The 2.4L SRT4 engine is related to the older 2.5L engines from Chrysler and is pretty stout. RWD bellhousings are available which would make adaptation slightly easier. The 2.4L shares parts with the 2.0's and 2.4's used in other Chrysler products like the Neon, Stratus and the PT Cruiser as well as the Mitsubishi's that use the 420a (same motor and cylinder head, just reversed flow with the same bolt pattern for the intake and exhaust). So there are different intake options available as well as different exhaust options to choose the config you'd like.
