hey guys im about to order a 2.4 SS. i was wondering what gains do you think ill get with just a intake,header,high flow downpipe, and cat back exhaust. i know HP tuners supports our engine..what can I really do with this and will it add any HP? i mite be ordering it very soon...i test drove one the other day and loved it...cant wait...HELP!

 

I say you get a ss/sc spend the extra 2000 and have a cobalt with real power.

 

With HP tuners you can remove alot of the nanny controls in the pcm, you can change shift points and all sorts of fun stuff.. there are a few guys here that can do a custom tune for ya... i went with a westers garage tune for my auto 2.4 and its been great.. i dont know if hp tuners offers more flexibility... anyway with a tune, intake, header, dp, and a cat back you should be looking at some very nice gains....what are you planning to order auto or 5sp?

 

i plan to get auto. i would get a ss/sc but umm i cant afford it. even with my accident insurance will go up. yep cant beat ******** drivin 60+ into you...well i know the guys at Cobalt Addiction...so they will be tuning my car...

 

Your a joke. 215whp is not real power .

anyways with what your wanting to get you can get about 180ish at the wheels. And yes getting a tune will help bring out the most in the car.

 

Congrats, the 2.4 is a great choice - especially if you are in the market for an auto.

I've got a wife who for physical reasons, can't drive a stick - and I refuse to be belittled by the 5spd. folks. I've been around for half a century, and can slap a stick with the best of them, but there are reasons for certain compromises. I used to break 11 sec. in the 1/4 mile in the 60's - before most on this forum were even born - so i've got nothing to prove.

Sorry, few to many brewskies I guess, anyway...

I plan on modding her to the streetable limit, n/a. When a reliable, tested turbo comes out aka. Hahn, I'm down for that too.

Yeah, I've got the Wester's tune too. It works great for the auto - not so great for the 5spd. guys. I think a Vector's tune is best for a 5 spd - possible a dan.spec tune? Yes, hp tuners is available for the do it yourselfer - who wants to learn from their own mistakes - been there, done it before, bought the t-shirt. The best bet IMHO is to get it professionally tuned, then buy hp tuners and start tweaking.

I've got the mods you mention - plus dual e-rams. I think I've got a little over 200 crank hp. In "L" she chirps second. Not bad for a little n/a auto, huh? I'll have it dyno'd shortly and will post the results. Some are hoping for 200whp w/cams. What it does is what it does - who knows?

I'll let you know when I get mine and have her dyno'd!

 

I got a 2.4 SS sedan and I love mine! Great choice! From what I can gather with bolt ons you can expect about 180 at the wheels give or take. With a tune and cams mybe 200 but thats in the works by GTMike right (I hope I got his name right!)

 

I said get a "cobalt with real power" as in the cobalts that are out sstock. not a "car with real power" if i ment that i would have said get a vette

 

all the ss/sc around me are breakin trannys, differentials, and engines. these cars when modded are not good in the cold weather. im not sure if i want to go thru that with my car. i drove the 2.4 and i was very impressed compared to my other cobalt. i think with some decent mods this car has some good potential. i can always supercharge it and it would be a beast. wut does it run stock 1/4 mile? or with those mods i mentioned..what should it run?

 

lots of juicy mods for our cars,just follow the JBP cams thread, Im starting to test them yommorro

 

You might approach 15 flat if you can launch your auto well. With a cam, you'll break into the 14's, driver or not.

 

Man I hear tm everyday *tear* test em already!

 

The guys asking what mods will do to his car, not what car should he get. If you have nothing nice to say about our cars, then kindly stick to your ss/sc section only.

 

haha. im most likely will be ordering the car this week or next week. it takes 6-8 weeks. im stayin black. i passed a 06 2.4 in black and it looked so nice..yet ill have tints on mine just like i did my other cobalt. the rims that come stock are nice. how are the stock tires? when i got my car i didnt have the stock pirelli's i had mich. those were awesome. so im thinin keep it stock for a lil while. then do a intake probably go XTC intake that i was goin to protype on my old car..so ill prototype that on the 2.4. then ill do GMPP Performance Exhaust, GMPP Header, possibly XTC 2.5 downpipe with high flow cat...and you guys said doing the cams will do alot for our cars and then tune. what do u think ill be at with those mods?

 

What are you talking about. Yours has 159whp, 215whp would be a major improvement.

I'd still get the ss/sc, because there are really cheap power mods out there.

There is no reason to buy the 2.4L WITH options. The 2.0L comes with so many standard options that it is worth it, and for about another $1,200 you can make 250whp.

I understand you want an automatic, but if that is the only reason, I would reconsider and get a 2.0LSC

 

does anyone read anymore?? even a little bit?? he very clearly stated that he NEEDS AUTO!! which means no 2.0 for the dummies that don't know that

 

see the only thing from holdin me back is one..so many of my friends cars have been breaking down. do i really want to go through that and not be warrantied through GM? they had alot of problems w/ GM. they put all the cars back to stock and GM refused to work on there cars. so now they are f**ked. im not sure if i want to go through this. 2 blown motors,2-3 broken differentials/tranny's,soo many broken axels...do i really need this? and not be warrantied.

 

By "put them back to stock" I'm guessing they had stuff done to them. That's a risk you take with any car. You'll take it with whatever Cobalt you have - 2.2, 2.4, or 2.0.

I have a 2.0 and have yet to have a single major problem with the engine or tranny. The only people I know of who have had tranny issues have been user error and/or aftermarket parts. It's your money so do what you want with it, but from what I've seen around here most dealers grossly overprice their 2.4 SS's so be sure and research what you're getting and what you want out of the car before you commit to anything.

 

I never said it wasn't an improvement or a difference but 215 its not "real power", real power is 300+ in a fwd car. I'm just tired of seeing the 2.2/2.4 post about power mods over ran by the ss/sc guys saying "why bother get an ss/sc" or "shoulda bought a ss/sc" so don't come in here thinking you guys bought some ****** race car. Anyways end of rant.

back on topic

With the full bolt-ons plus cams and a tune you should see 200 whp. But i also agree that the 2.4's with options are only 1-2 grand or so less then the ss/sc. However if you pick up a base 2.4 with few-no options you can get them for around 17k. Mine was a good 4-5 grand less then any ss/sc's on the lot.

 

I got my 06, 2.4 auto with pioneer sound for $17,500 out the door (including DOC, but less tax) - just to give you a comparison price to see if your dealer is trying to rape you.

 

dont get me wrong i dont need a auto i can drive stick...i just choose to have it cuz i want remote start and as a car audio installer im not bypassin a ****** clutch for a remote start. u need that by me with drivin early in the am. but if i can tune the shift points and such it mite just be worth it. yeah i dont need all the options. plus my dad gets a discount on the cars cuz of his job. i wud get a 2.0 but im not sure if one i can afford due to my accident. insurance will go up. so maybe a 2.4 mite just do the job, for now. until i can afford that z06 or whatever with some crazy whp. but i was impressed with my 2.2 i raced my buddy that had 2.6 pully,downpipe, tune, 60lb injectors,mounts,etc. and my car with just a intake kept up with him up till his top of 2nd(7000rpm). now gettin this bay boy mite just be a good run for the money.

 

i seriously doubt 15 flat in an auto on stock rubbber....nobody has broken into 14's with the 2.4 yet have they? it could happen, i just haven't seen a 14 yet.

 

if you are looking for 300+whp you really shouldn't be looking at fwd...i am not trying to discourage people here, but awd or rwd is much more efficient at that point. 215fwhp is real power on any stock fwd car. its about 65whp more than what the 2.4 should be putting down and that is ALOT! i see people on here saying blah blah blah you will be at 200whp, but i havent seen a single dyno close to 200 at the wheels yet. i could be wrong and i apologize if i am, but seriously now, where are you guys getting this from, i hope you aren't just making random estimates because those can be VERY wrong. if anyone on here has hit 200whp in the 2.4 they should have easily seen 14.8's or lower and i definately havent seen that.

Here's a 2.4l auto that ran 15.3 w/o a header. I think there's a lot of hidden potential there.

I can't wait to run mine. It runs like a bat out of hell compared to stock - especially after I got the Wester's tune. No problem chirping second gear. Before my recent XTC header and b-pipe install, from a dead stop, I was doing 70mph at the end of my favorite interstate on-ramp. This morning I was doing 75-76mph at the same point.

I know it's not that scientific, (I could be getting a better launch cause I'm used to it more now) but I'm happy.

 

I bought my SS/NA for 18 flat. It had only the sunroof option. It is a 5spd. I could not afford the SS/SC. I could barely afford the SS/NA. ( New house and child !!! ) I got mine cuz I like the way it looks. I considered the SC but doubted the reliability and HATE that huge wing, I am 40 years old. Unless you plan to Autocross or drag race I think a safely modded 2.4 can be tons of fun. It is all personal preference. I like sleepers and as much as the SC attracts attention, well so does the NA. I owned a 70 SS chevelle for 14 years and although my cobalt pales in comparison, it does attract the same attention. There is something awesome about getting something you want, dont second guess yourself, follow your heart. I am sure with your friends at CA and some loot you can mod your SS/NA into a little beast.
