i just had an idea. well since gm is dropping the SC cobalt after this year and ss i dont know what itl be called then. but the 2.4 will be the top model for the cobalts right! ok.

now heres what i think maybe if gm wanted to they could slap a supercharger a better one on the 2.4 and sell it. (like they shoulda done insted of a small 2.0 litre). or they could turbo it. but knowing gm they wont turbo it. its not in there tastes. but a supercharged 2.4 from the dealer wouldnt be a bad idea. for the last 2 years for the cobalt maybe what you guys think.

i mean the 2.4 stock whp is what 150. it would be at atleast 210whp with that. and emagine stage kits and upgrades.

2.0 > 2.4 in compression with boost

 

Basically yea. 2.0 built for boost.

 

well like i said they would change things around lower compression. the 2.4 would be a better engine for the application.

ryan.

i think the 2.4 with closely related parts to the 2.0 would stomp on the 2.0 all day. with SC just cuz the engine is bigger overall.

 

There is no replacement for displacement!
And high compression doesnt mean you cant boost. It just means there is no room for error when tuning otherwise.......is that my cyclinder going into orbit?

 

We'll we can't count out supercharger upgrades like the ones GM offered for the 2.4 LD9 and 2.2 L61 in the J-body. Sadly, the probability of GM deciding to go that route again might be too slim to hold your breath over. Sure would be nice though.

 

wow im surprised this hasnt got out of hand yet...

 

maybe gm will make a little supercharger like they did for the 2.4 cavy, now that they dont have a supercharged cobalt

 

maybe we should just wait and see

 

isnt the engine the same as teh one's in the cobalt? couldnt you just use that supercharger?

 

GM is prob just going to focus there attention towards the new camaro, we can only hope they Supercharge or Turbocharge Cobalts for 09 or make it avaliable for 2.4L

 

Myave we should worry about whats in the driveway for now...

 

Don't count on GM to do anything to the 2.4. The sole reason the LSJ is being dropped is because of the new CAFE standards that are going into affect. Those new standards are making it tougher for GM to make the new Camaro and the 2010 rwd Impala. The emissions of the LSJ just won't pass CAFE. If anything, I think GM is going to start exploring more torbo options. Why else would they still be working with the LNF? It's setup uses some of the emissions from the engine to help spool the turbo at lower rpm's so that they can avoid turbo lag. By burning some of the emission a second time they are making the car emit cleaner than normal exhaust.

 

two completely different engines.

 

GM has already stated that the 2.4 is going to be called Cobalt Sport. The reason they are droping the supercharger is because the new federal laws for emissions are increasing and the SS/SC does not meet those standers. A turbo on the other hand gets you better gas mileage over a supercharger. Maybe they will convert the redline and gxp 260hp 2.0 turbo ecotec to a cobalt package later down the road.

yep, the cavy ecotecs have a throtle cable, our throtle is electronic w/ no cables. also the computers use different software which is why if you get the 2.2L cavy supercharger from GMPP the flash wont work on the cobalt 2.2L.

 

^and the 2.4 twin cam was more based off of the 2.3 quad 4. im pretty sure the new 2.4 is more based off of the 2.2 correct?

 

Fyi. There are turbocharged production models of the Pontiac Solstice and the Saturn Sky as we speak. They are gm cars are they not? GM, Buick specifically, was the first ever to use a turbocharged engine in a production model back in 1986. And, because I love history lessons, do you know where the 2.4 engine in the cobalt had its debut? thats right, in the solstice. on gminsidernews.com they have already unveiled plans for the current turbo powerplant from the solstice to be in HHR's by '08 or '09. now, if they are able to continue production of the 2.4 LE5 (emmissions-wise) and they are willing to turbocharge a freakin wagon (no offense to the HHR guys) i think the chances of seeing a turbocharged cobalt in the next 2 or 3 years are lookin good; especially after the LSJ goes out of production. the cobalt has a (short) legacy of getting hand-me-downs from the solstice, but so far that has been a good thing.

 

You seem to really want GM to go big with the 2.4L's man. Simmer down. Go aftermarket and be happy that the 2.4L's are getting the support. They're going to stay naturally aspirated and be the sport models.

 

BINGO

Uh, um, the 2.4 was in the Cobalt for over a year before the Solstice came out...so how is that a hand-me-down????? The turbo from the Solstice is going to the HHR and more than likely to the 2009 Cobalt, when the model will be due for a major refresh anyway. But it's going to be the LNF 2.0 turbo from the GXP/Sky Redline, not a turbo 2.4 version.

 

GM is completely dropping superchargers in the next few years. All non-NA vehicles will have turbos to meet rising fuel economy and emissions standards.

 

not really....2.0's compression might be lowered to run higher boost efficiently but the 2.4's comp. allows it to run lower boost and make the same power

 

the 2.4's were 2 different engines and the ecotec setup is a lot better than the LD9 setup

 

actually, I believe that both the Solstice and the 2.4 Cobalt were released in the same year. Did the Ion get he 2.4 early though? I know it got the LSJ early, and I believe that it was the first car to get the L61, correct me if I am wrong.

 

No, the Solstice was actually a half a model year behind the 2.4 Cobalt IIRC. 2.4 Cobalts were on lots in 05 as 2006 models, Solstices didn't begin showing up until 2006.

 

Not to start a pissing match or anything, but the 2.4 was NOT in the Cobalt before the Solstice. And you are right, the turbo engine is a 2.0, but i do not recall saying it was a 2.4 turbo. All i am saying is that there are boosted engines in the pipeline for the Cobalt down the road.

To the poster that accused me of being "all excited" DAMN STRAIGHT! I think this is an exciting time for GM and for us, their enthusiasts. I am currently working on funding for a hahn turbo kit for my 2.4L. The Cobalt now and in the future have some great platforms to build on.
