The key in doing what your title says, is to use a US OBD2 (96-01) INTEGRA engine harness. It will directly plug n' play into your 92 Si (minus a couple plugs that you won't use anyways). And you can retain the use of an OBD1 ecu too.

Thats it.

like katman said, its easiest if you use an integra obd2 engine harness because it will plug into your obd1 chassis harness at the shock towers. then you need to wire in the secondary butterflies and knock sensor. since your car is a '92 and an si it is prewired for vtec, so you don't have to worry about that.

that would be the easiest way to run it with an obd1 ecu. if you want to use an obd2 ecu then it gets more complicated. you'd need a conversion harness and would have to wire in some more sensors like the secondary o2, the crankshaft fluctuation sensor (CFK), some evap sensors, i'm not sure what else. if anyone knows how to actually do this to pass smog please share.
