i have here is a nos kit that belongs to a friend and was suppose to go to his racing boat. my friend desided not to put it in becouse the motor alone had plenty of power. the kit is complete all the parts are there and unused. he paid $2000 for the kit with out the bottle and an extra $300 for the chrome bottle and bracket. you can go to this website for details on the kit.(http://goodies-speedshop.com/i-1505055-noszle-direct-port-e-f-i-nitrous-system-universal-8-cyl-kit-100-300-hp-w-o-bottle-and-bracket-available-while-supplies-last.html). the NOS kit is garranteed to not be used and like all racing parts, item is sold as is with no warrantee and i am not responsible for incompatibility.
