The 2008 Pontiac G8 GT arrived as a bold statement during the final years of the brand. Based on the Australian Holden Commodore, it brought rear-wheel-drive muscle back to the American sedan market. This specific example takes that performance foundation to an entirely different level. Reportedly displayed at the 2008 SEMA show, the car features a vibrant House of Kolors orange finish. It successfully blends early-2000s show car aesthetics with modern, forced-induction power. With only 22k miles, it remains a well-preserved piece of high-performance tuning history from a storied era.
Supercharged V8 Performance Upgrades
At the heart of this 2008 Pontiac G8 GT lies a 6.0-liter V8 engine. While the stock power was impressive, a ProCharger P-1SC-1 supercharger now provides significant boost. The engine also features an XP Racing Monster camshaft and a displacement-on-demand delete kit. These modifications required revised ECU tuning and an uprated fuel system to maintain reliability. Consequently, a dynamometer report shows a peak output of 534 horsepower at the rear wheels. The engine bay even features color-matched components to mirror the striking exterior paint.
Chassis and Braking Enhancements
Handling all that supercharged power requires more than just a stock suspension. This 2008 Pontiac G8 GT rides on a full Pedders suspension setup for improved cornering. To ensure the car stops as fast as it accelerates, engineers fitted Baer six-piston calipers. These brakes work in tandem with multi-piece rotors visible behind 20-inch OZ Racing wheels. A Pedders strut tower brace spans the engine bay to further stiffen the chassis during hard cornering. These upgrades transform the sedan into a machine capable of handling both track days and daily commutes.
Custom Interior and Entertainment
The cabin of this 2008 Pontiac G8 GT received as much attention as the mechanicals. Roadwire black and gray leather covers provide a premium feel to the heated front seats. Rear-seat passengers can enjoy Eclipse entertainment screens mounted directly into the headrests. For audio enthusiasts, the trunk houses a dedicated amplifier and subwoofer system. A Blaupunkt 11-speaker sound system ensures high-fidelity playback throughout the entire interior. These appointments make the car an excellent choice for long-distance touring or showing at local events.
Mechanical Specs and Power Delivery
The drivetrain of this 2008 Pontiac G8 GT is built for high-performance durability. Its 6.0-liter V8 produces 534 horsepower and 437 lb-ft of torque under boost. A six-speed automatic transmission manages the power, sending it directly to a limited-slip differential. The exterior features extended rocker panels and a ducktail rear spoiler to improve aerodynamic stability. Furthermore, the multi-piece OZ Racing wheels provide a lightweight solution to reduce unsprung weight. This combination of parts ensures the car remains a formidable competitor on the street.
Summary of the G8 GT Build
This 2008 Pontiac G8 GT represents a unique opportunity to own a verified show car. It balances a decade of performance heritage with a suite of high-end mechanical upgrades. While the Illinois title carries a rebuilt brand, the car’s presence and power are undeniable. It serves as a reminder of Pontiac’s dedication to the rear-wheel-drive performance sedan. Whether on a display stand or an open highway, this orange G8 GT makes a loud statement. It remains a true enthusiast’s car with the hardware to back up its aggressive looks.
