring necessary..?? I'm already wired for vtec, knock, ect... Only thing im sorta semi-concerned about is i heard something about a crank sensor maybe needing to be plugged in or something..?? Anyone done this swap, or kno if i'm not gonna run into those type of problems..?? Thanks..

 

I have an OBD-1 SIR-G (B18C) and I used the stock harness (CX). I only had to wire up VTEC and o2 sensor. I eliminated the secondary butterflies and the knock sensor by running a chipped P28 from Kenji who is a sponser on this forum.

 

It will plug and play. OBD-1 motors don't have crankshaft fluctuation sensors and OBD-1 ECU's can't read input from them anyway. You may have to run one wire for the IAB's.

 

I heard like 92-95 gsr's i wont need to wire anything but 98's well also work but something bout 96-97.... anyone kno sup wit that?
