Exclamation 2005 Cobalt LS 2.2 Ecotec Replacement

Long story short I need to put a fresh 2.2 Ecotec in my 05 Cobalt. I'm trying to find out if A) I can simply grab one out of a Pontiac or Saturn and drop it in my Chevy, and B) if I need an '05 or could I pull one out of a newer model. Also, as a curiosity, I'd like to know how difficult it would be to use the motor out of an SS. I'm asking this so I know what kind of variety of makes and models I can look at when it comes to selecting an engine.

You can only swap 05-08 L61 engines into your car that have the same drivetrain. Theoretically you could swap the lnf or the lsj in but it would require thousands of dollars, countless hours of tuning and an unreliable vehicle

Does the L61 have to come from a Chevy or could I use a mint one sitting in an '07 Saturn with 40k (for example).

I don't know how the motor mounts are for the ion, but you should be able to as long as its an l61 and not an lsj

So if I find an L61 in any car the only thing I'll have to worry about when putting it in is engine mounts? thank you for replying and for your patience, I'm just trying to figure out what I should look for and what I can use.

You can only use the l61 from an ion, g5 or cobalt. You can always use your current engine mount and bracket if the other is different. What's wrong with your engine?

I neglected it and ran it low on oil, unfortunately til it started tapping....I changed the oil and it helped for the drive home, then my dad came over to take a look and a listen and it just started getting worse and worse, now its tapping like hell on acceleration and lightly at cruising speeds, in the lower gears it will jerk back and forth on acceleration all while running 25-30 degrees hotter than normal. I've moved it 3 times since the oil change and it feels worse each time.

Probably spun a couple bearings and blew the head gasket. Bearings wouldnt be hard or expensive to replace if you had a few hours. But until you took off the head, you won't know what you're working with. These engines are kind of a pain in the ass to remove just so you know

I put a 2005 cobalt 2.2L into my brothers car and that's a 2004 Cavalier with zero problems everything was exactly the same (engine wise, I know they use hydraulic steering). So a 2004 l61 should work as well, which means a sunfire would be good and I would think a Saturn would be fine as well. If you have to switch mounts then you need to switch mounts
