Hey, So I was reading not to long ago about the Variable Valve Timing compared to the non VVt head on the 2.2 eco. After I read about this, I was wondering if I needed the VVT head, or do I just need the cams/gears/rockers/lifters?
I have a head I'm rebulding now and If I can use the same exact head, just need the VVT parts, I'm for sure going to build it as a VVt head.
Thanks for any input!
how are you going to control the VVT, by magic?
Well, what else would I need? Or better yet, can anyone show me the path to go to read more about this subject?

You need a way to control it partner.
Not gonna happen without an expensive engine management system
What kind of management system, who sells it? because I have cash to throw down, like i said I'm rebuilding this head right now. now if we're talking about a grand....then ya its not worth it, but ya
Again why? Its not VTEC and will never be VTEC. Just port and polish another head, toss in a set of stage 3 or tri-flow cams, and tune it. You'll get better gains with less headaches.

try more than that.
this is not a honda VTEC engine.. it doesn't work the same way.
VVT phases the cams, it doesn't add lift. VTEC (the proper one) engages an entirely different lobe on the camshaft that has a lot more lift, and duration.. basically switching from an economy cam to a race cam on the fly. The way its controlled is also relatively easy.. an electrical solenoid.
don't waste your time fixing what isn't broken. Port the head, upgrade the valvetrain and put bigger cams in it and be done with it. The VVT swap is retarded, and impossible with out an ecu that can control it (meaning a complete rewire of the car, rewire of the engine, and an entirely different ecu out of another car, either the solstice 2.4 or the cobalt 2.4) and since GM's VVT tends to bend valves when the cams get upgraded by altering the cam timing, you're thinking your way into a corner.

IDK about stage 3, but yeah this is your best bet. And with an upgraded intake and full exhaust, you'll get even better gains

a good quality built up head is gonna cost you over a $1000 by itself, a good valvetrain alone is about a grand.
Thanks for the input guys, I didnt know it would be such a pain, just looking for more HP for something easy, but this isnt easy. BTW any great sites to start finding good quality parts?
There is no easy ways to get HP, no magic box or gizmo... And if you get more hp, there's no way to make your car still behave and sound like a stock one. More hp usually makes your car louder, more vibrations and harder to drive...but still people hope or think maby there's some magic way to have it all, comfort, stock sound and drive.
Don't buy from MANTAPART!!
No, I dont care for the stock form really, I want a nice street car, whether its rough driving or not, I'm use to bad roads, or a bad ride. Thats not the problem, and I generally love cars and power of great machines. Thanks though.
