The turbos used for our cars generally aren't big enough to need nitrous, and the ones that are big enough have efficiencys greater then our RPM band (our 3.8s arent good revvers) So, I would say that is part of the reason you dont see many with NOS. However if you have a T-88 or something, and run outstanding times, I would reccomend it. However, if you wanted to get better response from your turbo, I would go the true and tested way, bore/stroke that mofo!
