Here is a complete list of everything I have done. Rywire obd0 - obd1 conversion harness, P28 ECU, re-pinned obd0 harness for obd1 distributor, removed obd0 injector clips and soldered obd1s on, removed the injector resistor box by soldering the 4 red/black wires and yellow/black wire together, 4 wire o2 sensor. That is pretty much it for the wiring I have done, all this wiring was done on the stock 89 crx si harness. This is a list of things I have replaced on the motor: timing belt, tensioner, water pump, plugs, plug wires, cap, rotor. This is a complete swap as I got the complete motor from hmotorsonline. The motor is a ZC Vtec which is the equivalent of the USDM D16z6. Sometimes it starts and sometimes it doesn't. But, when it does run in runs like crap and when I try to give it gas it dies. I checked timing and it is correct. I also ohmed out the coil and distributor and it checks good.
