and yeah i gotta call total BS on the 50,000 mile clutch thing too.. i bought my car with 9k on it, learned how to drive it (granted i had driven manual transmissions on pretty much everything else but a car at that point), and fully bolted and tuned my car while beating the **** out of it on a semi-regular basis. and im at 54,000 with no sign of a bad clutch.

 

As long as you can drive the stick the clutch should last the life of the car (according to GM..lol?)

anywhooo thats cool that you got it tuned, I've wanted mine tuned for a while, but at $300 the benefits of an N/A tune dont seem to justify $300 lololol.

a guy I worked with had a 2007 Cobalt Automatic sport, stock for stock that thing was SIGNIFICANTLY more sluggish/slow then my 5spd 2.4(this was whne I was still stock to).

The new civic Si's arent that bad, I've taken one or two, and the late 90's mustangs are the most fun

Glad you're enjoying your car though , sure its not an LSJ/LNF but you know what the 2.4Cobalt is still a fantastic car none the less, the LE5 is an awesome engine, its obviously slower then its boosted variants, but its still quite a quick car and will still out run most other cars in its class

 

Automatic is WAY slower

Also see if you can find someone local with HP tuners.

Ive taken all V6 mustangs except the new 3.7L cant wait till the S/C goes on

 

Yes I agree my 07 ssna i had just before i got this car seems like it was about as fast as i am currently to be totally honest.... i wish i hadnt of totaled that one and done my mods to that one..... would have been a hell of an NA car....

 

OH MAN..... I just found my old cobalt for sale on craigslist..... I miss that thing so much..... it was such a nicer car than my new one 2007 Chevy Cobalt SS

 

I learned to drive on mine by myself. Bought the car brand new. Had like 9 miles on it I think? Took it off the lot not knowing how to drive it aside from a quick 5 minute tutorial from the salesman. Clutch lasted till about 68,000 miles when the TVS when on. GMPP clutch has been fantastic.

 

Do you have any videos of what your car sounds like??

 

ya it sounds like

"wwwwwaaahhhhhhhhhhhh..........bbbwwaaahhhhhhhh... .vvvrrrooooommmmmmmmmmmmmmmmmmmmmm"

 

just go on youtube theres videos

 

I love these two, the orange has the exhaust done while the blue just has an intake
Cobalt SS/NA 2.4L Flopro V-Force K&N Intake - YouTube

Cobalt Sport Dyno 2.4L K&N - YouTube

 

I don't like the orange one at all

 

agreed

 

the 2.4s seem slightly underrated just not as much as the LSJ's

A full bolt on and tuned auto 2.4 should hang with an SI.
The blue one was dunkinnuts on here. One of the highest dynoing near stock 2.4's. Also a n 08 which for some reason seem to be slightly stronger power wise than the 06-07's though they dont have the stronger rotating assembly.


Im glad to hear the tune worked out nicely. Ive been needing to get tuned for a long while. Im betting a large part of what your feeling is probably torque management being lessened if not turned off completely in the trifecta tune as well as the shifts being cleaned up.

 

i didn't read the whole thread, but a few things from the first few pages...

your car should run very high 14's, i went 14.9 on a K&N SRI, and a Megan cat back.

Stock clutch junk? i've got 148K miles on my car, stock clutch, adn it has around 60 passes at the track along with being driven like a rental. Clutch is great if you know how to drive.

and OP i ran an 08 TC a few years ago, he was my sisters boyfriend. he missed second and third at the track and still beat me 15.6 to 15.65. it was funny watching him pass me twice. passed me in 2nd then missed third and just scrubbed me out at the stripe.

good luck with your build. makes me wanna tune my N/A

 

Its crazy how some honda civics can be like 300HP N/A with a 2.0L engine and yet a cobalt witha modern 2.4L struggles to break 200HP on a good N/A build... wtf is with that?

 

LOL i have a 2.2 and will be tuned in spring.what u just said would never come out of my mouth bc it isnt possible

IBL

 

You only push maybe maybe 172hp lol if that, maybe that's why

 

Theres no fully built crazy 2.4 ecotecs to my knowledge.... and a 300whp honda that na took a **** ton of cash to pull off and its not all that reliable and often tuned within an inch of its life.

 

true that

but whomever i quoted was saying that about stock 2.2's which is rediculous lol

 

um what?


anyways, all things aside I love my cobalt, the 2.4 is a fantastic motor and I'm sure is capable of quite a bit if given the right mods...

but N/A builds just pale in comparison to boost.... you could sink thousands into N/a.. full exhaust/intake/Portpolish/valves/tune etc etc... or for around $1500 slap an M62 on there and be making even more HP then all that off the bat, theres just no getting around the cost efficiency of a superchager (or turbo if you know what you're doing) and an Le5 with a supercharger is something else..

a guy in our local club has a G5Gt with a supercharger stage2 and that car seriously hauls ass.

The only thing I like about N/A builds is.. well theres just something about how a well build N/A car feels when ya stomp on it

 

Ok so im just wondering here.... how safe is slapping a zzp supercharger kit on an le5? I mean im assuming that all of these motors are the same block and that the majority of the displacement difference is in the bore.... am I right? So im just worried about making too much hp for the cylinder walls to hold.... am I crazy or is there some truth to this? And what kind of hp could I make with the zzp kit with a tune not too aggressive? And one last thing.... does s/c increase fuel economy or is it more tc that increases economy?

 

agreed..

but the shitty part is you gotta ask how many retunes most of these s/c'd 2.2's have gone though. there always seems to be some code popping up on them and its **** like that that really sucks!

thats most of the reason why i stayed n/a. i couldve went s/c'd but tuning seems to be a neverending issue and hptuners (which seems to be the best option for tuning) is something i wouldnt trust many people to do from my area. i also like my MPG considering this is my college commuter car, so for what it is n/a seemed to fit the bill perfectly

 

Well dont quote me on this or flame me if I'm wrong but A.F.A.I.K most supercharged 2.4's usually hit 240-250ish WHP, the G5 I was talking about is on a stage two and he says hes sitting on clost to 290.. I CANT CONFIRM THIS NOR AM I SAYING ITS TRUE but the car sure pushes like its making close to that, so I dunno.

The engine can handle boost just fine, its stock clutches that **** the bed when you add boost, and if you're Automatic you should 100% add a transmission cooler.

turbo is the ultimate way to go though, wasn't "Zdeuce24" or whatever making well over 300ish HP with his 2.4 turbo?, thats the serious way to boost, if you've got the cash.

But yeah a 200HP+ 2.4 N/A build would be so much fun, and probably a hell of a lot more reliable.

 

yeah if i had the money i would go supercharge because its cheap and so long as you don't go too crazy by dropping pulley sizes your good. stage 1-2 would be max i'd go without rebuilding the engine. and if your auto it'll hold over 300hp very easily. n/a build like others said too much money. just basic bolt ons and tune if ya want a little fun without spending too much. thats the route i went and i'm happy with the performance of the car.

 

When I got tuned for the first time, it put a smile on my face
Most people feel the same way
