2008-2009 Pontiac G8 (GT/GXP) Parts

The G8 GT and G8 GXP sedans were a set of wolves in sheep's clothing. Both naturally aspirated the G8 GT sported a 6.0L LS2 based motor putting down 361 horsepower and 384 ft-lbs of torque. The G8 GXP got upgraded to the aluminum LS3 (and got a very slick manual transmission option) helping it put down 415 horsepower and 415 ft-lbs of torque. These 2 naturally aspirated sedans were just asking for a blower and other sedan-enhancing mods and given that they live in the LSX family there are many power-adding options available for the G8 platform.
