Wow, what a thread! I too am looking to turbo my Aveo5, a 2008 manual. Have you per chance considered going with a Cruze or Sonic 1.4 turbo engine and transmission? That is my plan, find one at the yard, buy it (six speed, obviously) and fabricate to fit. ECU should just prove to be a swap. There will of course be the typical problems, considering the mass of wires! Imagine the possibilities however!
If anyone here knows that it can't be done with some simple switching around of engine mounts and melding with some wire, let me know! I would rather kill the Sonic/Cruze 1.4L turbo engine swap dream before it becomes some sort of obsession!
