I have a Zex nitrous kit with JLT cold air plumbed and ready to go. Kit includes "Full" polished bottle, purge kit and the JLT cold air kit. I mounted this on the car and got it tuned. Then the wife bought me a turbo kit, so it came off. Never used after it was tuned, that's why the bottle is full. I have a blow down tube brand new in box that I will throw in as well. $500 or best offer for everything.
