Product Information
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.

  • 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

TEXT_OF_5_STARS by Per Aasterod
"I can recommend Vivid Racing for everyone.....because they are pro`s in any aspect.I am very happy with customer service from this shop. Thanks"
TEXT_OF_5_STARS by Bill Leslie
"Yes thanks guys, I was very impressed with the service and delivery to New Zealand in the first instance as my previous review said. Very happy to say that now that the Bilsten HD shocks have been fitted I just don't know why it took me so long to do a remarkably easy and worthwhile an upgrade. If any second generation Camaro owners are reading this, don't hesitate this shock is the single best thing you could do to the front end handling and at a fair price Thanks again,"

"Orders are simple and intuitive, good and clear interface."
TEXT_OF_5_STARS by Chester Tech
"With a lot of other Online Stores not able to shipped an exhaust system APO AE Vividracing was a blessing for me. They were able to give me the lowest price and shipped the items for FREE. Arsha was very helpful and very pleasant to talk to and always responded to my emails quickly. Ultimate Customer Service Achieved!!! Thank You!"
TEXT_OF_5_STARS by Michael Demayo
"I think the best thing about vivid isnt the competitive prices, honestly its the customer service. When you drop hard earned cash, you are going to want to know that you can trust the people handling your order, especially after the order is placed. Ahmed was awesome the entire time. I literally have an email string of over 50 email messages between him and I. He always did the best he could to provide me information on my order, and i totally appreciated it every time. I suppose all i am trying to say is, Vivid rocks, and so does Ahmed. The best prices alone doesnt mean squat if there isnt anyone the customer can communicate with, luckily then vivid has both competitive prices and excellent customer service BEFORE, DURING, and even AFTER your order is placed."
