The Porsche 993 RSR was developed by Porsche Motorsport for international GT competition. Introduced in 1997, it was based on the 993 Cup 3.8, but extensively re-engineered to support Porsche customer race team entries in international endurance events.
Powered by a 3.8-liter flat-six, the 993 RSR developed approximately 340 hp at 7,000 rpm and 280 lbs./ft. of torque. The engine utilized individual throttle bodies, dry sump lubrication, and strengthened internals for sustained high-rev performance. Optimized for circuit use, a close-ratio G50/34 six-speed manual transaxle delivered power to the rear wheels.
Bodywork featured wide GT2-style fender flares, lightweight panels, and a prominent rear wing. A stripped cockpit was outfitted with a welded roll cage, Recaro racing seat, and a fire suppression system. Chassis enhancements included adjustable suspension, reinforced control arms, and enlarged brakes with dedicated cooling ducts.
Weighing approximately 2,470 pounds, the 993 RSR proved highly competitive, achieving class wins at the 24 Hours of Daytona, 12 Hours of Sebring, and Spa 24 Hours.
This 1995 Porsche 993 Cup RSR began life as a Cup car, sourced directly from Porsche Motorsport North America (PMNA) by Georgia-based J3 Racing for competition in the Speedvision World Challenge. Due to the limited availability of factory-built RSRs, PMNA’s Alwin Springer offered J3 a 993 Cup along with the necessary components to convert it to full RSR specification.
The conversion included RSR-specification pistons, rods, heads, cams, slide valves, intake, engine management, and exhaust, adding an estimated 30 hp. RSR suspension components, upgraded brakes, sway bars, fuel cell, and pumps completed the transformation.
The RSR reportedly competed in two Speedvision World Challenge rounds and eight SCCA Southeast events in 1999, capturing the SCCA GT1 class championship. The following year, it ran the full 10-round Speedvision World Challenge GT series with J3 team owner Jaye Jackson’s son, Justin Jackson, said to have earned “Rookie of the Year” honors by round seven and finishing 5th Overall in a very competitive field.
The RSR saw limited use in Porsche Club of America and historic events through 2002, before being retired and displayed. It was later acquired by accomplished privateers Alan Benjamin and subsequently Alex Welch, both of whom campaigned the car in club and historic racing.
More recently purchased by a Porsche collector and amateur endurance driver with entries at Le Mans, Daytona, Sebring, and Spa, this 993 RSR is presented in a livery said to evoke the distinctive Alex Job Racing RSRs of the era. Built with support from PMNA and developed for top-level privateer competition, it combines authentic specification with period racing pedigree – an ideal candidate for historic events or a standout addition to any Porsche collection.
