congrats on the LT1.
I have a set of 38#'ers sitting around I can get rid of for a decent price. before replacing any injectors, you will need to tune the PCM accordingly.... being a '93 tuning is alot harder than the 94+ cars.
honestly, you want to pick up some power, get LT headers (Pacesetters can be had pretty cheap) Off Road Y-Pipe, cutout, 1.6 RR's, CAI, and then get a wet kit.... make sure when you do this to replace your fuel pump first... if you do want a wet N2O kit, I am thinking about selling mine and I will include ALL safety equipment for it that will ensure that you will have years of fun with N2O
