Here are some pics of my two stage nitrous set up.
Zex direct port and NOS nozzle system.



The first stage, the big one is activated by a micro switch on the gas pedal and gets fuel from the same tank but is supplied by a seperate pump and filter with their own regulator.
The second stage, the small one is activated by a button on the steering wheel and gets is fuel from the engines supply. Tapped right before the fuel rail.
