The engine, whether it be 2.0, 2.2, or 2.4, is the same block. So, in essence, you should be able to put the SC on no problem. But, I would look into someone reprogramming your comp, and possibly slightly bigger injectors to compensate for the extra air being compressed into your engine. Good Luck!

I don't even know if they've cracked the codes for the 2.2's pcm. Unless you have an 07. They already have them cracked for those I'm sure.

if you have an 05 or an 06 it's not possible... no tuning, so the engine will not run... cannot piggy back it, i know people are going to say that, eventually... and if you put a supercharger on a 2.2 at this point in the game, it won't work either... you will blow your engine up

it's because you can't tune for it... you can't just drop an engine in and get in and drive... there's other modifications that need to be done for it to work properly, and they can't be done...

go to gm and look up there supercharger for the 2.2's, the dealership can reflash the computer. thats the only one right now that is definate. i still hadnt heard back from hahn or other companies yet as to the tunning capabilities. hptuners told me that it will be a while, if at all that they do one for us.

i have a list of part numbers for a performance head, perf cams and adj cam gears, pm me and ill give ya the numbers. they are all gmpp parts. i wzas told that the stock computer can handle those parts or they can reflash the pcm to work.

actually the 2.2s can handle anything(turbo, supercharger, 65 sht of nos, etc) up to 250 hp. then you have to replace pistons, rings, and rods then your good till 400 hp. the problem here is gm got there panties in a bunch for some reason and locked the bitch out so NO ONE can tune the pcm. i emailed gm and they said: "It sounds like you are planning to change the emmisions of the car and in no way can or should you do that." so basically they side stepped me and told me to fk off.
id say go natrally asperated (dont mind my spelling) with gmpp parts. id suggest getting a copy of the 0-1300 hp build book. and youll be happy with the results. gm has a nat. asp. cobalt running salt flats that is amazing from what i hear.

Yes... that is the reason for the production version of our cars. They built it specifically for running down there... they just needed a production version. And I wasn't really looking to supercharge my 2.2 or anything yet because I know it needs to be tuned... I thought pistons and the whole nine would have to be swapped out as well until the above post. At first, I planned on building this car to be a monster... but those dreams faded and now all I want is a pretty quick car I can build up. I like the Cobalt. So, I'm thinkin of trading up pretty soon for either the SS s/c or the RL. Cobalt looks better to me, but RL is cheaper.
