How big a dry shot can my crappy 22lb injectors support.

Going to be getting a nos dry kit and it'll be going on my 93. I know the 93s only have 22 pound injectors as opposed to the 24 pounders that came from 94-97. How big a dry shot will be safe 75? Also I plan on going to ls1 injectors soon, they're 28pounders right? How big a dry shot will these support? Also what kind of accesories will I need to complete the kit, I'm getting a ignition with it so. I'm just looking for the essentials to make it safe. Sorry for the dumb questions I'm new to the nitrous thing.

100 shot max to be on the safe side

You would have to be absolutley NUTS to spray a DRY shot on a stock GM injector. I do not care if it is 22, 24 or 500. The strain that a dry kit puts on the the injectors is tremendous, 75shot requires not larger but better quality injectors. Any time those things can lock up and go lean.I recomend: Lucas, Accel, or Ford SVO. You want that engine to be safe? First priority is to change those injectors.

Thanks for the replies, I went with the nitrous works wet shot so I won't have to worry about my injectors.
The kit says I need a higher output fuel pump, any suggestions?
