[nickdutch]

what suporting mods for nos would i need i alredy have a few things done thinking of runing a small shot like 50 or 75 shot just for track days

I'd say put your money else where man. Nos is a bad idea if you ask me. Upgrade your turbo or something else that will be there all the time. For the amount of money to make this work properly, spend the money else where

These days, a lot of dedicated drag racers use a small shot of NOS to help spool up their huge turbo off the line to eliminate turbo lag, but as for track days, I'll have to agree with cschepp - spend your money elsewhere.
If you wanna make your car perform better at the track, try upgrading your brakes with a better setup like the Brembo calipars and rotors off a R33 GTR.

Nitrous Oxide would be nearly useless to you on a track. Like RB30DET said, it's all in the brakes. However, the best mod is the "driver mod" if you want to go fast on a track.
