So I just thought I'd pick at yalls brains for a few. I just bought a 1985 rx7 GSL-SE for 50 bucks. It has no engine and no title. I'd like to get a 13b that came with the car(sorry I am semi new to rotarys) so I'd like to get a 13b that came with my car from the factory and do a carb swap. I have all these wires in my car now all these harnesses and I have no clue what they're for. If you guys could please help out with what I need for a carb conversion and what wires I do need and don't need. Thank you guysv
