Can anyone give me some advice on how to make my automatic 2005 Chevy Cobalt 2.2 get around 190 hp without getting a turbo or s/c

Thanx

 

Please

 

Bolt ons like intae, exhaust, CAI, Header, Underdrive Pulley will net you if your lucky about 15-20HP

You need to loosen the restrictions in the motor like Ported and Polished heads or head swap, cam helps some what..

I mean right now the 2.2 eco has lots of capability but not without spending some money.

 

How much more power would these things make? Because I was thinking about stage II heads and cams, but unfortunately know little about them.

 

Sell car buy something faster or with more potential. Putting money into your 2.2 will yield mediocre results and you will discover it will basically be a waste of your hard earned money.

 

^ I think you're talking about hondas..this is a cobalt forum.

 

ummm....the cobalt drag car is the 2.2 ecotec and the powerplant is capable of running 250 hp with no internal mods. Just get the GM super when it comes out, it will not void any warentys as long as it is dealer instaled!

 

good advice. or u can wait till the end of the lease or financing or however u're paying and slap a turbo on there and be done with it

 

key word there being WITHOUT i think

 

Go with a Turbo-Zet Heard they are REEL NISE AND POVIDE LOTZ OF POWA

 

then he is being cheap, and u can't have power and be cheap at the same time without compromising reliability :

power, reliable, cheap... chose 2.

 

Turbo Zet


Go there click on the video link of the turbo zet. See how many things you can find wrong.

 

Personally, I am just curious of what the mods will gain. I have done my home work on forced induction, and it is certainly an option, but I want to know what can be done without SC or TC.

So, for my question, does anyone know what kind of gains could be expected from Heads, Cams, and throttle body?

Basically, I want to weigh N/A vs. F/I and see which seems like my preferable option.

The only reason I am looking at N/A options is because I am highly fond of the "sleeper" look, and think it would be awesome to have good power and LOOK like I only have simple mods. So if switching out internals can do that, that would be preferable.

Additionally, if I wanted to go really crazy, I could do the N/A Mods, then add the supercharger later.

Not that I have the money right now, but for this kind of project cost isnt a concern. Especially if I want GOOD work, as well as maintaining the longevity of my car. I am just looking for the bottom line numbers.

Thanks guys!

 

well if you wanted to go n/a you should have got the 2.4 and keep in mind that making good power n/a is gonna be alot more expensive than making good power with a turbo, the 2.2 is a great motor for turbo they even have turbo grind cams for it so i think forced induction will be the way to go for you

 

can't you just get the GM Performance Build boook and look in it. It tells you all kinds of ****. That should give you a good wealth of info too if you don't already know about the motor.

 

B16 and B18 hondas show quite the response to mods and make more power with less displacement, so I dont know what youre trying to say. The n/a ECOTEC has proven otherwise so far.
BTW I hate hondas but that comment was just retarded

 

staying naturally aspirated, who will have to go old school on the engine. like was said, with pistons, rods, cranks, cams valves. you could even stroke the engine. you would probably have to talk to someone who has done it to the ecotech to get good numbers. that type of build of 4 cylinder cars is rare. most people just mod, or forced induction. if you have a local dirt track in your area, go talk to some of those guys. Come classes use 4 bangers in the cars, and the guys will know how to "hot rod" them up

 

WTF are you talking about???? B16 and B18 swaps also cost 3-4K...And you still have a torqueless monster reving to 90353 RPM to make up for it...

what exactly have you done to the Ecotec to base your opinion on this? I find it very hard to believe that an Ecotec of any variant couldn't perform N/A.

 

Okay, first question is, how much do you want to spend? I understand that you are interested in the sleeper look.

You are asking for about 50 more horsepower, which is about %30 more power then the engine already makes. That is a lot to ask for.

The only you are going to achieve it normally aspirated is with nitrous. It won't matter if you do intake, exhaust, head, cams, and pulley. All those thing combined will not get you there, and they will just cost a lot of money.

 

just get a supercharger and that will give you the power you need and still be sleeper

 

most NA cars out there are atleast V6 if not V8 or V10. With the small displacement of the ecotech it will be virtualy imposable to come up with that much gain without FI. There is only so much back presure that you can take off the exhaust before you heart your hp. Your engine is fuel injected so it can only accept so much air. you could probibaly get a nice start buy getting a 4-2-1 header and a custom 2.5 inch flowmaster exhaust and gain maybe 15 if you are lucky. Also the weapon r short ram intake is suposed to give 8-10 hp. A light weight flywheel may free up 5 hp. Then you need to move off to internals like new cam ect. you are going to spend probibaly 5-6k getting 40 more hp when your could spend 2-3k on a turbo or SC.

 

I still disagree, the 2.4L would make a nice NA build

oh and you're not naturally aspirated if you're running nitrous

 

Ok, then what would you call it? To me, anything where the Manifold Air Pressure can not exceed atmospheric is Normally Aspirated. Any MAP greater then atmospheric is Forced Induction.

 

nitrous is in between n/a and forced induction, i wouldnt use it though...

 

Why would that be? I'm serious.
