Hi, right now I'm thinking of getting a 75 shot nitrous kit for my G35. I'm trying to figure out everything that I will need and how much it would cost. I have done research on bolt on mods like the plenum spacer, MREV2, exhaust, and bolt ons don't really seem worth it because your spending thousands just for maybe 10-30 more HP. Currently I have a stillen CAI on my G35 and I'm planning on making a grounding kit as well. It seems FI or Nitrous is the best bang for your buck on G35's. To safely run a 75 shot, what will I need, and how much would an engine rebuild or transmission rebuild cost on average worst case scenario if something goes wrong? And also how much does a dyno tune cost on average too?

 

It cost me around $790 with kit and installation, im only running a 50 shot and ive only had it for a week

 

I have a 05 sedan and I'm running 100shot. Definitely recommend 1 step colder plugs. I have DC intake and motordyne 5/16 plenum spacer and colder plugs.
