350Z newb here...Not new to cars, forced induction, etc though.
I'm potentially buying my buddies '03 G35. It currently has a Stillen Stage 3 supercharger on it with a SMALL custom pulley.(this is Boulder Nissan's kit they had on a 350Z a while back) Boost currently reads 9lbs throughout the entire powerband, it doesn't really waver at all. On 93 octane, there is no detonation except on hot days very slight detonation can be detected near redline in 3rd gear only.(only a handfull of WOT runs have been made since the kit was installed)
My question is: Is there ANY way to feasibly run 9psi on a stock bottom end? Such as the stage 5 kit, 2 step colder plugs, colder thermostat, anything??? The car will only be run on 93 octane at all times, I can get it cheap locally so thats not a problem.
Thanks for any and all info. and input you can share.
Thanks.

ttt...anyone have some info? I did a search and read all the Stillen supercharger posts but didn't get an answer to this "exact" question.
Thanks for any info.

I wouldnt run at 9psi if you have detonation . You need to have it tuned . I would call Stillen and see what they say and ask the same questions

 

Probably lower the timing and lose some power.

 

Better than blowing it up . One phone call could answer his questions
