hey hows it going...i wanna put a lil juice on my car just to give it a lil more speed...and i was going to buy a zex nitrous bottle off my friend for like 50 bucks...and i also heard zex is one of the safer nitrous companys...i dont want anything too crazy cause i dont want anything bad to happen to my motor so i was thinkin about just going with a 75 shot...and anyways i was just wondering what everyone thinks if the zex setup and also if i have just the bottle what else am i going to have to get? i know ill have to get a purge kit and bottle brackets and what not and also colder plugs but what else will i need? thanks for the help!
