The RUF BTR-Specification 1989 Porsche 911 Turbo Coupe represents an incredible chapter in automotive history. Starting as a factory 911 Turbo, this coupe was sent to RUF Automobile GmbH in Germany for their highly sought-after BTR conversion. The BTR, short for Gruppe B Turbo RUF, was one of the first standalone models to carry a RUF VIN. This specific example remained in Europe and was regularly serviced by RUF through 2016 before its importation to the US.
The Origins of RUF’s BTR Legend
The legacy of the BTR conversion started well before this 1989 Porsche 911 Turbo Coupe was built. RUF began modifying the Porsche 930 in 1977, but their manufacturing status came in 1981. They officially introduced the BTR in 1983, establishing themselves as a distinct automaker. Aside from building cars from scratch, RUF also offered to convert customer-supplied Porsches to various BTR specifications.
A Deep Dive into the Exterior Refresh
This BTR-Specification 1989 Porsche 911 Turbo recently benefited from a complete cosmetic refresh. Notably, the car was stripped to bare metal and refinished in its striking Black Metallic paint. During this thorough process, the body and glass seals were replaced, ensuring a tight and fresh presentation. New window moldings, stone guards, and various other trim pieces were also installed for a clean finish.
Signature RUF Bodywork and Wheels
The car’s appearance is enhanced by unmistakable RUF features. RUF front and rear valances give the vehicle a more aggressive, track-ready stance. The exterior also features amber front fog lights and the classic “tea tray” rear spoiler. Drilled door handles add a touch of detail while the car rides on staggered-width 17-inch RUF Speedline wheels. These wheels are currently wrapped in Michelin Pilot Sport PS2 tires.
Interior Appointments and RUF Details
Inside, the cabin is trimmed in attractive black leather with contrasting pale gray piping. The heated front sport seats feature power height adjustments for driver comfort. Matching black upholstery covers the dashboard, door panels, and fold-down rear seats. The color-matched carpeting includes RUF-branded floor mats, adding a custom touch.
Instrumentation and Driver Controls
The driver interacts with a RUF three-spoke steering wheel, a purposeful aesthetic choice. Behind it sits RUF-branded VDO instrumentation, essential for monitoring performance. The gauges include a central 8k-rpm tachometer and a 300-km/h speedometer. Other gauges track oil pressure, oil temperature, boost, and fuel/oil levels. A manual boost controller is neatly installed in front of the rear seats.
Unpacking the Heart of the BTR Conversion
The power plant is a turbocharged 3.4-liter Type 930 flat-six, a massive step up from the factory 3.3-liter engine. This displacement increase was achieved through a wider bore and the use of RUF-specific pistons and cylinder heads. Furthermore, a larger turbocharger and a RUF intercooler were installed to maximize performance. This combination results in a significant increase in both horsepower and torque.
Recent Engine and Drivetrain Rebuild
Between 2024 and 2025, the engine underwent an extensive and meticulous rebuild. This work included the machining of the cylinder heads for optimal seating and sealing. Key internal components were replaced, including the crankshaft, pistons, connecting rods, and all associated bearings. The timing chain, guides, and tensioners were also refreshed at this time. Power is routed through a G50/50 five-speed manual transaxle to the rear wheels. The clutch, its bearings, and hydraulic cylinders were replaced during the mechanical refresh.
Performance, Handling, and Underbody Care
The vehicle’s power and performance are complemented by its excellent handling setup. RUF installed Bilstein shocks to improve the car’s responsiveness and road holding characteristics. A strut brace is also fitted in the front compartment for added chassis rigidity. The stopping power comes from cross-drilled and ventilated disc brakes featuring striking red-painted calipers. The underside of the car was meticulously cleaned using a dry ice process during the recent service. This careful cleaning helps preserve the car’s condition.
This RUF BTR-Specification 1989 Porsche 911 Turbo Coupe offers staggering performance thanks to its mechanical upgrades. The rebuilt turbocharged 3.4-liter flat-six engine delivers substantial power to the rear wheels. The power delivery is controlled and precise thanks to the G50/50 five-speed manual transaxle and limited-slip differential. This combination provides an engaging and visceral driving experience. The car’s performance is a true testament to the engineering prowess of RUF Automobile GmbH.
Summary of a Legendary RUF Icon
Ultimately, this RUF BTR-Specification 1989 Porsche 911 Turbo Coupe is a meticulously maintained piece of automotive history. It showcases the best of RUF’s engineering talent applied to the classic 930 chassis. From its comprehensive engine rebuild to the gorgeous Black Metallic repaint and signature RUF components, this car is a definitive example of the BTR specification. It represents a potent, driver-focused machine that continues to impress decades after its conversion.
