This 1997 Porsche 993 Cup 3.8 RSR is a direct descendant of race car royalty. In the early 1970s, the formidable Porsche 917 became a victim of its own success, as rule changes designed to end its dominance effectively regulated it out of racing. In something of a time crunch to develop a new prototype for the World Sportscar Championship, Porsche decided to go a different route and return to its tried-and-true 911.
Beginning with the 1973 911 RS, Porsche designed an all-out racer that incorporated every possible modification, right up to the ragged edge of the rules. It featured a high-revving 2.8-liter flat six, modified five-speed transaxle, limited-slip differential, brakes derived from the 917, uprated suspension, centrally located oil cooler, and massive fender flares housing enormous wheels and tires, and the now-iconic ducktail rear spoiler. The Porsche RSR was born. It was the purpose-built Porsche race car by which all others would be judged. The 1973 RSR and its 1974 3.0-liter successor would go on to vanquish all competitors for years to come.
In 1993, Porsche unveiled a new RSR based on the 964. It was a lightweight, wide-bodied, track-only terror, powered by a 3.8-liter flat six, conservatively rated at 320 hp. It was incredibly successful, logging class victories at Le Mans, Spa, Suzuka, Daytona, and others.
The Porsche 993 was the last of the revered air-cooled Porsche 911s, as fuel economy and emissions standards had effectively mandated a water-cooled successor. It was also the last truly hand-built 911, and Porsche engineers labored to ensure the final evolution would be the best and most advanced air-cooled car they could produce. Inspired by the outstanding 993 Carrera Cup and GT2 variants, Porsche developed a new RSR to race predominantly in the US and Japan, where class rules allowed it to compete. A true factory-built race car, the 993 Cup 3.8 RSR is a powerful, lightweight, track weapon.
This RSR, chassis 398063, is one of just 45 produced between 1996 and 1998. According to fascinating correspondence included with the sale, the car was ordered new in July 1996 by Michael Doolin of Sandy, Utah. In addition to its special race-prepared M64/75 3.8-liter engine and six-speed Cup transaxle, it was delivered in January 1997 equipped with massive 322 mm front and 299 mm rear-disc brakes, adjustable front and rear suspension, full welded roll cage, air jacks, integrated fire-suppression system, Recaro racing seat, Sabelt racing harness, lightweight glass, and 92-liter fuel cell.
The RSR’s menacing appearance is immediately recognizable with its imposing wheel flares, Turnwald front spoiler and rear wing, 18″ center-lock BBS gold-center magnesium wheels, tow hooks, and bonnet pins. This car stands apart even in the rarefied air of 993 RSRs, being one of a scant few to have departed the factory finished in iconic Guards Red.
Unlike the majority of RSRs, this car was never raced professionally. Rather, it enjoyed a pampered life of Porsche Club and National Auto Sport Association racing and was always treated with meticulous care. The original hood, doors, and rear wing were removed before racing the car to preserve their original finish and weren’t reinstalled until purchase by the consignor in June 2016. The car was subsequently sent to Kelly-Moss Racing in Wisconsin, where it received an engine-out inspection and service – with detailing and refurbishment where necessary – to return it to factory-fresh condition. The consignor believes the majority of its Guards Red finish remains original, a tribute to its lifetime of excellent care and careful use. Kelly-Moss refinished only the bumpers and fenders to remove painted-on graphics.
The opportunity to own the legendary RSR variant of the last, and arguably greatest, air-cooled 911 and its storied bloodline cannot be overstated. Having covered just over 8,000 careful miles from new, retaining its matching-numbers engine, and presented in exceedingly rare Guards Red, this moment in time may never be repeated. Offered with service invoices, correspondence from Porsche, technical information and parts manuals, racing logs, and air jack wand, this immaculate 993 Cup 3.8 RSR deserves a place in any serious Porsche collection or to be unleashed on the road course of choice.
