Next retarded question
I've never run nitrous, but going from memory of what I've read, etc........ You'll need a fuel solenoid & a nitrous solenoid, an arming switch, a bottle with valve, a "trigger" switch (usually on the linkage, to activate at WOT), the associated plumbing, a fuel system that can absolutely deliver the extra fuel (probably an electric pump & large filter), & a fuel pressure gauge would be nice. I've probably forgotten something, but I'm sure somebody else will ring in. The only person I ever know who ran nitrous did it on a stock 302 in a Ford Maverick. I think he said "I broke two piston rings, but it was worth it!"
