When it comes to building the ultimate 997 Turbo, some enthusiasts dream big, and then some make those dreams come true. Enter the Turbo Cab, a no-compromise street build that combines cutting-edge technology, aggressive performance upgrades, and a true passion for Porsche engineering. This isn’t just any 997 Turbo S; it’s the ultimate expression of power, precision, and purpose.

Let’s take a deep dive into what makes this 997 Turbo Cabriolet one of the most exciting builds on the streets.

Front Chassis: Precision and Performance

Every great build starts with a strong foundation, and the front chassis of this Turbo Cabriolet is engineered for nothing less than performance perfection.

• GT3 Front Uprights: To ensure optimal handling and response, the build utilizes GT3 front uprights, designed to handle the most aggressive track conditions while still offering street comfort.

• Custom-Bodied JRZ Dampers: These custom dampers are engineered to fit the front axles while maintaining the car’s AWD configuration, ensuring that both performance and driveability are top-notch.

• KW Suspension Front Axle Lift: For added versatility and practicality, the KW lift system allows the front end of the car to be raised when needed—perfect for navigating steep driveways or obstacles without sacrificing stance.

• Eisenlohr Racing Products Billet GT3 Control Arms: With billet GT3 control arms, bump steer arms, and tension rods, the suspension is dialed in for precision, ensuring no compromises in steering and handling.

• OEM GT3 Anti-Roll Bar & Tarett Engineering Drop Links: The combination of a GT3 anti-roll bar and drop links from Tarett Engineering allows for a more stable, controlled driving experience, minimizing body roll under heavy cornering.

Rear Chassis: Built for Speed and Stability

The rear chassis is equally aggressive, designed for ultimate performance on both the street and the track.

• 997 GT3 RS4.0L Uprights & Subframes: Upgrading to GT3 RS4.0L uprights and subframes ensures that this Turbo Cabriolet not only boasts exceptional strength but also precise handling characteristics.

• Billet GT3 Arms: Billet components provide an unbeatable combination of strength and weight savings, improving the overall response and feel of the car.

• Adjustable Rear Dog Bones & Tension Rods: These adjustments allow for fine-tuning of rear geometry, ensuring maximum grip and stability at any speed.

• OEM GT3 Anti-Roll Bar: Keeping the rear end firmly planted, the OEM GT3 ARB allows for better control through tight corners and high-speed sweepers.

• Fully Bump Steered, Corner Balanced, and Aligned: Every component of this rear chassis has been carefully tuned and balanced to perfection, ensuring that every bit of power can be transferred to the road with no loss in stability.

Engine: 1100 WHP of Pure, Unrelenting Power

If the chassis is where the car is held together, the engine is where the magic happens. This 997 Turbo Cabriolet is powered by a stage 2 Hillclimb engine built by the experts at BBI Autosport.

• CNC Ported Heads: The cylinder heads are ported using state-of-the-art CNC technology, improving airflow and combustion efficiency for serious performance gains.

• 3D-Printed 12-Injector Intake Manifold: A world-first in performance car engineering, this 12-injector intake manifold is 3D printed for ultimate precision and power delivery, helping to maintain consistent fueling even at extreme boost levels.

• Specialty Precision Welding Exhaust Manifolds: These prototype exhaust manifolds, crafted using 3D printing and turbo relocation by 6 inches, optimize turbo response and exhaust flow.

• V-Band Xona Rotor External Gated Turbos: Custom external gated turbos from Xona Rotor ensure maximum flow and precision boost control, while the Tial Sport wastegates and diverter valves manage exhaust pressure to perfection.

• AMS Performance Intercooler: To keep things cool under pressure, the AMS intercooler ensures that intake temps stay in check, while the custom Y-pipe and Verus Engineering hydro clamps ensure maximum flow with minimal restriction.

• Output: This monster engine is pushing 1100 WHP and a staggering 990 lb-ft of torque at 30 psi, making it one of the most powerful street-friendly builds around.

Gearbox: Precision Shifting

This build wouldn’t be complete without a transmission that can handle all that power. The PDK gearbox has been fully built in-house, with custom titanium hardware replacing the stock aluminum components for maximum durability. With Dodson Motorsport clutches and a billet oil pan kit, this gearbox is ready to handle the power required for such a machine.

Body: Aerodynamics Meets Aggression

The exterior of this Turbo Cabriolet has been transformed to match the performance beneath. Featuring GT3 Cup front and rear bumpers, this car means business.

• Modified PWR Radiators: To accommodate the new condenser mount, the radiators have been carefully modified, ensuring that cooling remains optimal even under extreme performance conditions.

• Custom Intercooler Ducting: The rear bumper has been custom-designed with intercooler ducting to ensure that the air-to-water intercoolers perform at their best—vital for sustaining power under the hood.
