I'm changing the 2.0 in my 06 ss/sc to a sc 2.4 with vvt i know I'll need a wiring harness and Ecu but the only ones I can find is out of an hhr that has the same motor and wasn't for sure if that would work....I would also like to know if my 2.0 trans would bolt up and work on my 2.4 if I'm missing anything that I need to complete this swap please let me know this is my first engine swap like this and need as much help as I can get

 

Honestly, you're better off doing in depth research. A lot of guys here are just going to say you shouldn't or can't. I'm sure it won't be easy but I don't see why it can't be done. Good luck
