    what's up everybody...I need some help on my engine swap I have a 91 civic that I want to swap a D16Z6 engine into. So far my part list is this;

    D16Z6 engine complete
    P28 ecu
    90 si tranny
    90 si resistor box
    vtec ecu jumper harness
    92-95 engine harness

    My questions is,

    I know I have to switch to obd1 to do the swap, but can anyone tell me or link me to a site that would show me how to do the switch without using the resistor box?

    I also would like to know what others parts would I need to do this swap?THX GUYS.

    +1 on just shelling out the money for Rywires work.

    It will make it plug and play, which is exactly what you want if/since it's your first swap.

    what I mean is performance wise what would be the best set up, keeping in mind I would be using a 90 si 5spd trans.

    thxz Blanco, this is going to be a street car but I want it to be a respectable street car. I checked out rywire for the engine harness but they want like 300.00 dollars do you think that is worth the money?

    i'd go with the oem clutch and axles, if not honda oem, then autozone or equivalent. i wouldn't upgrade them until you need to. they can take a pretty good beating from the z6 before you need to spend anymore $$$. good luck with the wiring, you should take pics and post em up!

    Obd1 Resistor Box

    If Your Running Obd1 I Thought A Resistor Box Wasnt Needed? Just De-pin The Resistor Plug And Plug The Wires Into A Dead End Plug From An Obd1 Harness

    oe clutch? why not upgrade to a stage 2 or 3 and liteweight flywheel while you have everything apart would be a better plan

    thats true i guess...saving money's always a good thing. but definately honda oem rather than an autozone or advance brand

    ok..so the obd0 to obd1 conversion harness comes with the 4 wires needed for the new o2 sensor...do you just leave the o2 plug on the engine harness unhooked and use those wires?
