I've got a early '87 TurboII (low impedance injectors) and I am installing a '87 jspec engine. I've read that the wiring harness is different, so is my old wiring harness a direct fit on the jspec? Are the emission controls the same? If not what is the difference? Is there anything else that is different on the jspec than the aspec?
Is there a web site on the jspec to a aspec swap? Any other differences in the jspec from the aspec that I have to change/address?

 

no

 

Umm I think the Jspec harness is reversed/mirrored since the passenger floor panel is where we sit.

That's what it looked like on my half cut Jspec harness that came on my block.

 

No What!! Are you just posting "No" because you don't know the answer or do you actually know something. I'm sure many people have been down this path before and ran into this problem(s). I've installed a 13BT in a car that was not an RX7 and used a Haltech E6K, but this one is in a '87 RX7 and has to pass emissions ,and I want to swap things out when I have both engines sitting next to each other with as little hassle as possable.
