    90-91 PR4 would be butter
    90-91 PM6 (Si) chipped would be butter

    as for wiring, its a plain + simple DPFI->MPFI conversion.

    the PR4 you seek came in the 90-91 Integra LS and GS. You do NOT want the 92-93 PR4 that came in the 92-93 LS and GS integra.

    The only reason why a PM6 chipped with PR4 fuel and ignition maps is superior to a PM6 is that the cars are electrically wired subly differently. The PR4 has an input for power steering control and a standalone AC/AC fan controller. The PM6 has an input for ELD, controls AC on its own. Very small subtle differences, but in certain situations important nonetheless.

    If you can't find a PR4 on your own I have a couple sitting around.
