    What concerns need to be taken into consideration when swapping a JDM B18c into a 92 Hatch Si rather than a USDM B18c?? I thought i read somewhere that some wiring has to be done because plugs dont fit?? Would it be easier to get a USDM motor instead??? Any opinions or suggestions would be great

    98% of the time, the easiest method of putting a motor into a car is to use your stock wiring harness.

    add the wires for the knock sensor, and iab, and you're done.

    if you need plugs (ie, the plug ends) the jdm harness plugs will work fine. the difference is that the jdm model is right hand drive, and thus, the plugs won't reach correctly, as its fed the opposite direction from the firewall into the engine bay.

    even if you go with the usdm motor, id still say use the stock z6 harness, and add the 2 above mentioned sensors' wiring.

    ok that helps, i was planning on using the z6 harness but didnt know if the plugs were the same. Now you said the plugs wont reach correctly?? Does that mean i have to extend everything or a select few??

    on my usdm b18c1, using my stock d16z6 wire harness, the only things that didin't reach were the oil pressure sender and 1 of the 2 distributor plugs. i simply moved the dist. plug harness holder thingge (the metal bracket that the plug attaches to) and it reached- but the o2 pressure sender i had to lengthen.
