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.
The Cosworth under drive pulley will improve engine response and help maintain ancillary component speed in race applications. Available with a standard style ignition trigger disc to maintain proper engine timing or without for custom applications.
