87_2nd_gen_rx7

Ok well as we all want to go fast i want to add NOS to my car, but i have been to some other threads and ppl say not to. Well i dont know how much i could run and also should i do slight mods to my car first.
So the two questions:
1. how much should i spray and would be safe?
2. should i mod my car?
i already have a header and intake and im getting plugs and plug wires.

Any amount is fine. Just make sure you put the bottle somewhere where everyone can see it.

I wouldnt be thinking about nos yet if i were you. Whats the mileage and comp #'s on your engine? If you are positive you engine is healthy with strong numbers then i guess you could install a nos kit but its only going to be a matter of time before you pop an apex seal or something. Try some other kind of mods, your gonna be happy with nos for now till you blow your motor and regret ever thinking about it.
