Hello, I got a guy that wants me to help him swap his motor on his buddys car. He found a d15z1 for 200 bucks with ecu he wants to put into his eg coupe. it has a d15b in it right now. reading about this swap it seems like a really goofy swap to do. people do them the other way around all the time but never replacing a d15b for a Z1. I geuss theres a wideband o2 on the z1s. anybody know how to wire that sucker and anything else I would have to do?

 

Is he putting in a California motor? Or has he verified a 5 wire O2 sensor?

 

If it is a 5 wire I could send you pictures of my vx wiring to help you out.
