I have two Holtzman 50hp nitrous kits both are the exact same except one has a fuel psi saftey switch on it. they are for twin carb sleds. you will need to find a battery pack or do what i did and use a small 12 volt battery. i did not like the batt packs that came with the kits and thats may be why i cant find them. each kit has everything needed. the bottles are 2.5lb bottles. i also have a one other bottle but needs a new valve, will throw that bottle in with the first kit sold! EACH kit is $325
