I have recently come across a fogger style lt1 wet nitrous kit for a very good price. From what I have gathered from searching:

1. the fogger nozzle will not work even if screwed into the air cleaner above the tbi unit because of poor nitrous and fuel distribution.
2. since the tbi runs on lower fuel pressure than modern efi, i will need either a different fuel solenoid or a different fuel system

first, is all of this correct? second, could I simply buy a nos tbi plate to solve the injection problem? third, would it work better to change the fuel solenoid to one made for tbi fuel pressures or simply install a separate fuel system with an lt1 pump? and finally, are there any other problems I will face that I have not yet taken into account?

for the record I have a 5.7l LO5 TBI with the stock fuel system and i am looking for around a 125 shot of nitrous.

 

well you are correct about the nozzle aspect, but not the fuel part. To convert this kit, all you will need a TBI spray plate, and the only difference between an LT1 kit and a TBI kit, or any kit for that matter, besides the plate is the Jetting. All you have to do is check with the company of the kit and see what the proper jetting for a TBI unit would for the given HP shot. Also dont forget about all the safetly equipment and precautions that you'll need with nitrous.
