For the 2001 model year, Porsche introduced the all-wheel-drive Turbo variant with face-lifted bodywork with larger ducts at the front bumper to improve airflow to the radiators before the front wheels, widened fenders with large intake ducts before the rear wheel arches, and distinctive vents for the intercoolers at the rear bumper. The body shell was completely redesigned, with smoother lines and a raked-back windshield that made the cabin significantly roomier. Additionally, the chassis was 45% stiffer than the older model, yet it managed to be lighter than the older models.
The Turbo S models introduced in 2005 made the X50 package standard, bringing the horsepower rating from 420 to 450 with larger turbos, intercoolers, an ECU tune, reinforced gearbox, and Ceramic Composite brakes (PCCB). Since the M96 engine’s lineage can be traced back to the 996 GT3 and the 600-horsepower GT1 race car, it has been proven to be a durable power plant that was able to withstand tuning to reliably extract tremendous horsepower figures.
Knowing exactly what the possibilities of the Turbo’s engine were, the owner of this 911 began building his vision of the ideal street-legal supercar. Beginning with a well-optioned Arctic Silver Metallic over Boxster Red leather 2005 Turbo S, the owner enlisted the help of some highly respected names in the Porsche industry to make his vision a reality.
A no-expense-spared approach was taken to build a fully drivable and reliable car that would produce over 600 horsepower while still remaining within the safe limits of the engine’s OEM internals. In total, over $40,000 in parts alone were spent in improving the engine and chassis dynamics. Horsepower at the crank from the engine modifications is estimated at 660 horsepower/530 lb-ft of torque on 93 octane fuel and 680 horsepower/598 lb-ft of torque on 100 octane fuel.
While this 996 Turbo was built with maximum performance in mind, it has never been raced on a track or drag raced, instead has been driven extensively on road trips. A copy of the Porsche Certificate of Authenticity that has been signed by Jerry Seinfeld is included with the car, along with a list of the extensive modifications performed and the associated invoices outlining the labor performed.
