Cosworth has been modifying Ford four cylinder engines since 1959 and the practice continues with the Ford Duratec/Mazda MZR. The Duratec/MZR was designed as a replacement for the Zetec engine and was developed as joint collaboration with Ford and Mazda. The lightweight engine features a cast aluminum reinforced block and main bearing girdle that help reduce vibration and improve overall rigidity.
The Duratec is an excellent, affordable building block for high performance use and perfect for Lotus Seven inspired sports cars, rally cars and racing.
An efficient cooling system is essential in maintaining the engines performance under all operating conditions. Although the complete system will depend upon the individual installation, it is vital that the water pump and thermostat are working as designed.
Questionable parts should be replaced. For sustained high speed use, a low speed water pump pulley helps to reduce pump cavitation and maintain a constant flow of water.
