a turbo is cheaper than a normal blower... so this could make sense, it would probably also be a little be quieter... better yet. also, a turbo can be easier on gas as it's pretty simple to computer control the bypass valve these days and keep the boost at cruise speed right around ambient.
VVT and direct injection... these are a lot more money. will the turbo savings out weigh the cost of them? i have NO idea. my guess would be that since the 2,4 is more common now than a year or two ago, you may have a decent shot, but... i dunno.

Not to mention the fact that they'd be basically throwing their money that they put into stage kit R&D out the window, as new ones will surely have to be developed. What would make aLOT more sense for GM to do, would be to come out with stage 3, similar to the SRT stage 3, which would include a new blower, that is efficent up to a higher PSI....twin screw perhaps. If GM keeps backing the Cobalt as their tuner car...the aftermarket will surely follow. However if the 2008 Cobalt comes out as a turbo'd car, this will really hurt the aftermarket support. Aftermarket companies spend money developing their products too, it does them no service to have to totally re-design their products every 2 years because <insert car company here> has drastically changed their drivetrains.

They can't just toss the Solstice engine in the car...

you may be right, it's all just a lot of "i think" s right now. more than likely, the car will stay the same over all. the only real change i could possibly see is the adding of VVT to it. if one were to open the bore up a bit, and add VVT, i'd think it would be a drastic power change... but more than likely, the motor will stay 95% the same.

Went to the "HIN"(Hot import nights) this weekend and saw the gm rep there .He said there is a stage 3 kit comeing this fall but the bad thing about that kit is that u will lose the air conditioning in ur car .Dont ask me why but that is what he said .Plus he gave me a book on how to build my engine for 260 all the way to the built proof 1400hp motor .Its all in one book all the parts u need and where to get them even if gm don't carry it .

hey
I think its not going to be worth it or could be a lie but then again the solstice gxps are turboed so u never kno. Our cobalts will be modded by then to smoke the 08s so its all good plus i think a supercharger is just cooler then a turbo

Since still 1 year away we will just have to see what GM has in store.

1) If the Cobalt SS goes turbo, I can pretty much gaurantee that it won't be called a "Cobalt SS Supercharged", but instead "Cobalt SS Turbocharged" (or something similar). I know GM is stupid, but even I don't think that they are that dumb.
2) The engine in the Solstice/Sky is a 2.0L Turbo. It is basically the same engine as the LSJ except it is turbocharged and features variable valve timing and direct injection. The 2.4L is a N/A engine that is the same as in the Cobalt SS and Pursuit GT.

I have driven a lot of different cars, with varying drivetrains and power levels. A stock SS/SC definately makes somewhere between 200-230 HP stock at the crank. No more, no less.
