there will be some wiring involved, to get you car to MPFI (multi-point fuel injection), then converting to the ecu to OBD1 if you get a 94 or newer b18. It is a pain to go to OBD1 but in the long run i think that it is worth it so you can run something like hondata (

other things that you may need,
-throttle cable mount (do not know if you actually need this)
-axels
-92 GSR upper radiator hose
-90 Integra lower radiator hose
you are probably going to want to change the timing belt, and the rest of the belts.
The clutch
and the water pump and thermostat.
if you want i have an Excel list that i am using for my b16a2 swap if you want i can send it to you it has everything needed, and you are planning a similar swap it sounds like. Just send me a PM.
Good Luck.
