    you will need aftermarket mount kit (like Hasport) and shift linkage - you will need to use the HF engine wiring harness and do the wiring changes to it

    But as far injectors can i use the ones on the d16 motor or will i have to use the ones off the crx hf. Also since im converting it to obd1 i was told i needed an obd-1 distributer is this true?

    you can use the D16Y8 injectors - you just need to remove the injector resistor box from the system - you will need OBD1 distributor

    Thanks also one more thing the obd-0 to obd-1 one harness that i have doesnt have the extra wires for the 4-wire o2 sensor. Is it possible to run the car with out the 4-wire o2 sensor.

    I dont think u need aftermarket mounts and shift linkage
    They are using the cable tranny so shift linkage and mounts should be the same, as long as the driver mount and bracket is moved from the old motor.

    As for the O2 I dont remember what position's the wires go to the ECU but there is an O2 heater and an O2 heater sensor. The O2 heater needs the same voltage power source the injectors have.

    When I swapped a b16 into my CRX I totally overlooked the fact that I had high impedance injectors (it was an OBD1 B16 running OBD0 electronics) and a resistor box. Car actually ran fine except idle sucked, I guess 02 correction was enough to make it run okay. I felt really stupid when I finally figured that out

    Anyway, I don't think there's really anything that needs to be removed on the y8, just need a hacked OBD0 ecu to activate VTEC right?
