I will be at SEMA in a few weeks, I'll post all info as soon as I get it!!

 

We want pictures and lots of info!!!! Thanks man!

 

Depending on how large they go with the injectors, they might have to replace a fuel pump, install a fuel regulator, larger fuel lines, etc. etc. That's why I think $900 is a very good estimate...

 

After upping the boost, the next modification should probably be the fuel system.

 

My dealership dude told me that GM wasnt commin out with a stage3 upgrade, is he right or wrong?

 

You can never tell with dealerships, they are usually the last to know.

 

How do these kits work? If I want my car to be a Stage 3, do I have to also buy Stage 1 and 2?

 

Nobody knows.... despite what they might tell you.

Oh ya I forgot... I found this on another forum
Article on Stage 1 and Stage 2 kits...

 

i almost want to get a 3" pully since i have to get one anyways and its pretty sweet that all you need for stage two is a pully. Giddy UP

 

Stage 2 is an ecu recalibration, and a pulley. Maybe something else I'm missing too.

 

Due to the fact that the injectors are allready pretty big I doubt they will be much bigger. And if they are the stock FP and FPR is more than enough.

 

If what this magazine is saying is true, I cant' wait. Plus that should keep the price of stage 2 down. I think all of you should read this article. It very well could answer all our question with the exception of pricing!

 

Just going to say isn't the only difference between stage 1 and stage 2 a smaller pulley? I don't think it's going to be a $1k upgrade from Stage 1

 

You may be better off just getting the stage 1 kit then using a 2.8" pulley instead of stage 2's 3" pulley(which is actually 79mm, just shy of 3")

 

Actually I think the only desirable item will be the reflash. Once people find out the injector size they will get it at their local parts store, and buy the 3" or 2.8" pulley from SFPHQ.

 

Well I was thinking injectors and reflash since it will be a package and under warrenty.

Pulley well I don't think I will need much warrenty on a chunk of metal

 

ah you crazy SS guys.. just like us a few years back with the SRT... so much speculation, all i can say is that it will probably be good bye warrenty, though i'm sure some dealerships will still honor some aspects of it, but it will be a dealership by dealership thing... good luck guys, I on the other hand am getting stage 2 for my srt tomorrow

 

something occures to me, the changes that these upgrades are pully, injectors, computer reflash. a smaller pully cost the same the stock one does if you put it on at the factory, same for injectors and software. if these upgrades are coverered under warranty then why in the hell didnt the car come stock with them? exact same price to make the car but with more hp. something doesnt add up.

 

sorry to burst your bubble but if 8k rpm is that easy to get then why didnt the car come with it from the factory? do you have any idea how much power we would be making at 8k rpm? it would be at least 300hp. there is a reason the engineers didnt do it from the factory, there is always a reason. usually durability but i know the supercharger has a limited operational range. all kinds of stuff you and i dont know.

 

i heard that gm was releasing the stage kits in japan for the cobalts!

the price is

stage one: $19.99

stage two: $1,000,000

stage three: first born child (or mother-in-law)


lol i love all these rumors about the pricing, keep them coming cause it's entertaining

 

The car didn't come with all those changes stock because you are rught it would have 300hp, and nobody in their target market could afford to buy and/or insure it. It's called tuneablity, and the stock hp #'s are pretty good and under rated to begin with. GM is in business to sell cars and parts if there was more money in toasters thats what they would be selling, and by keeping say stage 1 and 2 under warrenty you now would be smart to go to them for your next hp fix. The factory 2.2Ll supercharger kit still has factory warrenty so i think a pulley would not be to much. Do you really think you need a crank gridle and 6-bolt mains for 200hp? they is so much power potential in this motor it's almost scary. I guarantee that stage 1 and 2 will be under warrenty or whats the point in the factory offering them to anybody but drag racers who's car are not street legal, think about it.

 

^^agreed.

 

So with the Stage II kit, will the recalibration of the ECU only be specific/optimized for the pulley that comes with it? Or will we be able to choose a size to our liking (being resonable of course) without any additional tuning?

 

Im thinking the PCM reprogram with be specific with the pulley and injectors. Also remember that the reprogram (or reflash as some like to call it) will be done at the dealership only (at your cost). The Cobalts use a different program procedure than most of the other vehicles - done through a tech 2, candi module, passthrough cable and the tis200 computer for downloading.

As soon as i can get my hands on one (stage 2) im going to install it and let everyone know the details (since I work at a dealership and will be doing 100% of the work myself.

Stage 2 - when it gets here
Intake - when i find one i like
exhaust - when i find one i like

 

My guess just based on the fact that the owner can install the parts on his/her own and only needs a tech to reflash the pcm would be that it is going to be around ~400 on parts for stage one and ~600 for stage 2 (if it includes all stage one parts) lets say ~160 for labor on the reflash for both stages may give you a good idea of the cost
