I have a brand new ZEX nitrous kit. The part# is 82040. It's for a carb and has the perimeter plate. Comes with jets for a 150, 200, 250 and 300 shot!! The kit has never been bolted on a car and comes with EVERYTHING to bolt it to your car!! The main box holdong the bottle was damaged when I moved but all the smaller components of the kit( plate, lines, fittings, jets, switch, relay etc...) are all in the original boxes. I bought this kit brand new from summit for $620 bucks and then paid an additional $40 bucks for the blow down kit. So total...I have $660 invested in this kit. I will sale everything for $450 shipped to you door!! Thats a steal for everything all new! E-mail me at [email protected] or call 301-395-3921.
