Here is what i have I bought a 87 RX7 and the original motor was pulled they gentlemen told me he had a 89 jspec motor put in the car how can i tell.

Jspecs are also turbo so if the car was originaly NA and is now turbo its a Jspec swap.

check the fuel rails...if the pulsation dampner is on the rear of the secondary rail, the its J-Spec, if the regulator is on the rear of the secondary rail, then its north american.

Or just look for the turbo

In J-spec motors the fuel flows the opposite way......don't ask me why.
