    I was wondering if anyone could tell me the exact differences between 90 and 91 cars. My friend keeps telling me to get a 91 because they're apparently better than 90 cars. Another friend of mine says he doesn't touch 90 cars because of "all the little differences" I drive a 90 GSX for clarity

    Transmission, oil cooler setup, spline counts on certain shafts, wire harness on the cas vs a plug on the newer 4g63, completely different throttle body and isc and tps sensor, different ecu pinout. Thats about it, neither are "better" just different.
