So I dont know a whole lot about nitrous but with wet shots, do you still have to upgrade your injectors, pump, and/or get a regulator? A wet shot has a nozzle that sprays both nitrous and fuel into the engine, so as long as you are spraying enough fuel, you wont run lean and cause the engine to blow up, right? Do you only have to upgrade injectors and all that on a wet shot if you're not spraying enough fuel for the car to need?

 

After spraying, pull over and check your plugs. If they are white, you're lean. That's the best advice.

 

on the beta motor, depending on the SHOT of nitrous you use(not shots) all you really need is a GST fuel pump to be safe, ive used a grand cherokee fuel pump also, but dont remember the size anymore, so a GST pump is probably your best bet



no need for injectors and other stuff, the fuel side of a nitrous setup adds fuel needed to the plume



now if you were going with a dry shot then yes, you'd probably need everything you've mentioned
