I imagine that swap would be pretty interesting, provided you dont mind looking around for a couple parts aside from your 4g motor setup.
There are a couple ways to do this, but this one seems easiest to me:
You'll need a 'W' or 'G' VIN Mitsubishi Mighty Max block (dependent on having a 6 bolt or 7 bolt motor), which allows a bolt up installation of a Starion/Conquest 5 speed transmission, and sets you up for a rear drive setup. The mighty max block is a 2.4 liter tall deck design, but your 2.0 4g head should work just fine. This setup has a longer stroke than the 2.0, and if memory serves, uses the same rod length due to the taller deck.
IMHO, that would be a pretty wicked swap, and would be great if you already have a 4g setup laying around the house.
