Product Information

ABS was standard – and excellent for 1986 – but can be troublesome today. Beware if it feels like there’s no servo assistance (a heavy pedal) or the ABS warning lamp on the dashboard stays on after start-up. The cause could be dirty or broken wheel sensors, pump failure, broken wiring, fluid level sensors or blown fuses. Diagnostics is expensive, and most parts are pricey. The RS Cosworth gave the Sierra range proper ‘street cred’. Ford Motorsport under Stuart Turner needed a Group A saloon to replace the Capri. Conveniently, Cosworth had developed a 16-valve twin-cam version of the Pinto engine that, once turbocharged, would create a stonking Touring Car in the light three-door fleet Sierra bodyshell. The new two-way 'ultra' speed camera drivers must watch out for! Here's what they look like and how they work The price also suggests that both buyers considered this a one-off opportunity and indeed, it is unlikely to be repeated.”

Compare the chassis number on the logbook with the number on the VIN plate riveted to the slam panel and beneath a flap in the carpet beside the driver’s seat; it should read WF0EXXGBBE, followed by a series of two letters and five digits; these last seven characters should match the original engine number. Beware of missing stamps, although several Sierras have been welded over due to rotten inner sills. Any ground-off or home-stamped number is a special code that translates as ‘run away.’ The Sierra Cosworth was also pressed into service as a rally car, and saw some success. After the abolition of the Group B formula in the World Rally Championship at the end of 1986, manufacturers had to turn to Group A cars and Ford, like most others, found itself without a fully suitable car. The Cosworth was very powerful but, with only rear-wheel-drive, lost out to the four-wheel-drive Lancias and Mazdas on loose-surface events, while the four-wheel-drive XR4x4 had an excellent chassis but an elderly engine producing only around 230bhp, at least 80 less than the Lancia. For the 1987 season the team ran both, using the XR4x4 on loose surfaces and the Cosworth on tarmac, but the XR4x4's power disadvantage was too great and from 1988 the team concentrated on the Cosworth alone, and continued to use it until the arrival of the Sierra RS Cosworth 4x4 in 1990.March 1985– Sierra RS Cosworth unveiled at Geneva Motor Show. Assembly of at least ten pre-production cars takes place throughout the year. Motorsport homologation requires 5000 production cars for eligibility in Group A touring car racing. Misfires are common; the rotor arm, dizzy cap, leads and plugs must be 100% (or uprated to a wasted-spark system). Crank and cam sensor settings are also critical. Always compression-test a misfiring engine before buying, in case a holed piston or similar is to blame. Big money chases factory-original Cossies, so many masquerading as unmodified cars led previous lives as 500bhp hooligans. Launched for sale in July 1986 and based on the three-door Sierra body-shell, it was designed by Ford's Special Vehicle Engineering (SVE) and was powered by a Cosworth-designed 2.0-litre turbo engine of now-legendary repute. At the time, the Sierra Cosworth was a new kind of performance car - a 'blue-collar hero' able to humble true sports cars.

Speaking about the glasses, this is to me THE point that can make or break your model of a Ford Sierra. The rear window MUST NOT be sharped. It is NOT. It is rounded, subtly, with a break that ends rounded. That is exactly what I’ve highly suggested to Inno64 (and what they did), and I don’t think they needed me to warn about that because they know how to make a minicar, but I’ve seen others Ford Sierra tooled with very sharped rear windows (CM’s for example). Maybe an image such as below is more speaking : A number of other contenders were rejected before stumbling across 'E378 TKN' which they believed was - and still is - the best condition Cossie in the country.December 1982 –Sierra XR4i available, featuring 150bhp 2.8-litre Cologne V6 engine, sports styling with double rear spoiler and unusual three-door bodywork with split rear side windows. Around fourteen years ago, the vendor - described as 'a knowledgeable and particularly fastidious enthusiast' - had decided to add an RS500 to his collection and embarked on finding the best example there is. Misfires are a familiar factor of Cosworth ownership – sometimes serious (such as a blown head gasket) but usually symptomatic of an aged electrical or ignition system. Cossies are renowned for eating spark plugs, leads and coil, and many issues are cured with a wasted spark conversion – but that detracts from originality and value. Boost problems may be due to split or loose hoses, sensors and regulators. Swapping paper gaskets for Cometic type is useful (especially at the inlet manifold), while a replacement engine loom can work wonders.

Therefore, an official request for a turbocharged version (designated Cosworth YBB) capable of 180 HP on the street and 300 HP in race trim, was placed. Cosworth answered positively, but they put up two conditions: the engine would produce not less than 150kW (204 HP) in the street version, and Ford had to accept no fewer than 15,000 engines. Turner's project would only need about 5,000 engines, but Ford nevertheless accepted the conditions. The extra 10,000 engines would later become one of the reasons Ford also chose to develop a four-door, second generation, Sierra RS Cosworth.Silverstone Auctions said before the auction on Saturday that 'the attention to the detail of this car's maintenance cannot be understated' In August 1987 the Sierra RS500 Cosworth was homologated. Ford took pole position in all the remaining six 1987 World Touring Car Championship events and was first over the finish line in four of them. The works Eggenberger Motorsport team won the entrants' World Championship, although the team's cars were disqualified from the 1987 Bathurst 1000 in Australia for wheel arch panel irregularities. These had been deemed legal in every other race that year [5] however this deprived Klaus Ludwig and Klaus Niedzwiedz of the drivers' title. [6] [7] Eggenberger won the 1989 Spa 24 Hours. Old three-door ECUs (Level 1/L1) can also be problematic, generally supplanted by a Sapphire’s L6. A cheeky Stage 1 chip wakes up a Cossie, and shouldn’t detract from the car’s value.

Copies are common: Ford sold a vast range of development parts and it was possible to uprate to RS500 spec. Ford Motorsport part numbers begin with code 909. RS500 chassis numbers on the slam panel and beside the driver’s seat are WFOEXXGBBEGG 38600-39099; engine numbers (remove cambelt cover to see) are YBD 0015-0537.
