I DOUBT IT. ZETEC IS JUST A NAMESAKE.OH AND BY THE WAY. THE CAPS LOCK BUTTON IS ON THE LEFT SIDE OF YOUR KEYBOARD, NEXT TO THE A KEY.

just joshin wit ya man, but really, I dont think theyll do that anytime soon

actually there were zetecs in the contours that had intake cam timing i believe. heard about it a while ago, don't remember where, but i think it was decided that it wouldn't be worth it to swap heads.

The ZX2 has exhaust cam timing... which supposedly was not a power mod. I suppose some Contours may have had it as well, though I've never seen one.

Besides... the "magic" of VTEC (somebody shoot me...) is in the lift, not the timing.

I'd rather have Valvetronic though... variable timing and more than two positions of lift... enough variation to do away with the throttle body... THAT is technology.

Well, the SVT Focus had variable cam timing on the intake cam but that's about as close as the Zetec ever got.

That and the dual stage intake manifold gave the SVT a somewhat similiar effect as VTEC does in the Hondas. But it's definitely not the same.

i guess it coulda been the escorts i was thinkin of, i knew that a previous model car that used zetec had some form of variable intake timing.

you guys really have no clue what Vtec is do u? i love when peple say i can feel my vtec kick in, or i want the 20hp boost when vtec kicks in,
you dont want to "FEEL" vtec, if you have your honda tuned right it will be a smooth transition to the different lobes of the cam, and you wont FEEL anything, but you will hear a difference in how the exhaust tone is...
If you have vtec or vvt in a honda or toyota and you can "feel" the cams swithing to the higher performance lobes, then you have major problems, and your car is very very poorly tuned.

oh, and vtec is variable valve timing, which means the cams have more than one lobe profile on them, and at whatever rpms your vafc turns ur vtec on, it switches to a higher lift higher rpm profile for making power in high rpms... how do you think hondas rev to 8k and are streetable?
Hondas are for pussies... be a real man, buy some big ass cams to pull to 8k+ and have a huge lopey idle,

and VCT is no where near vtec, it is nothing like it, and is pretty much useless, VCT was NEVER put on a car for a power adder except the SVTF. it was for emissions on all other cars.
And VTEC on SOHC hondas is also usless, its for emissions purposes... nothing more...

Actually... most of us DO know all that...

But as for a smooth transition... The center lobe is either engaged or not... It is binary.

You can't smoothly engage the center lobe.

..and "variable valve timing" has nothing to do with other profiles.. "timing" means advance and retard only... variable LIFT is what the center lobe does.

Well guys, I don't know about us not having something like VTEC because my Zetec controller is set to kick Zetec in when I start the car.

Also you will feel the big lobe switch over when you reach the set rpm on Vtec engines. On DOHC vtec engines its noticable and sounds different because it changes intake/exhaust cam lobes. On SOHC Vtec engines you can barely notice it, only a slight change in sound because it only changes the intake cam lobes, and is for emissions/gas milage.
When someone with a midly modified(intake/exhaust/header, that kinda thing) Sohc Vtec engine says they vtec pulls them to 9000rpm please slap them in the face.

LOL!!!20hp. boost...
Image
that would be in motor terms larger lobes on your camshaft allowing motor to rev higher...it's not like nitrous....you wont all of a sudden at 5 grand or where ever it switches feel a sudden jolt..it allows you to have a higher peak horsepower and be able to use it effiecently<<<<i think thats how you spell that? Anyways if you want 20 extra go buy a exhaust and intake....i especially like the guys in the honda's who have to have the VTEC light come on at the higher RPM when it switches lobes so they can go LOOK MY VTEC IS ENGAGING.....wow....i'm impressed....how about LISTEN MY TURBOS BLOWING OFF!

From the factory, the H22A4 in my Prelude sounds and feels different when the VTEC engages, even when it was 100% stock. That does NOT mean that it is poorly tuned. Put a set of stage 2 or 3 cams in a DOHC VTEC engine and you're definately going to feel and hear the difference. I have never heard such a statement about quiet=correctly tuned, either.

Now i-VTEC is a different story (kinda). the switchover is much less noticable.

As far as VTEC being new technology, I guess it was in 1991 when it was first introduced.
