Hey Guys,

How can I add horse power to my 2009 G37 Coupe without voiding the warranty.

I do not want to go over 400 hp. What changes do you recommend and how much hp and torque does each add?

Thanks,

Geoff Massa

 

sorry to be the bearer of bad news, but you won't get even close to 400 whp if you do all bolt ons and a tune. people have gotten 300+ whp with bolt ons i think. only way you'll get close to 400+ is f/i.

 

NOS! and use the search button...please can i be mod so i can delete these threads!!!

 

you can't.... mystery solved.
