I have a 10lb Zex bottle sittn around thats driven me nuts, I want to use it. I like my car so I'm not gonna shoot it, but do want to use it to spray the intercooler and purge at night with an led for fun.. Ive been checkn out the sites that sell the kit, and seems a lil expensive. My plan is to build my own by piece'n a kit together and maken my own spray bar. Has anybody out there done this any info would be great!

Just make a foger system. And add a purge vale and get 1W leds.
I think you will need this parts:
cooper tube like 1/4" diameter
purge valve
nitrous valve
Leds 1W and higher, collor you want. I would use 3 leds with blue, red and yellow collors. Use the power of the purge valve to activate. Leds wired in siries.
aditional tubing to route nitrous
steel plates to make a mount for foger tube aka cooper tube
that should be a good start.

Either run a 50 wet shot or sell the bottle and get water/meth injection. Both will give you far greater performance than spraying the ic. You can run a 50-75wet shot easy with a chip and increased fuel pump. As for the water/meth, it will cool the intake temps far better than the nitrous will and alsogive you: below abient intake temps, clean the cylinders, let you run higher octane programs with pump gas, and increase both timing and boost.
