    well you have to convert your harness over to mpfi, or but a conversion harness, but they both do the same thing

    what about the fuel pump? it will handle that setup just fine.

    if the b20z has a knock sensor, don't worry about it. the pr4 won't look for it.

    Yes your pump should be fine. If you can get a faster fuel pump...couldn't hurt. Look into a Si pump and see if it pumps more fuel and it could be a cheaper upgrade. As long as your 91 LS head is complete with OBD0 dizzy/injectors/TB (think TB can be OBD1 too)/etc then all you should need is a OBD0 alternator and your harness converted to MPFI. ECU should just plug in. Cable trans....I would suggest a B16 trans to get a nice jump off the line (but high rpm on highways) If you drive a lot of miles...then a LS trans. B series axles, Hasport mount kit and shift linkage (or modify the LS linkage)

    Well...get a nice transmission then. If you plan on having fun with it....get a cable VTEC trans. It'll rip off the line with a VTEC trans. LS trans is a little lower gear ratio....although its getting kinda hard to get any decent condition cable trans anymore. Check out hmotorsonline.com if you want a good condition trans but plan on spending some cash (LSD would be preferred)

    If your car is already MPFI...your harness should be fine. Just leave the knock sensor unhooked int the block or plug it up with a stumpy bolt (I've seen these bolt plugs on D16Y8's). Use a OBD0 B18A1 ECU (it wont read for it anyways...and its the ECU for your head)
