Ford has given the Zetec name to two different types of 16v engines. To confuse matters even more, Ford also badges some of their models as Zetec to denote that it is a sports version (usually with alloy wheels, sports suspension, spoilers, etc). A Zetec badged car therefore does not always have a Zetec engine under the bonnet! Zetec E - The original Zetec engine was fitted to Escort, Orion, Fiesta Mk3, Mondeo, Cougar and 1.8/2.0 Focus models. It has been produced in 1.6, 1.8 and 2.0 litre capacities. All engines produced up to April 98 use hydraulic followers, those built from May 98 were redesigned using mechanical followers. The con rods and pistons were also significantly changed with the later engines using a longer rod with a shorter compression height piston. These later engines are fitted in 1.8/2.0 Focus, Cougar and late Mk2 Mondeo models. Zetec S - This is the baby Zetec as fitted to the post 95 Fiesta, Puma and 1.4/1.6 Focus models. It has been produced in 1.25, 1.4, 1.6 and 1.7 litre capacities. These engines bare no mechanical resemblance to the Zetec E engines. Most tuning parts are available only for the Zetec E engine.
The Duratec HE engine is the latest 4 cylinder engine from Fords that, due to it's near perfect dimensions and characteristics, provides an ideal platform for a performance engine that can be modified with relative ease. Built around an aluminium block, these engines weigh around 92kg (less clutch and alternator). As a natural progression from the Zetec E engine, the Duratec HE is rapidly becoming a popular transplant engine for classic RWD cars and kit cars. We are therefore able to supply most conversion parts for such applications (as we already provide for the Zetec E), along with a range of modified engine components. This engine has currently only been fitted to Mondeo models produced after 2001 and is available in 1.8 and 2.0 capacities. A 2.3 version is also produced in the USA. It should not be confused with the Duratec V6 Mondeo engine or the new Duratec 1.3 and 1.6 SOHC engines that are being fitted to the latest Ka and StreetKa models (nice one Fords!!)
