I have heard that you *can* swap an Evo 4G63 into the 4 cylinder 8th gen Galants and use their or some sort of other AWD platform. It has been done somewhere.
Not worth buying the TT V6 from the Galant VR-4 to put it in the car. It won't hold power like the 4G63.
However, you can import all the body panels and what-not to make it a JDM-Spec Galant VR-4
