    Transmission- B16 has the best gearing, plus it's cable actuated.
    Needed to roll- Axles, Mounts, Shift Linkage
    Needed to drive- harness that will work(don't know much about 1st gens), obd-0 to obd-1 jumper harness for the ECU (if you want tunability and VTEC).

    Should get you started anyway.
    I don't know if this is a bolt in process or what, but like I said, I'm not really familiar with 1st gen swaps

    yeh im bringing my harness to rywire.com, and they will do the full conversion for me to OBD1 for a plug and play harness. im not sure what ecu i should get, i know i need something that will be chippable to dump enough fuel, but thanks for your help,



    if anyone else knows anything, it would be greatly appreciated. :)
