Honestly, ive ran Nitrous cars b4. Im goin Turbo on my S2K, jus waiting on the kit. Nitrous is okay, it does require some precautions, like goin one step colder on plugs and I dont know about S2000s, but my Neon R/T when you hit the rev limiter it was a FUEL cut off. This is bad Ju Ju with Nitrous. So I hooked up an MSD DIS II and set the Electric Rev limiter 200RPM below the factory one. I was running the venom kit and it was fully programmed. I dont know anything about the other kits. But with Nitrous, youll only as fast as the bottle is full. Once its empty you back to where you were. S/C and Turbo are always there, so that is the route im goin.

When I did my nitrous kit, I didnt feel the 25 or 50 shot that much, but really noticed it when I did the 75shot which was max for the neon. While nitrous is fun. Its something to think about b4 getting into it. I researched alot and wanted it done safely. On the dyno the A/F wideband reading with the venom kit was excellent as it proved that it added the proper amount of fuel to prevent lean condition. YMMV.
