hopen for some feed back from you guys. i have a 2.4 sport well i debadged it and put the 4 ss emblems that should be on it. Sport??? what is up with that the dealer told me that there was no more ss model and i was trading in my 05 coupe for an ss soo i settled for a sport. i got it in march and they never even told me about the turbo ss i just found out about this site a while ago so i was not educated when i went in.
anyway i have put gmpp intake header and exhaust on my car along with an ark bar.
I want to do more im thinking stage 2 jet chip i need to know from someone who has one if they are any good. OR does anyone have an idea besides nitro and turbo.

please comment

 

Look around there is a lot easy and nice mods out there.

Go in to the how to section to get ideas. ANd look at the featured cars of the past months.

 

just look at member's sigs for mod ideas

I put a solid engine mount from Turbo Tech Racing in my car last night, wow is all i can say
it makes for some intense burnouts and launches

 

Check out www.TurboTechRacing.com

Also look at other brands, if you would like, other than GMPP, Injen intakes have the best power gain...

 

heck yea trust me those guys have awesome parts 4 our cars

 

The 08sport is basically the 05-07 Cobalt SS(2.4).

Just renamed.


I dont know if the turbo kits will work with the 08's. The computers could have been modified, or other things setup differently. Call HAHN and ask.

 

I've heard some bad things about the Jet Chip, but it's your choice and your car. And I went with the Injen CAI first then CA Header then springs. Working on suspension right now.

 

I think most of the bad things you've heard are on the 2.2 Jet Chip Modules. My Jet chip module is working fine.

 

what parts did you have on your car when you installed the jet chip??
did you notice good gains in power the cs rep told me 10h and 12t.

 

i'm suprised the rep didnt tell you more lol they'll do whatever it takes to get you to buy their products...

i think you should do cams, full exhaust, intake, and a killer tune. that'd put a big grin on your face i think

 

was looking at gmpp cam and intake but could not find info on gains. and they are expensive.

 

my jet stage one is working just fine also

 

It was my last "mod", had the I/E already. What it did for the car was get rid of the <4K RPM lag. If your 2.4 is like most autos "getting on it" from a roll the engine seemed to lag until 4K RPM then, like a switch turning on, the engine would scream. With the module it "screams" from "get on it". HP and Tq -- I can't honestly say, I just like the increased get-up-and-go.

 

thanks for the info a think i will get a stage 2 maybe over winter.

 

what part number?

 

Nice. I heard bad things about jet but since on these forums, everyone seems pleased. What about fuel mileage? Did it change for yall?

 

I have the Stage 1 Part # 10708 in my 07 2.4L -- got it through JEGS (JEGS PN 0561-10708). Took 10 days to ship as they do not keep them in stock -- supposedly they are made when ordered. Stage 2 is 10708S - but I haven't tried one of those....yet.

My previous experience with Jet Chips was their prom for the Buick 86-87 GNs and T-Types -- those worked VERY well on those cars!

My fuel milage decreased a small amount -- about 26.9 average in mixed driving. But I also enjoy the part throttle acceleration bursts -- so that might be the reason.

 

Have you considered a custom, dyno tune in lieu of a chip? A good shop (or just someone who knows HPTuners really well) will be able to give you a much more customized level of performance than would a chip.

Outside of that, certainly header and downpipe should be on your list. The exhaust manifold is fairly restrictive as is the factory dp.

Should you decide for a custom tune, make sure you wait until you are done with all of your performance mods to maximize your set up.

If I were you.. and I were planning to stay N/A.. I'd begin researching what your preferences would be and go for full bolt-ons, then the tune, then call it a day.

 

forced indution

 

ftw .

 

GMPP cam?

 

GMPP sells cam blanks, they are not ground.... Comp cams are the only aftermarket ones, that we know of...

 

yea. blanks are inexpensive but you need to know what exactly you want, how much overlap, valve duration, height, etc etc etc... if you know what you're doing, this could benefit you very well.

look if you want to stay NA, do full bolt ons, a couple mild cams and a good tune. maybe even headwork, depends how involved and how much $ you want to put in it.

 

But the primary reason I can think of for staying NA would be A) maintaining warranty, B) not spending a bunch of money or C) ensuring stock reliability.

Major engine work is going to kill all three of those.

 

Very good points.
