duPont REGISTRY Live is proud to present this 1984 Porsche 911 Turbo RUF BTR, an early and highly significant example of RUF’s legendary turbocharged conversions, believed to be 1 of approximately 30 dealer-built cars produced prior to the introduction of RUF’s proprietary W09 VIN designation. Finished in Ruby Red Metallic (X7) over a burgundy leather interior, this example features a RUF-serialized 3.4-liter turbo flat-six and retains the distinctive character that defined RUF’s rise as one of the most respected Porsche tuners of the era.

At its core is a built, numbers matching 3.4-liter turbocharged flat-six, extensively upgraded with RUF Group B camshafts, Mahle racing pistons, Carillo connecting rods, and twin-plug ignition supported by Permatune CD ignition boxes. Induction is handled by a K-27 turbocharger with European-spec Bosch CIS injection and an ANDIAL fuel enrichment system, while a polished and ported intake and Borla exhaust further enhance performance. Cooling and reliability are addressed with a front-mounted oil cooler and ANDIAL intercooler. Power is delivered through a rare “dog-leg” 5-speed manual transmission, paired with a RUF lightweight pressure plate and street/sport clutch disc. Handling is supported by RUF sway bars, contributing to the car’s well-rounded performance capabilities.

Inside, the cabin is finished in burgundy leather upholstery and features a full color-matched roll cage, reinforcing the car’s performance-focused intent. A Fittipaldi racing steering wheel sits ahead of an ANDIAL-branded tachometer, reflecting the car’s period-correct tuning pedigree. Additional features include power windows, an electric sliding sunroof, air conditioning, and a cassette radio, blending classic 911 usability with motorsport-inspired details. The interior presents in well-kept condition, consistent with the car’s specialized nature.

The exterior is finished in Ruby Red Metallic (X7) and protected by full-body paint protection film. The car is fitted with slant-nose front bodywork with vented fenders and pop-up headlights, a defining visual feature of high-performance 911 conversions of the period. Additional details include a rear “whale tail” spoiler, shaved drip rails, a RUF lower front valence, and staggered 17-inch RUF wheels, all contributing to the car’s aggressive and unmistakable presence.

AutoCheck history on this car begins in 1996 and shows ownership in Wichita, Kansas until 2018 when it was registered in Miami, Florida. Accompanying the sale are two keys and the Porsche Production Specification sheet. As an early RUF dealer-built BTR with a serialized transmission, extensive period-correct performance upgrades, and distinctive slant-nose configuration, this 1984 Porsche 911 Turbo RUF BTR represents a rare opportunity to acquire a historically significant example from one of Porsche’s most revered tuning houses.
