Simple - NX doesn't give as much of a saftey barrier for the A/F ratio to be a bit rich. You can lean out a NOS kit and get more power out of it without burning anything, but you increase the chances of running into a problem. NOS deliberately runs the fueling a little rich to prevent detonation. NX runs LEANER, closer to the edge of detonation. More power? YES. Feel safer? NO. (At least I don't) I've sprayed just about everything I own(about 14 cars depending on the month
) The simplest and IMO Safest are the ZEX and the VENOM kits - they shut off if the fuel pressure drops out - NX and NOS base kits do not come with any sort of fuel drop off protection. You can destroy ANY motor by not using nitrous CORRECTLY. Most casualties of spray I have seen are from people running too long on the bottle, running garbage for fuel or using it on a engine that was not mechanically healthy.
Just one thing Tricker - how is your setup gonna add 200 pounds? A full 10 pound bottle averages at 24-25 pounds EACH - FULL. A stack of solenoids,bottle brackets and hoses still can't weigh in more than 30 pounds.I count 80 pounds. Even with your ignition boxes - Maybe 90 pounds.
