I have been running a 75 wet shot for the past 9 months and had a 75 dry shot for 8 months before that on a JDM B16 with stock internals. After all that I just now am replacing 2 valves. On my next project I am going to build a turbo motor with a large turbo then use the nitrous on a pressure switch to compensate for lag. Anyways if I'm going to race then I'm using nitrous. That is how my car is set up and that's the way it's going to run. RUN WHAT YA BRUNG.
