Anyone here anything about GM turboing the Cobalt?

Heard a rumor over on ************** and was just curious, you guys would know more than them about your cars

BullDog71ss

There are a ton of rumors and speculations as to what GM has in store for the Cobalt, but none of us really know any concrete facts. Hell we're not even positive of the exact date the staged kits are coming out.

As far as what i could assume, they will not turbo the cobalt. They will probably turbo the 07 Solstice.
I think the cobalt will always be the supercharged car, and the new solstice will be the turbocharged car in GM's assortment.

As for the aftermarket, i can almost guarantee that there will be turbo kits for the cobalt.

The same speculation happened with the mini-cooper-S. Didn't happen though. That is kind of like saying do you think dodge would have supercharged the SRT4? A Car manufacturer wouldn't change a setup like that so soon into a car's debut. Maye the 2nd gen cobalt will have a turbo, but GM is really known for supercharged cars.

hell, i like bein diff with S/C...... every 1 else has Turbo's

J.D.

There's a great article over on .com about why GM went with the super. pretty much scwelches the super/turbo argument as far as from a manufacturer's standpoint. I'll link it here in a sec....

The supercharger is way louder than the srt4's turbo (except maybe if you have the blow off valve) besides I like the whine better. I used to like the turbo's whoosh but now i like the s/c especially with an intake, you can hear that thing a mile away

SRT-4Scott

Probably because the srt4's exhaust drowns out the sound of the turbo a lot. I just put an intake on mine and the turbo is very loud now. When I test drove a cobalt I actually couldn't even hear the supercharger. But I only took it up to 4500 rpms.

GM will turbo the Ecotech in the Solstice. So I don't see why they COULDN'T just put that motor into this car. But who knows if they will. I guess it depends on how well that motor does with the turbo and performance specs.

Stock intake is VERY restrictive and yes you won't hear the supercharger until a real intake or the intake mod on the stock airbox is in place.

I think GM went in the right direction by Supercharging the SS S/C instead of Turbocharging it. With the S/C, the power is always there, no waiting for any turbine to spool and no lag whatsoever. Its practically always on the boost, which gives much better driveability than a peaky turbo system would.

Superchargers also require less maintenance and tend to last longer, and you don't need to give them a cool down period after hard driving as you have to with turbos.

And last but not least, Superchargers definitely sound better

Drewfu$

You guys need to understand that with todays turbos, lag is practically eliminated. It usually only comes with turbos that arn't sized correctly to the engine.

They are much more effecient and will always deliver better power.

A while back, some magazine (HotRod or Enginemasters) did a build using the same engine, but running it with a turbo, centrifical blower, and roots blower. It was a very fare comparison, and the turbo won all the way around, even on torque.

thats a good report but its very biased on the side of the SC...i'm a big fan on the SC but there are some drawbacks to the SC such as drag and such on the moter...theres gotta be others....good repot none the less

Saab turbo 2.0 ecotec- 221lb-ft tq @ 2,500rpms
Cobalt S/c 2.0 ecotec- 200lb-ft tq @ 4,400rpms

The word is the direct injection 2.0 Turbo ecotec will be used across the board . 07 Solstice GXP , 07 Sky Redline , Cobalt SS and Ion Redline by model year 2008 with the Cobalt "major refresh" and the , what supposed to be totally new (Ion<- which has been put on hold as of 12-1 ) 2006 is now the last year for the Ion .

Etec turbocharger wastegate?
:P

SRT-4Scott

It's mostly a personal preference. Which can be argued about all day. Put it this way, we are both happy.

celicacobalt

i love turbos

Spastic Chicken

I want both :drools:

Where did you hear that? I have only heard of a cosmetic re-style in 2008 on the car. I can't see GM just releasing staged kits for the LSJ only a year and a half before discontinuing the engine. I would imagine that the LSJ is here to stay, but could be wrong. 2008 would be the earliest I could see them making a change though.

Are you sure that is the same engine as the 2.0L Ectotec supercharged. I don't think it is, but I could be mistaken Torque peaking so low (2500 RPM) likely means it drops off in the upper rev range. I'd still take the Supercharger in my opinion. Lasts longer, lower maintenance, and sounds way better. Just my opinion though.

SilverSS/SC

There are several insiders including a few from GM that post on sites like Cheers and Gears and the future vehicles forums on CamaroZ28.com . Ive been around both sites for years and the few on there that actually do know whats going on arent BS , period . They give out info when they can , unless the info is embargoed then they wont say a thing . By saying major refresh , I didnt mean an all new car . It is supposed to have a pretty big refresh for only being a 3 year old model though . If you start hearing GM adapting direct injection with the supercharged version the 2.0 , then I may be convinced its here for awhile , right now Im not . The DI 2.0 Turbo will offer greater fuel mileage and cleaner emissions with greater HP and Torque . FWIW - the DI 2.0T is totally different than the current 210 hp 2.0T in the Saabs and Opels . GM had to overcome the issue of emissions with the staged kits , thats "supposedly" why the release is taking longer than expected . "If" GM chose to up the output of the LSJ engine 3 years from now , I dont think the combo of fuel mileage , power output and emission legality would bode in its favor . With the announcement of DI 2.0T , that pretty much spells out how GM is gonna efficiently offer high output 4 cyl engines . The didnt choose a turbocharger for the kappa cars because turbo's are cooler in the eyes of the tuner market , if thats the case the Ion and Cobalt woulda had a turbo from day 1 . For a company like GM , its not as simple as do we want a blower or a turbo . Emissions and economy rule in their world .

Also , GM performance parts has nothing to do with future product .

the solstice GXP is being shown for the first time at the LA auto show in a couple weeks

and is susposed to be the direct injection turbo

and from what i know the 2.0 s/c motor was to be short lived from day 1 , all theough they should have just used the complete 2.0 turbo motor from the saab 93T high boost turbo

Adirondack_Cobalt

Forced Induction makes me smile... the boost hits, the tires break free, the car begins to pile on speed as the ******* speedometer needle heels over like its possessed... oh yes.
If you've never had a car with a turbo (and I'm not talking your mom's volvo), it's a blast.

I've had a couple...
If I keep this Cobalt, it's getting the turbo treatment!
