if you change to obd1 you can still retain the obd0 injectors and resistor box. in order to use saturated injectors you would need to delete the resistor box by soldering the 5 wires that go to it into eachother. whether you stay p/h or go with saturated injectors, you will still be accomplishing the same thing.
the 92-95 h22a and h23 injectors are 330cc. why do you ask though if you can use them? they are too small to run boost with and would probably only be useful if you were putting together something like a ballsy natural aspirated engine with diff cams, pistons, head work, etc.
