What do you want it for? Nitrous is only good for quarter-mile drag racing and stoplight grudges...it doesn't really make your car faster, it just makes it turn in lower times.
You would have to be a rich idiot to hit nitrous every time you got on a freeway onramp, every time you pulled away from an intersection, and every time you wanted to pass...but those are all the times you would feel the power from a turbo or supercharger.
Unless you are only looking to turn in lower times at the drags, I would say pass on the nitrous.
Just my opinion, I'm probably wrong.
