You can find on ebay quite often a twin turbo 6A12 engine with AWD tranny from a galant. Sometimes it's the older ones with the engine on the drivers side and sometimes it's got the engine on the passenger side. Stick that in there!!

If you don't feel like making it AWD, then just lock the center diff and leave it fwd.

The 6A12 is a 2.5L V6. Sometimes can also find the 6A11, a 2.0L.

Or drop in an EVOIV+ engine/tranny.

Or, cut the engine mounts off the frame and drop in a DSM 4G63.

Possiblities are limitless.

Make it RWD with a longitudinally mounted 4G63.
