As far as ECU goes. If you have a DPFI (2 injector) model Civic, you will have to convert the car to MPFI (4 injectors). I will just explain the cheapest and easiest way to do this swap. It would be to get everything in the car, keep the car OBD0 and do the MPFI conversion. Get a PM6 ECU (CRX Si/Civic Si/Civic EX) and D16a6 distributor. Also, if you can afford it, I would get either a y8 or z6 intake manifold. You can use the injectors from the 92+ civic manifolds and you won't have to wire a resistor box in. This way, you will only have to run 4 wires into the engine bay. If you convert to OBD1, that is just extra work/wiring, and more money.
Just shoot me a pm if you have anymore questions. Later.
