that i have owned! my first Z was N/A 2+2 and i used N20 for about 80,000 miles with no problems! Definatly go with a wet shot only! make sure you use a switch either under the gas peddle or on the throtle cable so it can only engage under wide open throttle. also only activate it above 2500 rpm to avoid any N2o pooling up in the intake. Follow these simple rules and you will love the Nitrous!
