Engine Dual VVT-i

Dual VVT-i

WHAT??...read this...

http://en.wikipedia.org/wiki/VVT-i

towards the bottom...what does that mean? is the engine twice as powerful? twice as fuel efficient? two times better?

anyone heard of this?

it just simply means that the change in timing of the intake and exhaust cams will be seperate, rather than both cams changing together

Dual vvt-i is not really new. Toyota used it on the newest BEAM 3S engine in Japan already. And now in the new Avalon too.

It may not be new, but I still want it!

i got dvvti yo.
it makes 2000hp.
jay dee emm

its also what they ar putting in the newer V6 Tundras...

Isnt that in the IS300 already??

Its going into the new Camry for 06. And its going into 1 or 2 others that use V6's.

the dual part means that it's going to be on two heads instead of just the one. they'll both most likely kick in at the exact same time, just need two units to run it on a v6...

edit - vvt-i may be in the is300...but it's not the dual vvt-i since the is300's run off a 2jz-ge non turbo straight 6 motor...

hmmm interesting damn I want one lol

No, no our 2JZ-GE IS300 but 3S-GE Altezza in japan.

"so how much would it cost me to swap my vvt-i to dual vvt-i"

Wrong. If that were the case, you would see all the V6's with VVT-i called Dual VVT-i, but they're not. Unless of course the V6's that are out now only have VVT-i on 1 intake cam on 1 head based on your terminology. Dual VVT-i means that it has VVT-i on both intake and exhaust cams, 'nuff said. How Toyota manages to control it on a V6 setup I don't know.

IS300 = 2JZ-GE = VVT-i

the new avalon is a beast

Forgot that the new GS300 has Dual VVT-i as well.

new IS will have dual vvti but toyota plans to put it in all cars

2 solenoids = dual solenoids (one solenoid per cylinder head)
2 exhaust headers with non-intersecting pipes = dual exhaust




just a theory
