Hey i have a 2.2 automatic with 150,000 miles want to upgrade engine in the near future; what kind of motor can I put in it and is there anything I can do now to make her run faster or preform better.
Thank you. I appreciate the knowledge.I have an ‘06 LT sedan with the 2.2 auto. My understanding is that there are major differences in the actual wiring harness from the 2.2 to the 2.4, otherwise a 2.4 swap would be great. Very noticeable when comparing the ignition coils on the 2.2 in 05-06 models. Also, no one is willing or able to tune the 05-06 2.2, so again it’s limited as far as making the most out of bolt on items such as a header and larger diameter exhaust, or cold air intake pipe. If you were to be able to tune the computer with the said parts, you’d actually make a decent amount of power increase, 15-25 hp for instance. I’m not really sure what the engine will do if you put intake and exhaust besides be louder. It could help a little bit I’m sure.
Obviously if an engine swap was fairly easy, there would be a lot of people doing them in these cars with the 2.2 engine. I usually get the same response of, “ you should just buy one with the 2.4 in it”. As in I should look for an SS or Sport that’s got the 2.4 engine. I’ve looked and haven’t found any that were great deals or anything considering their condition most of the time. I’d like to find a turbo sedan, but they are not particularly common, and I would suppose most people that own them don’t want to part from them. I have found the 2.4 sedans but not many in good shape for the price they are listed for. I like the sedan over the coupe myself.
I have considered getting a mid length header and having a larger diameter exhaust installed. Maybe some lowering springs and aftermarket wheels. I’m not sure yet though as I may have other plans and end up looking for a Cobalt with the 2.4 and 5 speed. I haven’t had my car for too long. I still need to send it to a paint shop since the paint is looking quite aged.
