welcome to the boards man.

not many people around are running nitrous, so you might be hard pressed to find your answer locally. Check out the under the hood

 

yeah its alot of fun but sux once the bottles empty but yea having just a little 50 makes a hell of a big difference its addicting and yeah i think i am going to go with the 80 direct port but after i get headers and other shit till then ill just stick with the 50

 

Welcome - and be sure that your air-fuel is correct while you're spraying, even with a 50-shot. A dyno with a wide-band A/F meter is your friend .

 

The upper limit on nitrous for a stock s2k is about a wet 80 shot with some tuning. Check out the "Under the Hood" forum for more opinions though.

 

what are you doing about timing?
