General

The 16 valve Cosworth engine presents the key element of the Sierra RS Cosworth. It uses the engine block from the proven Ford OHC engine but is completed with a host of new components and systems
such as

• The new cylinder head with its two camshafts to actuate the 4 valves of each cylinder
• A water cooled Garret turbo charger
• A Weber electronic fuel injection system and
• an ignition system made by Marelli.

However, in addition to its unique power plant, Sierra RS Cosworth houses a host of other new or modi*fied components and systems a Service Technician needs to be familiar with and these are

• A close ratio 5 speed transmission
• New clutch and driveshaft
• Limited slip differential similar to Scorpio
• Revised rear axle mounting

Revised front and rear suspension with power steering and specially tuned shock absorbers and springs to meet Sierra RS Cosworths demands on road holding and road adhesion

• Teves ABS braking system similar to the system used on Scorpio.
In addition to this exciting list of features the interior has been redesigned to match the vehicles sporty appearance and to provide the driver with the environment required for a car of this class.
