compucar has a nitrous in a bag kit...full kit for less than $400...it is a dry kit and has a very simple installation...and can be easily swapped over to another car...it has jets for 4 cyl/v-6/and v-8..definitly more power than the sneaky pete setup...and the bottle and all the solonoids are contained in a gym bag...it is controlled by a switch that plugs into your lighter..pretty cool little system....
