wondering if a jwt ecu from my recently totaled 96 se-r hks super drager exhaust and placeracing intake would work on a 93 g20 before i buy it. I want to be a proud sr20 member again

Won't work... '93 G20 is OBD-1. '96 SE-R is OBD-2.

BUT you might be able to get JWT to either rework or exchange it. Talk to 'em.

Or you can make an adapter to run the obdII ecu with your obdI plug.
