I found the 2000 gsr engine I needed, but problem is, no ECU. Does anyone know whether I have to have the 2000 p72 obd2 corresponding to that exact engine, or can the ecu be from any 97-01 GSR? This is pertaining to the fact that I'm looking to BAR the engine in my 2000 Ek. Thanks.

 

as long as the ecu is obd2 ur good

 

you're going to need an obd2b p72 since you have a 2000 ek and your original car harness is obd2b. not sure if the obd2b p72's had immobilizer's or not tho.

 

You must use an '00 - '01 USDM P72 ECU, it will have an immobilizer that you will need to have removed and replaced with a dummy chip to prevent a CEL. H-T used to (and possibly still does) have a service where he would do this.

 

soo...two different answers lol. I think I'm going to just call up BAR tomorrow and ask myself, but I do appreciate the answers.
