yeah you should definitely have gotten a wet kit. I like NX, but its really personal preference.
bigger injectors, vafc, etc = overkill
colder plugs = smart
NX makes an fpr safety switch, its for people who want to be extra safe but whether or not you should bother with it is really up to you. I think its unnecessary, but its still a good investment. basically if your fuel pressure drops below I think (?) 44-46 psi then the fpr safety switch will disarm your nitrous to keep you from running lean & detonating.
and if you run a wet kit, then a 75 shot will be fine. that's what I've been using on my 4 banger for almost a year now
