there are other options. easiest being to study up on the wet system so you do understand it. there is reading material out there. it is actually a better system to use for the engine as the fuel is added directly rather than with a dry system which compensates in other ways.
however, your best bet is the 750$ manifold system. which injects inbetween the upper and lower intake directly into the ports, right above the fuel injectors. this is almost the same as injecting the n2o through the fuel system as it enters at roughly the same spot. it is the safest system and the most powerful. (other than some of the top dog systems and their direct ports)
it is also nice because you can hide everything and look less like a power adder than someone with a normal dry or wet kit. i personally wouldnt care and would want a purge valve cause i think they are cool as $hit, but that is my opinion. ifyou want to creep up and not tell people what you got, than this would be perfect for that.
regardless, you can hide it or show it, just wanted to give you a couple more ideas. i almost bought a manifol system but the store had it on backorder for over a month and i decided to rebuild the motor with my cash instead after all of that.
perhaps in time,,,,,,
