Wet kit is the way to go (like you haven't heard that already) Stay away from Zex. I've had 2 Zex systems and they both malfunctioned. Plus on the Zex systems running a 75 shot was only giving me 42 at the wheels, before they messed up (stayed spraying). You do know with nitrous you're going to have to drill a hole anyway for a blow down tube. They won't let you run at the track without one. Well in Arizona they didn't, I assume it's the same here.Originally Posted by TRYMY4.0
