Nitrous express 30020 plate system i bought last year, installed on a 2.3 mustang with a holley 2 barrel. Ran maybe 5 bottles through it, switched to turbo this winter and dont plan on using this anymore. I bought the blow down tube for it which is needed for the track and also the purge system for the car. Comes with extra jets also standard 50-300 hp jets, but I bought jets for 62ish and 75ish hp also. Might not be exact but nitrous express assisted me over the phone on what jets to order for those numbers. Ran up to 100 hp jet on the car. Have instructions for it still, comes with throttle switch which was bent to fit car and the lines off the solenoids were also bent to fit the car. System worked great with no problems. Also bought a bottle gauge for the 10 lb bottle. Every part of this system is from nitrous express. Missing the switch to turn on the system and the button for the purge because I put holes in my dash to install them and do not want to look at the holes. Can buy those at most auto parts stores.Also might be missing some small wires and connectors that I have used to install, but you will need more wire anyway because they dont provide you with enough anyway. I included the brake line I used for my purge because it has the fitting on the end of it, can cut the fitting off or use that line, it is bent because like I said this was installed on my car. Comes with everything you see here. Have well over 800 dollars in this system. Bottle will be drained out before shipping obviously just took pics before I drained it to show gauge does work and bottle holds pressure fine. This will be the last posting before the system goes back on the car. Price is bottom line so don't bother with low offers
