You'd have to redesign the fuel system on the car to one that can support the fuel pressure a fuel inejcted system needs and build your own custom wiring harness to support the engine or put carbs on the B18C1.

Carburated cars usually only require <10lbs of fuel pressure and don't use a fuel return line so all of that would have to changed. Also, with no fuel injection currently in the car, all the wiring harness would have to be custom built to support it. Wiring for all the sensors, injectors and whatnot would have to be added, along with the ECU and all the wiring and such to support that. It can be done, people add aftermarket fuel injection systems to muscle cars all the time, but it won't be simple. If your serious about doing it, I have a complete GS-R in-car wiring harness that came with my swap (not the engine harness, but the one that's physically in the car and connects to the ECU) that would probably make your life a lot simplier (at least give you all the plugs you would need). I'm kinda saving it for a goofey Honda powered dune buggy idea I've been kicking around for a few years but will probably never do it. If your interested, drop me an email (elvis312@hotmail.com).
