Internal work...to my engine? Nope...I wouldve only ran a 50 shot. A while back I blew my tranny after my mechanic fuked up my clutch install. He dint put the tranny plug in so all my fluid leaked and my scynchros got fried. Check out my old posts. But yeah...any interests??
Yep this kit comes with different nozzles that allow you to spray 35, 50, 75 shots of nitrous. The autometer gauge just tells you how much pressure is coming out of the bottle. Optimal pressures will range from 750-800 psi I believe. Please read up more info on nitrous if your new to it. Buying things are easy but you have to know what you are getting into.
