Hello all. I am new to the forum as well as very new to grand prixs. I just purchased an 07 gt and am having trouble finding information about possible mods and upgrades. This is my first car, i am usually a jeep guy but am broadening my horizons. I am mostly interested in engine mods. I would really like to get into the 300hp range with the car with out having to be a master mechanic. Any info will be appreciated. Thank you
