I have also been thinking about this, since I got my X. I have owned a Dodge quad cab dually deisel for many years and am amazed how a 3 ton plus weight truck can get almost 20mpg, all cipped out, with huge intake, 4 inch turbo back exhaust and my lead foot driving. I mean this thing makes huge power and I know the 4 BT also can make huge power. I tow a almost 40 foot toyhauler (trailer with a garage)and it is always overloaded with all my Earthly possesions and a motorcyle and a quad ATV and it still manages 15 mpg.
I will think about doing this, if my engine dies. The 4BT is a great engine and is very durable, but heavy as all get out and will need some deep thinking to make it work. They are very tall engines and that alone makes a very difficult job to fit one in an X.
I really would like to see this happen!
