for those of you that havent seen or heard the 07 solstice.. 2.0 TURBO 260hp 260tq 47% boost in HP almost half that power is through turbo. so basically what im saying is we need an SST cobalt with some 260hp in it...so much more power options with a turbo 400-600hp range would be a breeze turbo change, engine build, 3" turbo back and you could very easily make 375 with just a hair bigger turbo and some more boost....just thought id throw out some FYI to get everyone dreaming about it, cuz i sure as hell am that would be so insane.

 

Chevy is scared to turbo anything after the Callaway fiasco. It'd be awesome but I'm not holding my breath. I bet that Solstice ends up selling for $5k+ over sticker.

 

The reason the did turbo it was because the 2.0 SC engine wouldn't fit in the engine bay...so they transversly mounted it and put a turbo on it. But as far a GM puting this motor into the cobalt....NO. The body would have to be reworked to accomodate the turbo, and a new transmision. I just dont see them putting in the time and money.

 

Rumor has it that gm is searching for contractor to build the head and block for the 09 cobalt because they want something stronger because they want to release it with a 350 hp engine under the hood. Granted this is just rumors thus far from people i know who work for gm and who are bidding for this contract. We'll say how it plays out.

 

Exactly why does GM have to get up on it? I mean you DO know that the Solstice IS a GM product right? So from a manufacturer's standpoint, why would you put an engine that's just as powerful in a car that you are charging LESS for?

That's like cramming in the 7.0 liter V-8 from the Z06 into the Aveo. GM's thinking is if you want the 260 HP out of the 2.0 liter ecotec, buy it wrapped around a Solstice.

It would be nice if it was like the old days where you could buy whatever chasis you needed and just plugged in any engine. If GM were to plug in the 260 HP 2.0 into the Cobalt or Ion, it would only hurt the sales of the Solstice and if you were a stockholder, would you rather they put the engine in a $20,000 car or a $30,000 car?

 

Solstice GXP = $24,995 base MSRP ......if there priced gouged , thats a dealer profit , not a GM profit .

Its not the packaging !!! . The exact same engine bay in the Euro Opel Astra our Euro twin , uses a 2.0 turbo ecotec with a front mount intercooler and a 6 speed trans .

 

Good luck getting the GXP for that price. Trust me when I say this, GM knows exactly what its doing when it offers a 205HP engine in the Cobalt SS and a 260 HP engine in the Solstice GXP. Like I said before, it would be nice if we can order A La Carte, but don't hold your breath.

 

That is not GM's fault . They can only set the suggested sticker , they cannot legally control what a greedy dealer will sell any car for . The Cobalt and the Solstice are not even remotely in the same markets . If your theory applied , who would pay 22-24K for a loaded 2.4 solstice when they can get a faster more powerful SS/SC for less . Or hell why not go cheaper yet and get the same 2.4 in the NA CObalt SS . The "Corvette Rule" left GM when Ron Zarella left the door , and someone hell bent on a Soltice or sky are not gonna even wince at a economy car like the Cobalt .

 

another thing that you guys need to take into consideration is the fact that GM wants the coblats to compete agianst evo's and STi's that is why they built it so when you look at those other cars prices all GM will do is raise the price so that they can be in the sport compact racing market to

my 2 cents

 

The Soltice/Sky sales shouldn't be effected by the 2.0T in a Cobalt. They are roadsters and the Cobalt is a sport compact. Two completely different markets

 

Huh??? GM doesn't want to compete with the EVOs and STIs, nobody does. Mazda tried and failed, Ford is the only one that has a chance to compete with the STIs and EVOs.

 

Makes sense...



actaully, not so much.

 

Granted, but if you were a prospective Solstice GXP buyer why would you buy a car that has the same drivetrain/engine specs as a Cobalt SS? GM has to distinguish its various cars and there are different levels that GM has to place each car or else it finds its competing within itself. The levels that usually define a market are Luxury/Sport/Exclusivity. Would be nice if GM could make just a handful of vehicles that meet all the different tastes out there, but you have to take into consideration that GM is a company that has to make money first and foremost.

For instance take the Cadillac STS-V. What if GM packaged EVERYTHING on the STS-V rebaged it as a Cobalt SS? It would sell at great volumes if it kept the $20,000 range (for the sake of argument). Now why would anyone want to pay the $50,000 plus for an STS-V if they could get the exact same car at a Chevy dealership for $30,000 less?

I personally don't care that the 2.0 Cobalt/Ion isn't turbo charged, makes it all the more sweeter getting numbers close to if not better than the stock 2.0T but GM has at least given us a nice platform to tune for greater power.

 

It also uses a different turbo set up than the Solstice. The top Astra only makes about 200 hp.

 

Because is a rwd roadster, not a fwd economy car....As others have said, these are 2 ENTIRELY different classes of car and groups of buyers.

 

No thanks on the turbo. I hate lag, I like INSTANT power and response. I also like a very broad torque range, not just peak power and torque. Go look at Fast06SS's dyno sheet, and you'll see what I mean. Oh, and turbo's DO have lag, regardless of how small you try to make it seem.

 

Thank you.

The STS-V comparison is not even close to the topic at hand. Now comparing the (EDIT: I meant 04) 05 Z06 to the 06 CTS-V is more appropriate. Both use the LS6 motor and MSRP is similar, but they are geared for two completely different markets.

I really don't care if the turbo comes to the Cobalt or not. I prefer S/C's. Although it would probably sell better in the tuner market.

 

Well, it was a little more of an exaggerated comparison mainly to prove the point that GM wants to differentiate between the GXP's powertrain and that of the Cobalt SS. Its called Brand Management and has been around before most of us were even a gleam in our daddy's eye...........

 

I beleive GM will go 2.0 Turbo for the delta chassis. They just have to rearrange the plumbing. Makes sense to have one F/I 2.0 Ecotec and not two. Besides the LSJ is assembled in Germany and the 2.o Turbo in the US--they can consoidate production facilities.

It would not canabalize Solstice GXP sales at all. This is just crazy reasoning.

If I want a Solstice...I want a 2 seat convertible car with almost no storage. People will not go, "Hey check out that Cobalt...its 5K cheaper!" You buy a Solstice for a reason and the Cobalt canot full fill the same requirements.

 

the 06 corvette zo6 uses the ls7 not ls6. unless of course you were talking about the base model car. didnt mean to nitpick but i had to point that out

 

Everybody keeps saying the Soltice combo wont work , and yes it is likely that the dual scroll turbo will not fit . The FWD cars would have a variation of GXP engine , at their own specific power output and specific plumbing Opel is still using Family 1 ecotecs and is due for its update about the same time the Cobalt and G5 are , the next delta powertrain update the US and Euro's should be using the same powerplants , by Bob Lutz's own words that Euro and US cars from now on will share everything mechanically possible for cars on the same chassis's . Opel already refused the LSJ once because of the supercharger ......preferences aside take that for what its worth .

 

Yeah I know. I meant to say the 04 and accidentally typed 05. There wasn't an 05 Z06.

 

gotcha

 

What you have to realize is that the SC takes HP to turn it. By removing that and adding a turbo, you effectively raised the HP 30% just by removing the hp drag created by turning the SC.

 

And then don't forget to mention that you have to wait for enough exhaust to build to spool up the Turbo. From what I understand the turbos of today are much better at this and maybe (slight maybe) its better for the FWD cars since too much torque early in the RPM range is self defeating (i.e. wheel hop/spin). I personally would've liked to see what kind of HP GM could've achieved by slapping the supercharger on an engine with similar displacement on the 2.4T from dodge. Still when you think about the HP per liter displacement of the GM 2.0 versus the Dodge 2.4 its quite amazing.
