1997 Porsche 993 Cup RSR Coupe

The Type 993 was introduced by Porsche in 1993, and was the last air-cooled 911 produced by the Germany Company. The stripped down race cars were officially named the 911 Cup 3.8 RSR and were developed to participate in national championship series in Europe, Japan, and the United States. Customers could select between three factory-built 3.8-liter engines, each one tuned to a different specification.

The majority of Porsche RSRs were used for professional competition; this example, however, was used in Porsche Club and National Auto Sport Association racing. 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 current owner in June 2016. It is believed that the majority of Guards Red finish is original. It has covered just over 8,000 miles from new, and retains its matching-numbers M64/75 engine.

This tuned engine is fitted with a resonance intake system, six intake plenums with separate throttle valves, a different camshaft profile, and no catalytic converters. The engine is equipped with the type M50/34 close-ratio six-speed manual transaxle.

This RSR was originally delivered to Michael Doolin of Sandy, Utah, in July 1997. Most of the 45 examples built to 3.8 RSR specification were raced extensively. However, this example was never race professionally, instead competing in Porsche Club races and National Auto Sport Association races.
