Just wondering...is it possible the reason they only do the supercharged ver of the 2.0L Ecotec is because it simply won't fit in the Cobalt because of the way they would have to run the intake/intercooler back to the front of the car??

Consider this pic of one:


Or this one without showing an intake reroute:


Maybe its just because there won't be any room...certainly there is no room to run stuff on the side of the engine where the belts are...

Engine compartment:



The supercharged version is much more compact, since the SC is up with the intake...

Of course the piping will need re-routed since its going into a fwd instead of rwd and will have to take into account the tranny being in the engine bay but nothing major.

Forseti

Its pretty major...if you are standing in front of the engine, the only potential place to route stuff is over the top, or on the right hand side...

The top would probably require a raised hood...probably not going to happen on a production car. Even so, its probably not good to run intake work over the top of the hot engine....

The right side is already filled with stuff! It would require a considerable rework of the car's electrical routing...

GM may be thinking is cheaper just to leave things alone....if the SS development group doesnt' get a lot of money to work with, that may be what happens....

Unless there is a major re-design of the Cobalt the turbo will never happen. There are some here who insist it's going to happen but I doubt it.

Hahn Racecraft did it on a 2.4 why would it work on a 2.0?

doesnt necessarily need a front mount. they could always run a topmount or sidemount.

Hell you could shoe horn an LS7 in there if you wanted too but it would take tons of cutting and fabbing. Yes the turbo ecotec could be done but it's going to take some rerouting of the plumbing and other things too.

You can run a turbo setup... I was looking into making a kit myself.. looks like plenty of room to do it... route the intake from the rear of the engine on the turbo... around to a front mount on the passenger side run the return piping up where the stock intake comes through and if you have the ss/sc run it right to the t.b. (I'm still gonna keep the meth injection to help with temps) if you want to keep it twincharged that looks like the only way to do it.]

After seeing the new Solstice GXP only run 14.1 in MT, I'm not sure it would even be worth it for GM since thats not a big enough difference to justify spending the millions it would cost to change from SS/SC to SS/TC. I wouldnt be surprised if the TC'd engine has even hp numbers and only 20lb/ft more than the SC'd engine on a dyno.

Listerman

i believe a turbo'd vehicle to be more reliable in the long run and way more fun.

Forseti

Sidemount would require getting a lot of electrical stuff out of the way, plus testing for where all that heat would go, and how it would affect other elements...

A lot of testing. A lot of testing means engineers. Means money.

If they can't shoehorn in the standard Ecotec 2.0 Turbo without a lot of rework, I bet it won't happen. Unless the Cobalt gets TOTALLY uncompetitive to the competition, which could happen...

I wonder if it would be cheaper to supercharge the 2.4...

Listerman

Why would Chevy stop thinking about turbo'ing a vehicle because there "may not be enough room?" The car is brand new and no one has done a daily driven turbo'd model except Hahn Racecraft. Of course its going to take money and engineers, they can't just throw a technician in there and start throwing crap around, they will relocate and replace many items in the bay for the shortest routing and perfect fit of a turbo kit.

Wiring didnt stop Brian Cain from shaving his engine bay and completely hiding all sorts of wires, why would it stop Chevy from producing a 2.0l Turbo-Eco?

Mercury

It would fit, I mean they are already in the delta body on the Vauxhall Astra VXR.

this man speaks the truth! when saturn releases it its mine!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

i dunno if ill leave it as a saturn astra im gonna find all the vauxhall badging that i can

rickyw

thats why the aftermarket world is there so they can throw there money into it and then we buy it.

Tomtwtwtw

I saw that, but it's a little lower output from what's in the Pontiac / Saturn. They have it rated at 240 ps (about 237 hp). Pretty potent, though...

Saturns are going to be rebadged Opel's not Vauxhall's. Look up the Opel GT, and Vectra, Same thing as a sky and Aura

yes i forgot its an opel but its an astra! i been waiting for this car for as long as ive herd of it!

saturn some day will be the new cadillac i know i know as funny as that sounds they are redesigning everything to make it look top notch european styled! the Aura is beautiful, sky is beautiful, next is the astra, and mabe the vecta but the astra is the next ion buddy

IMADreamer

You believe wrong. lol There is no proof of any kind a turbo is more reliable then an SC or vice versa. As for more fun that's a person preference. Whatever floats your boat.


Why is it a lot of people here want the turbo engine in the next gen Cobalt? There are no real benefits to it over an SC. The pros and cons of each equal out.

that is true... but due to cfm limits of our supercharger... until they come out with a better unit (i.e. whipple 75ax) those in search of big numbers only have one way to go...

ist GM making the 08 cobalt a turbo???

CobaltSonOfS.A.M.

It my not be called the Astra, they didn't carry over the GT and Vectra names, so why the Astra? But then agan there is the Opel Astra(Germany), Holden Astra(Austrailia), Vauxhall Astra(Great Britan), and Chevy Astra(South America). Who knows?

cvenom2122

DMANIT ASTRA NO MATTER WHAT! lol j/k

CobaltSonOfS.A.M.

And there is a reason it looks all top notch European styled, it's DESIGNED in Europe, Saturn is A rebadged Opel, Bob Lutz said it, it eliminates a whole engineering and design department in GM, and fills in the old Oldsmobile spot, right between Pontiac and Buick. The new GM domestic line-up is: Chevy, entry level; Pontiac, Buick, and GMC are going to be sold as a group at dealerships, Poniac will be the sporty line, Buick will be the luxo line, and GMC will be the luxo truck/SUV line(think Dodge, Chrysler, and Jeep); Saturn will be the Import fighter line(think Lexus/Acura/Infinity); Cadillac is to remain the top luxury line(think BMW/Mercedes).

Keep in mind there is more to it than another Delta platform having a turbo.

Just because it fits the chassis doesn't mean it will fit the different engine compartments.

I am willing to bet that the Cobalt SS dies with a LSJ under the hood.

CobaltSonOfS.A.M.

No way would they have two delta Chevys and not put a turbo in both, example:'08 HHR SS Turbo, why put it in that and not the Cobalt too? And I doubt they would have the HHR SS be more powerful than the Cobalt SS, if anything, the HHR SS will be the same hp or less than the Cobalt SS.
