One myth to put aside is Nitrous does not kill motors. Hp shortens the life of a motor. Whether it be turbo, nitrous, or wild compression and a wicked cam. HP puts added stress on parts regardless of the method you use to make it. An ill tune will kill any motor, including an N/A application. Blaming the death of the motor on the bottle is like blaming a murder on a gun.Nitrous makes HP, if your parts can't handle it, don't play with it. There is a limit for each part in your motor. If it is stock, you can run more nitrous until you reach its limits. If you have heads, cam, stroker, you are at the block limits right there. Add 150 hp of nitrous, split the block and blame it on the nitrous. Run 50-100 shot, premium fuel, and follow the directions EXACTLY and you'll be fine. I would be more afraid to run 100 shot on a stroker than a stock motor.
