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 Duratec CNC ported Big Valve cylinder head is the result of countless hours of development and testing. Starting with fresh large port castings, Cosworth precision machines both intake and exhaust ports to maximize flow. They then reshape the combustion chamber to un-shroud the the larger stainless steel valves.

The head is then assembled using hi-rev tapered springs along with new valve stem seals and retainers. This cylinder head is the key to making big power and will flow enough to support 300bhp.

Features:
  • New OE Large port castings
  • Machined port finish
  • Knife edge port dividers
  • Machined Cosworth Logo and serial number
  • Oversize intake and exhaust valves
  • Reshaped combustion chamber
