i seems like you have the answers to everything, what exactly are you asking?

 

shooting nos into your fmic to make the air cooler and denser isnt going to get you that much more hp! maybe like 10 hp! so you would like to spend like a grand for a nos kit and like 40 bucks every fill up to not get the most out of it? like greddy civic said go with direct port. it can add 150 to 250 hp or more.
