HHR LE9 to LE5 swap?
Hello, My mom has a 2011 with the Le9 in it. We replaced the transmission in October now suddenly there's a hole in one of the pistons. It has the flex fuel engine in it but the price difference in the engines is crazy. Plus the fact they we don't even have flex fuel in her area and it has never had flex fuel in it. It has 170k on it and shes in love with it so I decided to replace the engine. The question is, can we put a LE5 in it or do we have to go with the LE9?

Simplest answer would be injectors and computer tune are the only difference between the two. There was a member on here who was featured in a documentary where he took an older 2.2 cobalt, reflashed the ecu and had it running on 100percent ethanol. Imo the flex fuel thing is a gimmick. Only problem you would really encounter is the computer not liking the le5. You would need a flash.

Theoretically. I really am not 100percent sure. The internals and accessories and all other parts of the two engines are the same. I don't know if the stock tune for the LE9 would have an issue with an LE5 installed. Injector switch may not even be necessary. Let's wait for one of the gurus to chime in to be safe.
