lol seriously, i've put nitrous on a car in 30min.

Zex kit owns, only problem is, the bottle's always empty when u need it. And around here it's 42.50 to fill it, i'm sure it's more out west.

Turbo kit is a little more involved but thats where the power is at, and it's awsome knowing that every time u step on the pedal, power's there if u want it.
