OK i have a 2007 2.2. I wanted to know if the garret turbo would work on my year. Also i wanted to get a 2.4 intake manifold, will the turbo still hook up properly? All i have right now is a cai and some sticky tires for a better launch, i must go faster!!

Garret Turbo will not work with the tune they have.

2.4 manifold, Intake and exhaust are a great start for the 2007 cars.

Try that out and come back for turbo later

All of the parts in Garrett's "GT Tuner" turbo kit will bolt up, but it will leave the exhaust manifold air injection pipe hanging open. Also, since their tuning solution will not work on '07-'08 cars, you will have to find another way to deliver the additional fuel needed.

I just ordered a tuning setup from a company called "Carputing". One of the owners told me that their LS2_Edit product supports the '07-up Cobalts with the E37 control unit. Whether it actually works and how functional it will be, I have yet to find out. I ordered it Thursday (3/6) and it is scheduled to ship out on Monday. If it works out, I'll be sure and let everybody know, since most of the L61 guys are waiting for a tuning solution.

As for using the 2.4 intake manifold on an otherwise-stock 2.2, you'll lose a substantial amount of midrange torque in order to gain a marginal amount of top-end power. In order to take advantage of the larger manifold without forced induction, you'd need more aggressive cams and/or a ported head. As of now, I don't think anyone offers cams that will work with the '07-up 2.2, due to the new intake cam having a reluctor wheel pressed onto the back for the cam sensor. I'm currently trying to investigate whether the actual casting is the same as the early cam. GM literature states that the reluctor is pressed onto the cam, so it is possible that they could have used the same casting. If that were the case, in theory, you could be able to press the reluctor off of the stock intake cam and press it onto an aftermarket cam, provided that you were able to index it properly. All of this is my own speculation at this point as I am still in the process of investigating this.

He never mentioned secondary air injection. Maybe he doesn't have it.

Secondary Air Injection on late production 2006 L61's

You can get bolt ons for now, but a turbo would be a good idea if you "must go faster!!"

u can trubo with a piggyback unit, its not as impossible as some people make it out to be.

ok i just noticed something, i have that secondary air injection with that extra hose, i got rid of the hose when i put in a cai, nothing went to that hole, its just open, is that bad?

You could damage the pump if there is no filter on it.

Fallen33

Yah put a filter on it and your good to go.

JasonLives88

were am i supposed to put the hose coming from the engine, there is no place for it on the CAI

originaladrian

go to advanced auto or pep boys and ask for a breather filter. take this filter (its small) and put it directly on the end of the tube that used to go to SAI. annnnddddd your done, thts it. better safe than sorry. i dont have SAI but i would be interested to find out if you guys throw a code when u pull the fuse for the SAI air pump.

My car has SAI and I'll do to that when I get an intake eventually. I will course inform everyone if it throws a cel.

jperris

I would guess that it would definitely set a P0411, since the ecm looks at the o2 sensor reaction to monitor SAI function.

the 07 lt came from the factory with an 2.4 manifold

exhaust manifold not intake manifold
