Built for the rigors of European Pro GT racing and the North American Supercar Series, Porsche’s Type 964-based Carrera RSR 3.8 of 1993 and 1994 represented the marque’s uncompromising return to production-based motorsport dominance. At its core was the formidable, naturally aspirated 3.8-liter air-cooled flat-six Type M64/04 engine. Though officially rated at 325 horsepower, real-world output is believed to have ranged from 375 to 390 horsepower. Derived from the standard 3.6-liter unit, the engine featured increased compression, dual ignition, individual throttle butterflies, Bosch electronic fuel injection, and dry-sump lubrication. Power was delivered through a racing clutch to a five-speed manual transaxle with limited-slip differential.

Bodied on the standard 964 production line, each RSR shell was seam-welded for strength before being sent to Matter for the installation of a fully triangulated roll cage. Additional features included light-alloy doors and front lids, a steel engine cover to support the large fiberglass rear wing, lightweight front and rear bumper facias, thinner side and rear windows, and a large front-mounted oil cooler. Suspension was fully uprated with stainless-steel Heim joints, competition Bilstein dampers, and Turbo S-derived brakes housed inside 18-inch center-lock Speedline modular wheels. Tipping the scales at just 2,673 pounds dry, the RSR 3.8 was not only under the FIA minimum weight limit, it was blisteringly fast: capable of 0-60 mph in 3.7 seconds, its top speed exceeded 180 mph.

The Carrera RSR 3.8 offered here, chassis 496096, stands among the most compellingly specified examples, purpose-built for endurance competition and subsequently the subject of a careful restoration by leading marque specialists. As documented by copies of its original sales invoice and order form on file, chassis 496096 was completed in December 1993, finished in Grand Prix White (L908) with a black single racing seat, and equipped with a 120-liter fuel tank, unassisted steering, air jacks, center-lock 18-inch RS 3.8 wheels, double fuel-filler, Le Mans exhaust, and a reserve fuel pump.

One of three Carrera RSR 3.8s originally commissioned by US-based Morse Motorsport, who ultimately did not take delivery, chassis 496096 was instead allocated to Japan, where it was acquired by Nova Engineering of Shizuoka-Ken. Nova Engineering is believed to have campaigned the RSR as intended, entering it in several rounds of the All-Japan GT Championship. In 1995, the car was reportedly sold to Team Kunimitsu, who continued to campaign it during that season’s All-Japan GT Championship series.

Following its acquisition by new ownership in 2007, chassis 496096 made a return to its native Germany, where it underwent an extensive refresh by the renowned Freisinger Motorsport of Karlsruhe. Since then, the car has enjoyed a well-deserved retirement, spending the better part of the last two decades on display within a prominent private collection. In May 2025, it received a service by Roock Sportsystem of Leverkusen, which included a thorough overhaul of the fuel system, featuring a bladder cleaning, fresh foam, and new in-tank pumps, as well as a cleaning of the fuel injectors and exhaust system. The car is offered with a Roock Sportsystem service invoice and report verifying the presence of its matching-numbers engine as well as a Deutscher Motor Sport Bund car passport granting eligibility for a range of historic racing events.

With its limited production, motorsport pedigree, and formidable performance, this Carrera RSR 3.8 offers a rare opportunity to acquire a factory-built, air-cooled racing 911, equally suited for concours display or a return to spirited competitive use.
