    Alright, so this winter I am taking my old car back, from my dad, buying him a new car.
    So Im going to start a new project.
    I plan on doing a b18b into the 97 civic ex.
    Full swap from hmo.
    What i need to know:
    1) Will the complete changeover from hmo be everything i need?
    2) I want to run obd1 for later tuning, what do I need for this task?


    I will purchase the complete changeover as obd1.

    get the swap as an OBD-2a
    it will be easier to get everything to plug in, you wont have to dick with swapping plugs and shit (just have to lengthen a few wires)
    run it OBD-2a for now
    when you decide to go a little more crazy with the tune if you really want to run it OBD-1 then just get a conversion harness for the ECU and an OBD-1 ECU

    the complete changeover should have everything... not 100% sure about the mounts for a 6th gen though [​IMG]

    What would I have to do when it came time to change over to obd1?

    Besides the conversion harness?

    no
    i have an OBD-2 (00 spec) B18C/R in my sol running off an OBD-1 P28 (chipped)
    im using the ITR dist, the ITR injectors, and everything else... i had to swap a few of the OBD-2 plugs onto the OBD-1 harness i am using
    but i am using all of the OBD-2 equipment and it runs perfectly fine off of an OBD-1 ECU

    by going with the OBD-2 B18B you get a newer engine, with newer components, and you wont have to hack up your harness as much (you will have to lengthen a few wires)

    to run an OBD-0 car as OBD-1 you would eed to convert everything over to OBD-1 and add all of the sensors that OBD-1 looks for that OBD-0 doesnt
