Yeah it is. The engine was built to handle 500 HP sprays of nitrous should I choose to do that. It was built to run N/A. My kit can be switched over to a stock engine in a matter of hours and be zooming down the road again.

Nitrous isn't expensive. Costs me $12 a fill for 10 lbs of nitrous. A fill kit to transfer from the mother bottle to 10lb bottle is the cost of a 12" -4 nitrous line. Bathroom scale weighs the bottle.
