hey i have a 94 hatch with a LS motor in it right now and im planning on swapping in a 94 GSR motor. My question is will my engine harness plug up to the gsr without any problems?

 

yes, but you will need to run vtec, knock, iab wires.

 

???anyone???

 

Yes , but like 2lua said you will need to wire up the vtec, knock, vtec oil pressure, and iab's(but only if you use a gsr ecu). You can also use a chipped p28(92-95 civic ex).

yes i'll be using a gsr ecu. can i use the p28 ecu and still pass somg? i dont think so right? so i'll play it safe and use the p72. If i decide to use my current si engine harness i'll have to wire up the vtec,knock,vtec oil pressure and iab's? but why? wouldnt it just plug right up to the gsr? if i get the gsr engine harness i wouldnt need to do this then right?

 

If you use the si harness you won't have the iab's cause the gsr mani is the only one with the butterflies. You need to use the gsr harness and ecu to avoid any extra wiring.

I'm using a p28 with my gsr, but I don't know anything about that smog crap, I live in Maryland. The emissions station gave me a 2 year waiver when they say how low my car was, haha.
