Nitrous on an SUV is a complete waste of time and money. Especially on a 4wd. I bought a 4.0 for a reason good blend of power and torque mixed with some cargo room. I am not trying to hate on what you are doing but i see no point in dropping several hundred dollars on a nitrous kit for an SUV with a crappy 4-banger in it. plus what in the Hell are you gonna race against in Alaska? :dunno:
