I have an 2007 g35s sedan. i was think about adding some nitrous. i see where people have added 75hp shot. my car is completely stock. nitrous is the only way i see right now to add 75hp quickly. but the nitrous kits i see available are adjustable pass 75hp. my question is wht will it take to shoot more than 75hp on my car. i am willing to get colder plugs and run high octane fuels. i see where some kits reccomend taking out 2 degrees of timing


my question is whats the most anyone has sprayed a stock 07 g35 and what problems did they see

is it really safe to go over 75hp

what options are there for turning down timing without going to a dyno shop

any and all advice and opinions are appreciated

 

....ur trying to run spray on a stock car with no tune?....goodluck bro.

 

I used to have a 75hp shot on my old 88 honda prelude, and it worked well. My motor never blew, but eventually my car would bog down instead of speed up after about 15k. I ended up getting another used under 60k motor and doing a swap, but I never knew what the issue was (engine had 90k on it lol). I did have a professional install it, it was a throttle body injection method, the simplest. That method the 'tuning' was simply to swap out different sized fuel and nos nozzles to see what worked best. With all the computer diags these days and a dyno tuning would be much easier and accurate. But if a 135 hp 2.3L 4cl can handle a 75hp shot, I'd imaging a nissan motor could. I wouldn't push it though on stock internals - like a turbo on stock motor, some people get boost happy after 8lbs and blow their motors

I do know the direct injection of nos works way better, but way more expensive to install - that way you get an consistent amount of the juice in all of your cylinders. I have no idea how what would work with the on the VQ motor, the way the intake plenum is designed.
