This 1992 Porsche 911 is one of 45 Carrera Cup models sent to the US to be converted by Andial for a planned single-make racing series. Porsche terminated the series before it began and instead had the cars prepared for street use and distributed to dealers for public sale. This example was originally purchased at Olmstead Motor Cars in Charleston, South Carolina, and later moved to Florida. It was sold to the previous owner in 2005 and brought to New Jersey, where it was acquired for the seller’s collection in early 2014. Finished in Grand Prix White, the car retains its numbers-matching 3.6-liter M64 flat-six and five-speed G50 transaxle. Additional factory features include a limited-slip differential, aluminum hood, chassis reinforcement, adjustable stabilizer bars, Turbo-style brakes, manual steering, and several weight-saving measures. The car’s interior has been converted to an Andial-style racing setup with a welded-in roll cage, Recaro racing seats, and Schroth harnesses. Now showing 58k miles, this 964 is offered in New Jersey with a copy of its original window sticker, a dashboard plaque, a Porsche Certificate of Authenticity, owner’s manuals, service records, a clean Carfax report, and a clean Montana title in the name seller’s LLC.
Inspired by the success of Carrera Cup programs in Germany, the US Cup series was canceled less than a month before its first scheduled race, with Porsche citing an inability to find a title sponsor. The would-be race cars began life as special variants of the European Carrera RS and were adjusted by Porsche to meet US regulations before being modified for racing by Andial in California. Only 25 of the cars were converted by Andial before they were reverted to street specification and sold along with the 20 unconverted cars as Carrera Cup Editions.
Features distinguishing Cup cars from other US models include rolled fenders, an aluminum front hood without gas struts, special non-electric side mirrors, chassis reinforcement welds, and omission of various rust-proofing materials. This example is finished in Grand Prix White, as were all but one of the US Cup cars, and Carrera Cup roundels with the number 29 have been added to the doors and front hood. The seller believes that portions of the car was repainted prior to his ownership, and the rear bumper was refinished in October 2020 due to yellowing.
Cup wheels measuring 17×8” and 17×9.5” were acquired by the seller in 2017 and match the dimensional specifications intended for Andial-prepared cars. After being mounted with Michelin Pilot Sport tires, sized 225/45 and 255/40, the wheels were installed on the car in October 2020 with 21mm rear spacers and 65mm rear studs. The braking system incorporates ABS and Turbo-style calipers, in addition to ventilated and cross-drilled rotors measuring 322mm in diameter up front and 299mm out back. The system was flushed in October 2020, and various fittings were also replaced.
The interior was modified during previous ownership to recreate elements of the Andial racing setup, including Recaro seats marked with the Porsche crest. Schroth six-point harnesses are in place for each occupant. A roll cage has been welded in and is said to replicate a European Cup car cage with additional door bars. The carpeting has been removed and replaced with Cup-style, spray-painted plywood floor coverings. Door panels with pull straps have been retained.
A MOMO steering wheels frames VDO instrumentation, including a 7,600-rpm tachometer, 180-mph speedometer, and clock, in addition to gauges that monitor fuel level, oil level, oil temperature, and oil pressure. The six-digit odometer shows approximately 58k miles, 2k of which have been added by the seller. Carrera Cup USA models were delivered without air conditioning, rear seats, sound insulation, or a radio, but were equipped with dual airbags, power windows, door beams, and a third rear brake light. The driver’s window switch was replaced in October 2020.
US-market Carrera Cups were fitted with the blueprinted 3.6L flat-six used in the Carrera RS, which featured selectively matched pistons and cylinders. Factory-rated output was 256 horsepower and 240 lb-ft of torque. Additional features include sport-tuned Bosch DME engine management, solid rubber engine mounts, a sport flywheel in lieu of the standard Carrera’s dual-mass unit, a 36-ampere-hour battery, and an electrical kill switch. A cold-start can be viewed here.
Power is sent to the rear wheels through a close-ratio five-speed manual transaxle with steel synchronizers and a 20/100 percent variable-lock limited-slip differential. Cup USA cars also featured a short-throw shifter moved closer to the driver. Service performed in October 2020 included changing the oil and transaxle fluid, as well as replacing the battery, air filter, alternator fan shroud, and rear decklid strut.
Case stamping 62N81377 is shown above and matches the engine number listed on the Porsche CoA, which is pictured in the gallery below. Transaxle stamping 2002901 is pictured in the gallery and also matches the CoA.
The suspension of Carrera Cup USA cars is distinguished from other US variants by the following components:
- 24mm adjustable front stabilizer bar
- 18mm adjustable rear stabilizer bar
- Aluminum front hubs
- Harder rubber front lower control arm bushings
- Ball joint upper spring strut mounts
- Modified rear spring plates and trailing arm control mounts
- Firmer Bilstein shock absorbers
- Higher progressive rate springs
- Front ride height lower by 50mm
- Rear ride height lower by 45mm
A copy of the original window sticker lists the Carrera Cup Edition package, which added $13,740 to the total new price. Each car was also accompanied by a Carrera Cup USA dash plaque listing its VIN, and this car’s uninstalled plaque is shown in the gallery below. Also included in the gallery are 1992 Carrera Cup USA specification sheets from Porsche, letters responding to the original owner’s requests for racing sponsorship, service invoices from 2005 to present, and a collection of articles on the history and specifications of Carrera Cup cars.
