Nitrous ain't cheap and it ain't just throw a bottle in the trunk... Speaking of the bottle do you have a $200 heater to keep it at 92°? Speaking of the bottle is it less than 5 years old so it's still certified and somebody will actually fill it for you because if it's not they won't...
Do you have the strap down kit for the bottle? And are you putting it in the trunk? Because if you're putting it in the driver's compartment you have to buy a tube for the blow off that goes out of the cab... I wouldn't buy used solenoids as if one sticks especially the nitrous One open... BOOOM!!!... Full throttle switch? Low pressure switch? Window switch? Activation switch? Timing retard?... Nitrous fuel pressure gage? To verify the fuel pressure when and use not at standstill?...
Food for thought...
If you're feeling lucky I'm sure you can get away without some of that stuff... You're very safe "with a well tuned system" using 150 shot... But even that I would creep up on doing a 50-100 and then finally 150 after you figure out your tune.. I would definitely want an AF gauge and keep close eyes on the spark plugs after each pass...
