1979 Porsche 911 RSR 3.0 IROC Tribute for sale!

Location: Boulder, Colorado 80304

What We Like: Few are aware that the Porsche 911 RSR 3.0 helped launch the International Race Of Champions (IROC) series in 1974. This Porsche 911 RSR IROC tribute sparks memories of racers like Bobby Unser, Richard Petty, and especially Mark Donohue, who piloted an orange RSR IROC in the final race, securing the championship in the process. The resto-mod process was carried out by respected Porsche tuner Patrick Motorsports in 2020 and employs a 1979 911 Turbo as its base. A lightweight chassis paired with a 300-plus horsepower 3.8L flat-six ensures period-correct performance while computerized engine management provides reliability. With approximately 1,500 miles driven since the high-quality build was complete, this car provides an opportunity for anyone seeking to enjoy a 911 RSR IROC without the seven-figure price tag.

Vehicle History & Overview

This 1974 IROC tribute started life as a 1979 911 Turbo. Patrick Motorsports completed the conversion in late 2020. The 911 Turbo lent its factory wide bodywork, 917-derived brakes, and upgraded suspension. A fuel-injected, enlarged 3.8L flat-six pulled from a 993-chassis 911 was paired with a specially-prepared, Euro-spec 915-series 5-speed manual transmission, limited-slip-differential, and wide Fuchs alloys wrapped in period-correct Michelin TB15 tires. RSR-style front/rear bumpers and an RSR-style rear wing complete the package. Approximately 1,500 miles have been added since the owner took delivery December 2020. Per the selling dealer, the original Recaro seats will be included in the sale.

The 911 RSR was conceived and developed to compete in production-based endurance racing. Debuting in 1973, it accomplished its mission, enjoying substantial on-track success. Building on the well-established RSR legacy, Porsche created the 1974 911 RSR 3.0. Changes included an enlarged 3.0L flat-six, improved aerodynamics, and wider wheels. Identically-prepared 1974 RSRs formed the basis of the inaugural IROC series. In addition to its legendary IROC status, the 911 RSR 3.0 dominated GT-class racing, at times competing for overall victory against the prototype-class cars.
