i have a 94 gsr in a 89 civic si hatch it in and ready to go i just need help with the wiring im using a gsr ecu if its possible if you guys can direct me to a web sight on this if someone has it done thanks alot

 

Hey, were did you get your motor from? I'm doing the same except it'll be for a 91 CRX si. I haven't gotten anything yet, but still looking around for parts and info.

 

Try http://www.hasport.com they have the wiring pinouts for the ecu's. It's gonna be a tough one but with a little work it can be done. You'll need to buy an ecu wiring adapter or make your own since the GS-R ecu won't plug into your harness.
