This TECHART GTstreet R America (No. 4 of 10) based on a 2021 Porsche 911 Turbo S Coupe is a meticulously executed, multi-stage build that elevates an already formidable 992 platform into something far more exclusive and purpose-driven. Starting from a ~$230,000 base and now showing just over 16,000 miles, this all-wheel-drive 641-horsepower Turbo S has been transformed into an ultra-rare, collectible limited-production model, with over $475,000 invested into its development. The foundation begins with the full TECHART GTstreet R America package, introducing a comprehensive aerodynamic redesign, carbon-intensive bodywork, factory performance enhancements, and official serial designation. From there, the build evolved into a far more extensive vision, incorporating significant performance upgrades, a fully bespoke interior finished in black leather with Guards Red stitching and houndstooth inserts, and meticulous refinement to ensure seamless integration throughout. Internally referred to as “Lady Sansa,” this example stands apart from both a standard Turbo S and even a typical GTstreet R, representing a one-of-one level execution that is visually striking, mechanically enhanced, and fully supported by documentation. As one of just ten GTstreet R America units, it offers a rare opportunity to own a highly individualized interpretation of TECHART’s flagship program.
The exterior of this TECHART GTstreet R America based on a 2021 Porsche 911 Turbo S Coupe is a masterclass in aggressive yet cohesive design. The full GTstreet R aerodynamic package transforms the already muscular 992 into something far more exotic, featuring a carbon-intensive composition that includes a sculpted front apron, vented aero hood, widened fenders, deep side skirts, and a dramatic multi-element rear wing. Every component is purpose-built, contributing both to visual presence and aerodynamic performance. The car is finished in a full Guards Red wrap, a bold and unmistakable choice that amplifies its commanding presence, while the underlying bodywork benefits from extensive fitment, paintwork, and refinement to achieve a factory-quality result. TECHART Formula VI Race wheels paired with Michelin Pilot Sport Cup 2 tires complete the stance, further enhanced by H&R lowering springs. The interior of this TECHART GTstreet R America based on a 2021 Porsche 911 Turbo S Coupe is where craftsmanship truly meets individuality. Completely reupholstered, the cabin features black leather throughout, accented by Guards Red stitching and striking red/black houndstooth inserts across the seats, door panels, and dashboard. This bespoke execution elevates the interior well beyond factory or even standard TECHART specifications. Complementing this is the TECHART steering wheel in leather and Alcantara, along with illuminated carbon door sills, aluminum pedals, and GTstreet R-specific elements including the serial designation and accessories. Additional refinements include a red gauge cluster and clock dial conversion, as well as a digital rearview mirror for modern usability. The result is an interior that feels both tailored and performance-focused, blending classic motorsport cues with contemporary luxury.
Powering this build is a heavily upgraded 3.8L twin-turbocharged flat-six that has been pushed deep into hypercar territory through a carefully staged performance program. Originally based on the Turbo S platform, the car was extensively enhanced with upgraded turbochargers, intercoolers, intake components, and a full performance exhaust system, alongside custom ECU and transmission calibration. The final configuration features a Pure1000 turbo setup paired with a refined Stage 3 calibration tailored to its catless system, resulting in an astonishing output of approximately 1,050+ horsepower and 1,060 lb-ft of torque. Power is delivered through Porsche’s 8-speed PDK transmission and all-wheel-drive system, creating a brutally fast yet highly composed driving experience that retains the usability, balance, and engineering integrity that define the 911 Turbo S platform.
For many Porsche purists, the 997-generation 911 represents the sweet spot between modern usability and classic analog engagement.

The result is a beautifully spec’d modern 911 that combines luxury, everyday drivability, and serious sports car capability in one unmistakably Porsche package.
The Porsche 911 SC is widely regarded as one of the most important models in the history of the 911 lineage.
