I'm getting ready to order a nitrous kit. I'm trying to decide between the zex 125 or the nx 150 plate system. I'm an automatic(soon to be stalled). I want to know what kit would be the safest to run on my car. 98 gt2v full bolt ons pi swap stage 2 cams. Will running a eddy jr intake help from blowing my intake incase a backfire? Also anything I should add for my kit. I'm thinking I'm gonna get a wot switch. Window switch to run 3000-6000rpms. Blow down tube. Bottle heater. And pressure gauge and line purge. I'm open to any advise or suggestions.
