all depends on what kinda kit you are looking for. how big of a shot. The holley sniper kit is a nice kit has jetting up to 150hp shot. also it is a wet kit which means you add gas aswell as nos so it is safer for the engine internals. now for whats wrong with this kit. plastic nos bottle mounts. not nhra aprroved. it also doesn't come with a blow down tube. the solinoids are small but they work. its the kit i use. the power shot noskit is very good aswell. the edelbrock kits have nicer solinoids in my opinion. whatever you do get an adjustable wet nitrous kit. you can't go wrong with juice. well unless you squirt to much.
