The Ford Sierra RS Cosworth was launched at the 1985 Geneva Motor Show and was the first Ford to wear the 'Cosworth' badge. Only 5,545 were built in order to homologate the car for 'Group A' Touring Car racing and were based on the three-door Sierra bodyshell but fitted with a 2.0-litre turbocharged engine, of now legendary repute. This power unit featured a double overhead camshaft opening 16 valves, and was force fed through a Garret T3 turbo and intercooler, giving a reliable 204bhp which resulted in a top speed of 150 mph and a 0-60 time of just 6.8 seconds!
The purposeful-looking Sierra RS Cosworth on offer here has been built with circuit use in mind. The shell has never been fitted with a sunroof and has been subject to a full strip, restoration and re-spray. It's fitted with an aluminium, multi-point roll cage, a biased pedal box, and the brake lines, fuel pipes, and new 'Motorsport' wiring loom are braided and run within the car. The dashboard is bespoke and carries a number of auxiliary gauges and a pair of competition seats along with full harnesses have been fitted. The car has been set-up on 'Gaz' coil-over suspension all round and the rear beam and trailing arms have been powder coated satin black. The brakes have been refurbished and built for competition use, and the car sits on Gold magnesium 7”x 15” wheels.
The engine is a Dave Brooks built 'Gp A' unit with a '200' cylinder block, lightened and balanced crank and rods, Mahle pistons and BD 14 camshafts, and has covered around 500 miles since new. Fuel is force-fed with the aid of the T3 turbo and the sparks are provided by a Group A coil and leads. The car has a heavy duty AP clutch and the gearbox and diff have only covered around 500 miles since their respective rebuilds. The engine is described by the vendor as being in “excellent running order” and the Dave Brooks Engineering engine build sheet is with the car. There is a twin side-exit exhaust fitted and an uprated fuel pump. The Diamond White paintwork is described as being in “very good condition” and the coachwork as “in good condition with minor scrapes and scuffs”.
This is a well prepared Cosworth that would make an excellent track-day car or could be developed further for sprints and hill climbs or turned into a full race car for circuit racing.
To be offered on Friday 24th February by Silverstone Auctions at Race Retro, Stoneleigh Park, Coventry. For further details please contact Guy Lees-Milne 07773776414
