I have a 2010 cobalt ls and with the 2.2L suppose to have 155HP I am very much happy with the car in the last year. I would like to keep it N/A but bring the HP to around 180. Any help with the parts needed to accomplish this would be a great help. Thanks -Josh

Full bolt on's will get you from 155 flywheel HP to 180 flywheel HP

You will need:
Intake (Injen is a good choice)
Header/Downpipe (Vibrant is a good choice)
Cat Back Exhaust (Magnaflow is a good choice)

We carry all these and much more on www.TurboTechRacing.com

A custom tune should then push you up to that mark.

Then add a set of Engine/Tranny mounts, to firm everything up (and dress up the engine bay also)

Thanks for your help.

Aaron is correct. Of course its easier to achieve that with LE5 parts so you should consider the LE5 manifold and throttle body. But you're getting into more complex mods if you do so. Shooting high = complicated modding.

I would second this, the 2.4L intake manifold on the 2.2L would be another good choice. Even though we dont carry this, we would still recommend it.

I have heard very bad things. Also don't think you'd even see much for gains.

I'm gonna make life easier on the OP:

Simple:
Injen Intake
Full 2.5" Exhaust
-Vibrant Header/DP (I use)
-Ark DT-S (I use)
Tune

More Complicated:
2.4 Intake Manifold
2.4 Throttle Body
Cams
Head Port
Valve Springs
Etc..

I have seen 2.4's reach 180whp uncorrected (Dynojet for you dyno nutt huggers) with relative ease.. On a 2.2 you'll need to get into the heavy mods for 180+ to be possible. It will become a time and money pit but whatever floats your boat.

I got tired of n/a real quick, but full bolt ons made a noticeable difference

i got intake tb full exhaust and hp dyno tune put down 156 whp your looking at cams springs neutral balance shafts and of course mounts!!!!!

Im sorry for not saying this at first but Im not looking for 180WHP. Im looking for 180hp over all and thank you for all the responses.

My '06 2.2 made 137 Wheel hp with AEM dryflow cold air, 2.4 TB, 2.4 intake manifold, full SS/SC exhaust, and a tune.

I believe yours already has the TB and intake manifold so that would be a waste of time. Cold air and full exhaust with a good HP tuners tune should make the car real fun to drive.

Your LAP already has the 2.4 manifold, just the revised 2008 version from the 2.4 Sport models but you still have the 2.2 TB. And because it also has similar wiring you can bolt in a 2.4 throttle body without a tune. You have to get the 6-pin 2008 version. I have it on my LAP w/o a tune and it helps on the topend along with my SS/TC catback. Hopefully to tune later

yea that was issues with the old design befor they revised it.

but the notice in throttle response is very noticeable it also revs up alot faster because its lighter and in my case smaller

is 180whp possible on the 2.2 without porting the heads? basically with all mods listed above except for the heads?

TurboTechRacing

iTrader: (24)

He is stating in post #1 155 HP stock (flywheel) and referencing 180 HP (Flywheel)

He is looking to gain about 25 HP....

no im asking is it possible to get 180whp on the 2.2 with full bolt ons with cams and valve springs? i have a friend with a 2.2 that we will be doing some stuff to. gonna do full bolt ons with a 2.4 mani and lsj tb. then later do cams and valve springs. just trying to get an idea where we can get him power wise with each of the 2 setups

bolt ons and tune for 50 shot of nitrous. easy 180whp

ATLsilverSS

iTrader: (4)

oh ok. well what are the heads worth then? you're not planning on doing heads are you.....just seems like a lot of money to p&p heads for like 15-20whp.

I believe they do not make cams for the lap. Someone correct me if im wrong so I can get them

i think the zzp le5 cams work cause the lap has the same head as le5
