To nitrous or not?

I had to look up shitload as I was pretty sure it was somewhere between buttload and a large *** amount LOL...
anyways I hear you on that I don't have excessive money to just blow up motors day after day that's why I have all that safety crap on there...
I'm new so be easy! Would you mind giving me some examples of the "Safety Crap" I should run? Maybe like what you're running. Id honestly rather spend a few bucks now than thousands later!!
