1984 Porsche 911SC

This 1984 Porsche 911 SC/RS is the last of 20 lightweight rally specials produced to meet Group B homologation requirements for the 1984 World Rally Championship season. Chassis 021 was delivered new to Van Dijk Racing in Switzerland on March 6, 1984, and made its lone racing appearance with a 14th-place finish in the 1984 Tour de Corse in France. The car was purchased from Tycho Van Dijk in 2004 by its current owner, who subsequently brought it to the US. Finished in white with Rothmans decals, it is powered by a 3.0-liter Type 930/18 flat-six that features a 10.3:1 compression ratio, dry-sump lubrication, and Bosch-Kugelfischer mechanical fuel injection. Additional features include a Type 915/71 five-speed manual transaxle with an integrated oil cooler and a limited-slip differential, an engine oil cooler, 917-derived cross-drilled and ventilated disc brakes, adjustable Bilstein dampers with coilover helper springs, body-color staggered-width 16” Fuchs alloy wheels, an 80-liter fuel tank, quad hood-mounted rally lights, an aluminum skid plate, a roll cage with removable door bars, racing seats upholstered in black, a fuel-operated heater, and a Jaegar rally calculator. This Type 954 now shows 5k kilometers (~3k miles) and is offered on dealer consignment in California with an inspection report from Jürgen Barth, a Porsche Classic Technical Certificate, a copy of its factory data card, its previous Swiss registration document, a technical manual, 1984 Tour de Corse route books, and a Montana title. The SC/RS variant was developed under the leadership of Jürgen Barth as a means to provide sponsor Rothmans with a 911-based rally candidate that could be homologated for Group B as an evolution of the 911SC. While five of the 20 examples built were retained for Rothmans team use, the remaining 15 were sold to customers in either street or race configuration Construction of the SC/RS was based on the 930 platform and featured a lightweight body shell, aluminum opening panels, fiberglass front and rear bumpers, and thin-gauge glass. This example is finished in white, and Rothmans Rallye de France decals were applied to each door in February 2024, at which time red side-stripe decals were removed. Features include a whale-tail rear spoiler, a front chin spoiler beneath a front valance with dual air ducts, quad hood-mounted rally lights under a body-color cover, a driver-side mirror, and a roof-mounted antenna. Fuchs alloy wheels measuring 16×7” up front and 16×8” at the rear were refinished with a color change from red to white in preparation for the sale, at which time Michelin Pilot Sport All-Season tires measuring 205/55 and 225/50 were mounted. Stopping is handled by cross-drilled and ventilated disc brakes with four-piston calipers all around and dual master cylinders with adjustable bias. The cockpit houses a pair of racing seats upholstered in black cloth and equipped with Sabelt four-point harnesses. The SC/RS interior is absent of rear seats, door pockets, a glovebox door, or a clock and features a Matter roll cage with removable door bars, black carpeting of thinner depth than the standard 911, roll-up windows, a Realistic CB radio, and a Jaeger rally computer. An Eberspacher fuel-operated heater is situated in the front compartment underneath an aluminum cover. The three-spoke steering wheel sits ahead of VDO instrumentation including a central 10k-rpm tachometer, a 300-km/h speedometer, and gauges monitoring fuel level, oil level, oil pressure, and oil temperature. The six-digit odometer shows 5k kilometers (~3k miles). The 3.0-liter flat-six was based on the 911SC’s powerplant and featured a 10.3:1 compression ratio, Type 935 cylinder heads, competition camshafts with increased valve lift, Bosch-Kugelfischer fuel injection with a plunger-style pump, and dry-sump lubrication with a front-mounted oil cooler. Output for race-specification examples was factory rated at 270 horsepower. Fluid changes were performed in preparation for the sale, and the fuel was drained and refilled. Power is sent to the rear wheels via a Type 915/71 five-speed manual transaxle with a designated fluid cooler, a limited-slip differential with 40% lockup, and an RSR-style clutch. Torsion-bar suspension incorporates adjustable pickup points as well as Bilstein adjustable dampers with coilover helper springs. An aluminum skid plate is fitted to the underbody. Engine number 63E09016 is shown stamped on the case, and a stamp of engine type number 930/18 can be seen in the photo gallery below. An inspection report provided by Jürgen Barth in 2017 discusses the history and details of the car. Additional pages of the report can be viewed in the gallery, as can a copy of the car’s factory data card and a test report on the car published in a 1984 issue of Echappement magazine. The car underwent a Porsche Classic technical inspection in March 2024, and the resulting certificate is included in the gallery. The car has not passed a California emissions test.
