Re: 2.4L aftermarket parts
Just a random thought, but while theoretically a lot of stuff will swap over, you're not going to pull much out of the Malibu. There is next to aftermarket for performance mostly because this isn't the performance car.
Intake will throw a CEL on you. That alone isn't going to help. I'm guessing if you try to increase the tube to 3" you might also set off the CEL, but nobody here has tried that (or at least tried and posted).
The Malibu is a little over 3400 lbs ... the Cobalt is a little under 2900 lbs. That's a monumental difference and that alone is also going to severely hurt performance.
Probably the only thing that -might- fit would be the headers/down if you gut a lot of the engine bay to make sure there's room.
Exhaust isn't going to transfer. There is no F/I option for the Malibu. There is no tune for the 2.4 other than one that nobody has tested (or again, tested and posted). I was also looking for the gearing, but I know the Malibu is not geared for performance either and the stock tires are low resistance, so you're going to want to change those.
Most of the time, the Malibu is treated as one of two things: 1) an everyday car (generally people not on this site) -or- 2) a "luxury" oriented (i.e. non-performance) car (as in, sound systems, looks, etc). You're not going to find much in the way of performance for what I'm pretty sure you're looking for.
If you want to try all of this, there's plenty you can -try-.
1. Grab the headers/down from the site, it'll bolt up since it's the same engine, but you'll probably need a good mechanic to ensure it's on perfectly.
2. Get some free flow aftermarket true dual-exhaust and get that on.
3. Put on the CAI and get an OBD-II scanner to just delete that code everytime it comes on.
4. Get a tune from the place that was offering it (I forget the name, google or search on this forum should find it for you) and be the guinea pig for it.
5. Get better tires, something sticky, Michelin Pilot SuperSports if they fit (I forget what sizes they have, but great tires).
6. Fabricate a turbo system for the car and ensure you have a mechanic that knows how to work with turbos.
7. Eliminate your back seats, eliminate your spare tire, get a lot of the systems in front, radio, etc, try to pull down the weight as much as possible.
Then, you -might- have a car that can run quarters in the 13s or 14s (after you've spent well into the five digits), but your warranty (if you have any at this point) is out the window, your transmission will likely be shot after some amount of runs down the strip, and you're going to have a headache when something goes wrong.
I'm not bashing on your idea or on the Malibu. I love mine and most people on this forum love theirs. But, there have been plenty of people that come through thinking they can turn it into something for the dragstrip ... I've not seen a single one succeed.
It's like the saying goes: You can put a tuxedo on a goat ... but, it's still a goat.
