If he was running this on a ford, then it must have been a " ALL ford EFI stage one kit." Do not worry this is a good kit, All nx kits are wet kits and have the best nozzle delivery systems of any brand. When nx says that you have a 100 shot then belive it. They are closer to true RWHP numbers than anyone else. The only thing that makes this a ford kit over an import kit, is a few misc. fuel fittings. I sell every brand of nitrous kits made, and NX is the only kit I would EVER run on my own car. You would be safe with a 70 to 100 shot. Remember that a NX 100 shot is like a NOS or ZEX 150 or 175 shot.
