I have a 99 GT with nitrous before I installed it I researched the hell out of nitrous. As long as you keep the size of the shot down to 75 or 100 and get yourself a good tune you will be fine. If you think that everytime that you are driving the car and spraying all day long, no the motor will never last it is like beating the hell out of your car but a much faster pace. I only spay 75 to my car and it has been in there for four years and I just recently had the bottle filled for the third time.
