D934UOO was first registered in January 1987 within a batch of six Boreham Sierra Cosworths, of the others - four being GpA and one GpN. Most famous of its sister cars being D935UOO which was driven by Stig Blomqvist in 1987 on the 1987 1000 Lakes and RAC rallies.
By the mid 1980s Ford were no longer competitive in touring car racing as the Capri was outpaced by Rovers Vitesse, amongst others. The Sierra range did not contain a high performance model and Ford Motorsport had spent very little time trying to develop the car.
Cosworth had designed and built a 16 valve twin cam conversion to fit the 2 litre Pinto bottom end which was intended as an aftermarket normally aspirated engine which could replace the BDA. It was Ford Motorsport Director, Stuart Turner, who conceived the idea of putting a turbocharged version of this engine into the Sierra. In order to homologate the car, he then persuaded Fords bosses to sanction the building of 5000 cars.
The Sierra RS Cosworth was duly homologated by the FIA in Groups A and N on 1st January 1987. The FIA rules at the time also allowed an evolution version for racing (but not rallying) if a further 500 cars were produced with a different specification. The RS500 featured an uprated engine with a stronger block, revised cylinder head, larger turbo and a special inlet manifold with eight injectors (only four were actually connected) plus a larger intercooler, revised ECU, modified rear suspension beam and different spoilers. Following an FIA inspection the RS500 was homologated on 1st August 1987.
