Okay i recently got a o1 gsr shell and im putting a b20 in it for now and in the summer going b20vtec, but what i dont know is what ecu and wiring harness do i need to use for just the b20 right now. ive been told to use a p75 but i dont know witch harness to use for the swap. thank you for reading this and for your help.

 

please help

 

What year is your b20?

You have options, you could just buy a stock 00/01 p75 ecu or buy a conversion harness from 0bd2b-obd1 and buy a stock p75 obd1 ecu/ chipped obd1 ecu with a ls map.

 

its a 99

 

just use the harness and ecu that was in the crv u pulled it out of just to get it running and worry about the rest when u decide to start building it with vtec or whatever

 

Just use your gsr harness and keep your gsr distributor.

 

its just a shell he may not have those parts

 

Then that's what I would get if I was planning on going B20vtec down the road.
