You need to select your injectors based on the amount of fuel you need. For that you must estimate your target horsepower. Your compressor's air flow and desired manifold pressure will come into play.
Too small of an injector, and you are going to have to run too high of a fuel pressure to compensate. Too big of an injector and you will turn the pressure down and have poor idle characteristics.
