I want to put the purge off the n20 somewere cool, but that it wont harm others or their cars. Anyone have a place.

Why not? It would be a good time. Tell some one to stand by a certain spot and shoot them! like in 2f2f when he does it in the skyline...Ok sorry.

I say, where your washer fluid comes out or if you wanted to be original purge through the side mirrors that would be kinda unique. thats just my 2 cents

Through the hood is always cool. There is a company out there DynoTune.com (as well as proably other) that sell a V-end fitting so that you can plume one line and Spray in a "V" patern. I cut a hole in the center of the hood between the window washer sprayers, as my zex kit include a short hard line and I was to much of a hurry to wait, drive back to the store, buy braided lines and a exit fitting.
By the way that postion work out find as the is a oval shap cut out in the braces from factory.

You can do anything you want. put in a T, or snake it somewhere. I used 3/16 brake line and when I did my friends car. Purged it threw the hood scoop on his accord. Looks cool. I'm going to purge mine threw my grill with a duel line.

purge next to ur muffler? wouldnt that be interesting...

how about do it just like the skyline, get the z3 fender, mod the vents so it wont freeze and purge them on both sides...thats gonna be hot

how bout pointing it down at the ground in front of the tires, if it works right it will look like ur smokin ur tires
