hey i have a 08 cobalt sport with the 2.4L NA and automatic...i really have been dying to boost it and dont know how or if its safe to! im new to cobalts so im just asking around! is it best to go with super or turbocharger?? and which one and what all do i need for the coversion??

anything will help thanks!

 

hahn turbo kit brother. i dont know if they make a kit for the 08 yet but if they do thats the best way to go. they offer better tuning and the quality is a lot better.

 

I did a supercharger and I like it, but that is just me.

 

Personally i say dont go with Hahn. There tune is lame and the parts are super cheap. Plastic bosh BOV and Two Ply couplers ha. I have a Hahn kit on my 2.4 and it has been nothing but problems. There fuel management and tune is horrible. I guess its a good kit if you want a easy install and never run over 8lbs of boost. There is a company called Milwaukee Motorwurks that builds a super nice kit. Brian has been in the turbo market longer then anyone i know. http://www.milwaukeemotorwerks.com/ Check out his work. He is currently working on my GT35R set up on my 2.4SS. Better bang for your buck.

 

either is fine

www.zzperformance.com

they sell s/c and turbo kits for our motor. i have a custom turbo setup but i was gonna buy the zzp before i found my current one.

 

I have a supercharged 2.4 and I love it

 

i got an m62 for sale if you end up going sc'd 250 shipped lmk!

 

sc is slow lol

 

But the turbos are the only ones who have blown engines so far :P

 

mines fine... and if u wanna go there.......

theres a bunch of turboed kappas pushing 300+ that are just fine and dandy

doesnt matter wut type of boost u use.. if ur tune sucks boom

 

I don't understand the turbo vs the supercharger thing. I see lots of mouths but no dyno sheets. As soon as my clutch is broken in and my tune is updated I will post a dyno.

 

the kappas have dynos.. i got track numbers.. dynos suck.. lol i even have a vid

 

i'm so glad he said 2008 cobalt sport, i respect that

 

 

thanks everyone for the posts...buuuut i must say something...this whole supercharger turbocharger thing is a lose lose! you will never convince a supercharger guy that turbos are better...supercarger has no boost lag and turbos do but turbos have a lot more top end than superchargers. either way BOOST IS BOOST doesnt matter what u go!

AND YAAAA reppin the 08' cobalt sport!

 

yeah and not a Type S yo!

 

That is primarily because the 08's were designated as "Sports". The 06/07's were all designated as the non-Supercharged SS. Same car, different badges.

As far as the turbo v. supercharger debate. It depends on what you're looking to do. The Supercharger is the safer and more reliable setup, but is limited on output, even with the TVS. The Turbocharger setup is more if you're power hungry (300HP + builds), but are willing to take the risks with reliability.

 

turbo isnt less reliable.. idk where this comes from.. i hear more about those things that hold the pullies on s/cs breaking than turbo related problems..


and on turbo lag.. if u get a properly sized turbo that wont be an issue.. the lag is minimal. ive ran s/c cars and pulled easy on em.

either choice is great. 2.4s are awesome boosted.

 

Turbo 2.4's are awsome I lovee my set up

 

The 'reliability' is more from the extra parts needed in the system (wastegate, BOV, charge piping, oil feed lines) that could possibly go wrong. I hear the SS/TC guys have issues with their charge piping coming apart quite a bit. Also it is much easier to overboost the 2.4 with the turbo if you're not watching what you're doing. The supercharger setups are hard to crack 300 with, so the chance of breaking something on the 2.4 is quite low.

That being said, if I were running the 2.4, I'd definately go turbo out of preference.

 

There's a lot I want to say here, but I don't care that much to type all of it and what not

Good luck!

 

lol usually all that stuff comes with the kits that are out there unless u go custom..

sstc stock piping is crappy plastic sht.. my piping is all aluminum along with beaded edges and is welded in spots so its pretty solid. feed line's stainless and the return is like rubber hosing with a lining. wastegate is solid in a Tial and bov is my only crappy part. i have a ebay bov that i been tryna change for a while

 

on the tc vs. sc debate turbos do have lag no matter what size but the smaller u go the more ur killing urself in the top end a smaller turbo might only be good up to 4 grand but then take a **** after that so whats the point! superchargers have 0 boost lag along with less moving parts but just dont have the higher end on there side...and thats total crap saying that you can only get 300hp out of a supercharger! if you cant get more than that then your doin something SERIOUSLY wrong! if you want off the line power superchargers are impossible to beat but if you want power from a roll turbos are the way to go! love both!! BOOST IS A BEAUTIFUL THING!!!
