View Photos of the 1984 Porsche 911 Ruf RSR

This Ruf RSR began life as a 911 Carrera 3.2 in the paint-to-sample color of Tornado Red from the Audi catalog.

In 1985, Alan Johnson Racing in San Diego crafted its roll cage and wild slant-nose Porsche 935-inspired body.

While it once featured a Ruf-tuned 3.4-liter flat-six, it now sports an air-cooled twin-turbo 3.8-liter flat-six from Protomotive in Harrison, Arkansas.

Sourced from a 993 911 Turbo and enlarged from 3.6 to 3.8 liters, the current engine makes a claimed 780 horsepower on race fuel.

This 911’s rear visibility is impaired, not only by the enormity of its rear spoiler but also by its roll cage.

This RSR’s original Ruf seats and steering wheel have been lost over the years. More modern replacements from Recaro and Momo have since been fitted.

The car’s original Ruf gauges remain, including a boost gauge, 8000-rpm tachometer, and a 210-mph speedometer.

While the car’s original 17-inch five-spoke Ruf alloy wheels are missing, its modern BBS replacements look awfully sharp.

This Ruf RSR is expected to fetch between $200,000 and $250,000 when it goes up for auction in early 2021.
