I was at the dealership Saturday to pick up some parts, and while I was waiting for them to find my stuff I picked up some brochures about their 06 line. Upon reading about one of the cars that had the latest version of the Ecotec, I noticed it had VVT on the exhaust cam. Last time I checked, GM built their little miracle motor without any VVT technology whatsoever. Are they finally starting to see the light? Is it possible that GM has finally realized that they're going to need this kind of technology to be competitive with Japanese companies? Granted, if that's the case, they've sort of half-assed it, since VVT on BOTH cams would be way better, but... Is this a sign of things to come?

are you sure it was the eco?
the pontiac vibe is made by toyota and has VVT-i equpied.
Injection is nice but id rather be BLOWN!
The 2.4 does its the only one that I know of.
Semper Fi SAINT. May you rest in peace.
the 2.4 Ecotec VVT started with 05 models in some cars.
I was a retard, and now I'm permanently banned.

It wasn't the Vibe. I'm already aware of what they have, it's just a Matrix with different front end treatment. But I was at the Chevy dealer, maybe I should have specified. I'm thinking I was reading the HHR specs because they had one in the showroom and that's why I picked up the brochure. It just seemed strange because everybody said the Ecotecs don't have VVT. So maybe the aftermarket will start offering controllers like those for VTECs. I honestly think the Ecos would benefit.

The only thing Im sure of is that the solstice will have the ECOTEC LE5 with variable valve timingon both intake and exhaust cams.

Maybe true, but if it's such old news, then why does everyone say Ecos dont have the technology? I read another post a while back, someone was asking how to control the VVT on an Eco, and he was promptly told Ecos don't have VVT. That's why I posted this thread in the first place, because apparently, they do. Personally, I'm not a GM guy so I don't keep up on all the latest.

i think that guy needs to actually do his homework before opening his mouth next time. i sure hope someone shut him up fast.
the 2.4 eco vvt is both intake and exhaust
im not sure on the 2.0 direct injection turbo motor , but im sure its both intake and exhaust also
and from cas's post , its in these vehicles

great, now where gonna be seeing Vtech Controllers in GM's now
Personally I could care less for the VVT, VVT-I, Vtech, Ect. Yes, its a nice little boost around 5grand, but i get far more statisfaction beating a Vtech equiped honda with out any type of electric/vaccuum valve timing
...
the vvt in the 2.4 only changes the cam timing
and works at all rpm , it does not turn on and off like the honda vtech does .

that would be because no J-body equipped Ecotec has VVT..if he was told that they do not have VVT it is because no cavy or sunfire does and since this website is directed toward j-body's not delta, or kappa platform cars it would make sence why he was told the eco did not have VVT, the 2.4l VVT in the cobalt ss, the ion, solstice and HHR, and all the others has been out for a few months now..hell there was a HHR at the smallest dealership in town back in August when I went to my grandparents cabin. Its old news, and does not relate to the j-platform ecotec
Man, there's no reason to be so hostile. I understand fully that this is a J-Body site. The name of the site is a dead give away. If you want to flame me, go right ahead, that seems to be what things have been lowered to around here as of late. J-Body or Delta, Kappa, or whatever, that wasn't the reason I asked. Granted, the J-Body isn't even a platform still in production, but since there are a lot of people here who want to swap an Ecotec into their J, it IS, in my opinion anyway, a valid question. Maybe you don't value my opinion or this thread's topic, that's fine. I'm not asking for your approval. If there's an Ecotec available with that sort of technology, it seems to me it would be a better swap than an Ecotec without it.

and would you all please stop comparing vtec to vvt. they are 2 completely different animals
vvt rotates the cam back and fourth , retarding and advancing, to maximise preformance in all situations. so you can biuld a top end motor and make it pull better on the low end or make a low end motor and have it have more pep up top. basically take the cam and twist it back and fourth, that is all (side note: the 05+ 3valve mustangs have this to)
vtec kind sorta does the same thing in a way but in a much different fasion. and it is more like an on off swich. each cam has 3 lobes per cylander. 2 are the smaller, torq makind emissions passing lobes. the 3rd lobe is the big nasty one. when you hit the right rpm at the right oil pressure it send oil press to the 3rd lifter to activate that cam lobe. this only really adds lift and duration. but does not advance or retard the cam anything like vvt
personally, I like vvt better becaouse once you get into tuning it this will allow you a whole new window of preformance tunability
