Hey, maybe a stupid question but here goes...
Ya all know the V-Tec engine in Honda's. From what I can gather it is like a "supercharged" engine or something. The "V-TEC" kicks in at a certain RPM's or something? I don't know. But anyways, is the Zetec like that, or is that just a fancy name for the DOHC engine(opposite the SPI SOHC engine.)? Just wondering, and I figured at least a few people out there have wondered this before. Thanks, Chris.

There's nothing "Supercharged" about VETEC either.
It has "variable cam-timing", which goes to a second set of cam-lobes at a higher RPM. No Forced-Induction, or anything of the sort.

Zetec has actually been around longer than vtech. Its basically just a name to classify the economy car engines.

Lessons learned in the development of the CVCC engine led to the development of Honda's Variable Valve Timing and Lift Electronic Control (VTEC) engine. First introduced in 1990 in the Acura NSX sports car, Honda's VTEC engine has been the foundation for many of Honda's breakthroughs in environmental technology. The VTEC engine can deliver high performance, as in the NSX, or high fuel economy, as in the Civic, or

Well... Not exactly. The ZX2 and SVT heads only alter cam timing. Modern VTEC alters lift and timing.

EDIT: Well.. you did say similar. That works.

<font size="2" face="Verdana, Arial">No car used VTEC or was badged with that name in the mid 80s. The official JDM Honda factory manual actually states that the very first VTEC engine built by Honda worldwide was a B16A put in a Integra RSi in April of 1989 (before the NSX in 1990).

But Zetec was the name used by Ford's racing engine (not at all related to the current Zetec badged 2.0 liter) used in formula racing back in the early 80s.


IOW, Honda was the one that twisted their technology (making it spell VTEC is a stretch of the imagination... Variable Valve Timing and Lift Electronic Control
) to spell out a catchy name like Ford was already using (also probably because it "sounds cool").
But lets face it, it really should be something more similar in name to Toyota's VVTL if they REALLY wanted the abreviation to just stand for the technology.

<font size="2" face="Verdana, Arial">The SVT Focus engine is still a Zetec. There is a new line of Duratec four cylinders coming to America though, but the modified Zetec in the SVT Focus is NOT one of them.

Edit:
PS: I HATE HATE HATE that. I went to go check out one of the RSXs when it first came out. And thats what the salesman at the dealer was telling everyone (including me). It has this VTEC-i technology that is like a small supercharger for the engine. Small supercharger? WTF!
I swear half the rice boys I talk to that swear that VTEC is the shizzy also don't have a clue what it does or what it looks like. It just lets you run two sets of cams. Typically if you run aggressive cams you sacrifice things like idle and low rpm power. If you run "mild" cams, you lose on top end. Cam changing allows you to choose between two sets of cam profiles (one for high rpm and one for low rpm) and cam phasing helps improve output a bit more as well by rotating the cams (what the SVT has on the intake).

"The SVT Focus is powered by a high-revving, twin-cam,four-cylinder engine with four valves per cylinder. The engine is based on Ford’s Zetec 2.0L I-4 found in Focus ZX3 and device directs intake air through four long runners below 6,000 rpm. Above 6,000, the manifold switches position to shorten the length of the runners, which improves peak power output."

From SVT's Website..

Not Duratec, Thats in the RS.

Yeah, its "teh ghey" though... the RS is still a Zetec engine, but they put a Duratec badge on it so that people relate that high performance Zetec engine with the new Duratec line of engines already being put in the base models.
