You can call my opinion gay all you like. But NO2 can blow your engine much easier than you think....and even any backyard mechanic could tell if you were running that shit for a prolonged period of time.. I'd suggest a turbo, or maybe a new car...

oh, and insurance surely won't cover anything when they find out you have it, you'll prolly end up getting dropped off your plan. I doubt any inurance company will cover a street car with NO2
