So...Zetec is not just a name and its not your average 4v 2.0L.

Your talking about the SVT Focus. This is NOT the standard Zetec motor or the standard Focus. It the same as saying the V8 in the GT is the same engine as the V8 as the Cobra. The SVT is different. Even the ZX2 with it's VCT didn't have long/short runners, so that alone is way off. Like every $12,000 ZX3 has long and short runners. And a SVT motor. The Zetec is standard in the ZX3. The non ZX2, SVT zetec is just your standard pentroof 4v 2.0L 4cyl engine. No VCT, no short/long runners, no VVT, no extra anything.
In fact the Duratec motor that replaces it has a much better head design. It has the potential to flow much more.

uh i didnt have any sources, i just said that it sounded pretty true. we were discussing it at an SAE meeting and the question came up again about the zetec and its ability to maintain 80% of its power at any rev(something that has is static throughout the zetec family).

ZXx = ZX2 ZX3...etc
Ghia= Ghia Mondeo..Ghia Puma...etc

sorry im just trying to figure it out.

[drdaveleister]

and just so you know were just a bunch of m.e. students talking and trying to figure out the little things...thats all

duratec is next. heh heh heh

VTEC is how Honda controls their cam lift and duration on some of their engines. VTEC stands for Variable Valve Timing and Lift Electronic Control.


Zetec has absolutly nothing to do with cams and does nothing but denote which family of engine is in the car. ALL Zetecs are double overhead cam engines, NO SOHC.
The Zetec name is no different than the Fe engine family or the Winsor engine family, it's just a name.

Base trim focus zx3's are available in a 1.8 litre SOHC.

i have a 1998 Zx2 with the zetec /w vct and im trying to locate a good parts website for my mini american muscle car any help?

[AlaskanWrench]

also when i look online alot of sites say that a part will work for a zx2 and zx3 what exactly is the difference between the zetec in the zx2 and the zetec in the zx3? Besides the valve cover color.

fordesigner obviously knows what he is talking about. quit trying to test him, even IF he wasn't woking for ford, he's still educated about what he is saying

anyways, what did they improve with the duratec? i wanna hear more about that.

Ok, here you can go through,

1. Zetec is a trim level offered across numerous Ford models. It fits between the more basic Studio and Style models and the range-topping Titanium line. Zetec is available on all mainstream Fords and costs around £3,000 more than the most basic models.

2. This is more powerful than the larger 1.1-litre engine, the 99bhp EcoBoost is perky and responsive, achieving 0-62mph in a very respectable 10.5 seconds. A 113mph top speed makes it fuss-free when cruising at motorway speeds, too. Passengers will enjoy travelling in the Fiesta Zetec.

3. There is a big difference between the ZETEC and VTEC. The main difference is valve timing and w/ i-VTEC they also control cam timing. Honda has the upper hand when it comes to high performance engines. When you can have a 1.6L engine produce 160hp and 111 ft.

4. There is also a differences between ZETEC and VTEC controller as like as their pattern differences.
