Hey Guys I currently have a 2.2 non supercharged engine in my 2006 chevy cobalt and I am thinking about doing an engine swap for the 2.4 L engine and I was wondering if anyone knew where I could find a website or around the houston area where I can find this engine for my cobalt.

 

you would spend so much cash for such a little power increase

search around here there are plenty of 2.2's above 260hp, which imo is more then enough for this little car.

 

The L61 is much more moddable than the LE5. Stay with it and use a supercharger or turbo.

 

in for post count.

 

how is it more moddable, they are basically the same engine.

 

Only cause 2.2s use 2.4s intake manifolds throttle bodies and have cams available. However the 2.4s take better to boost!

 

More internals available (Thanks to the Cavalier). The cylinder walls are also stronger since they were not bored out as much as the LE5's. Yes, the rods in the LE5 are better initially, but if you replace the ones in the L61, it'll take boost extremely well.

It is the L61 block that the GM build book uses.

Either way, we can all agree that it isn't worth it to do such a swap when he can just use the engine that is in the car already. The amount of money he'd spend just doing the swap from the L61 to the LE5 would easily exceed what he would spend on building up the L61 and boosting it.

 

True the swap is too pricey.

However the 2.4 has proven to hold more hp than the trans can hold

 

Only way this would make sense is if your 2.2 was completely blown up (rods hanging out the pan, daylight through the block, etc...) and you needed a new motor anyway.

As pointed out ^^^^^, there is a better selection of "go fast" stuff for the 2.2 and for $3k or so you can make 250+ hp out of the 2.2.

 

Subd

 

yeah the 3k would include building up ur engine a bit too. you can go forced induction (FI) for 1.5k if you piece together or 2k tops if you do it on a budget

 

These people speak the truth.

Too expensive and not worth the gain to swap engines. L61 is a good engine, with a ton of room to grow. If your hellbent on having a 2.4, bore out the 2.2 and swap the cylinder head w/ a retune(plus some other stuff that would require an extensive search) to get the VVT action going on.

 

the guy who tunes my car made over 500whp on his 2.2 eco turbo. keep it and boost

 

I see where you all are coming from I just wanted to drop the 2.4 in my car because the engine I have right now already has high mileage on it and I have a friend that I work with who has all the equipment to drop an engine and to put the new one in. But I will go ahead and keep my engine in there then. Thanks guys for the posts!!!

 

The only internals available for a 2.4 are some cams (and last I checked they dont work well with VVT..could be wrong though). and...custom.

I think you can get Valve Springs & Valves.


I havnt really looked around, but dont see much in terms of Pistons, Crankshafts, Sleeves, Etc.

The tranny can be built up, so thats not an issue.

 

you can get alot of internals and whatnot for the 2.2 eco engine because its been around since the 02 cavalier days

 

IMO if you are really bent on replacing the engine I would use the LNF over the LE5. The LNF will have a larger aftermarket if it doesn't already. The LNF is slightly cheaper than the 2.4L however it doesn't include the turbo, IC or any piping. So you'll need to go aftermarket for that.

 

Have there been any successful swaps....

 

It will physically fit, but the real question is whether or not you have the knowledge of automotive electrical systems to make it work.

 

They have trans parts? Where? I we couldn't do much with our trannies like change gear ratio and all that. Is there a parts website? Can we get stronger gears to replace the weak low torque rated gears we have?

 

You can pick up an LE5 for 500-1000 dollars - more on the cheap side if you shop around, and you get a bottom end that handles about 400hp if tuned properly. I'm actually working on a LE5 bottom end/L61 head swap in my cavalier. You get the stronger bottom end and more cam choices with the head.

You cobalt guys have it easier if you go with the LE5 bottom end/L61 head. You don't have to worry about an external crank wheel, just retune and go. You can use the L61 PCM and don't have to worry about the VVT. Get a trifecta tune or tune of your choice - go turbo or s/c and don't forget the thicker head gasket because your static CR will be higher - probably about 11:1.

It's going to be very comprable in price in the end to swap the bottom end vs buiilding the L61 bottom end (if you do it RIGHT - honing/machining, ect), expecially if your power goals are well under 400hp.

Honestly I can't believe more Cobalt guys have not gone with a hybrid LE5/L61.

 

theres 2 people on here that put the lnf in there lsj
