n2o kits really went down in price. You can buy a full zex kit for the g35 for around $650 you will need the gauges which will be around another $200 (AEM wideband a/f is best) If you have a shop install it you are looking around $1200. IMO n2o isn't worth it. You het about 10-12 shots at 75 shot out of a 10lb bottle. The bottle costs $50+ to fill every time. Save up and get a supercharger.

 

I ran mine with a 75 shot at the track best time was a 13.2 at 105. Went back two weeks later with a new motor and a 100 shot ran a 12.8 at 112. The clutch was stared slipping on that pass.

 

the last time i ran at the track i ran a 14.5 at 92 but the DA was 5200 im going on sat i hope to run a low 13
