Good luck! Have fun and take your time! The worst feeling in the world is knowing that you have to rip it apart because you forgot something.
Trust me, I know...

I forgot to install the M10 bolt that attaches the IM to the IM Mount. Had to pull off the supercharger and alternator to get it on after everything was buttoned up.

CAI and full exhaust, and a little wider tires...thats it
i will do. Im just more curious how much faster it will actually be and how much boost i will be seeing
quck question about the exhaust manifolds....there is basically no difference between the LSJ manifoild and the LAP manifold except the o2 bung....is there?

Check out Gene Culley's build thread for what he had to do to make his SAI work with an LSJ manifold. It just requires a little bit of cutting on the manifold to make everything work. Here's the post that you should check out: https://www.cobaltss.net/forums/show...&postcount=207

Night and day. Your Cobalt will be a completely different animal. Supercharging these engines is like turning it from 2 or 3 all the way up to 11.

Is there an extra O2 bung on the LSJ header or a missing one? If there's an extra, just buy an O2 plug and install some antisieze to it and torque it down. If there's one missing, take it to any muffler shop and they can weld one on for you.

Sounds like you've got a perfect spot to put your Wideband O2 sensor, then. Put your upstream O2 sensor in the header, Wideband O2 in the upstream DP spot, and leave your downstream sensor in its current location.

First, you have to be certain you got an LSJ header, because the size is certainly much different than the LAP. You can normally get the part number off the header.
You can't use a LAP header and an LSJ downpipe. When you get both the header and downpipe off, you'll see the LAP header is slightly longer than the LSJ.
From what I saw....
LAP header is longer with a shorter downpipe.
LSJ header is shorter with a longer downpipe.
One cannot be interchanged with the other, and as I mentioned, the exhaust manifold ports and flow is much larger to allow more flow.
I don't quite understand your other questions.
How fast? That is really not something that can be compared apples to apples. Drivers, tune, elevation all play an important role.
How much boost? Well, it depends on the pulley.
On the 3.0 pulley I boosted 12-13 and on the 2.9 I boost 15-16.
