Cool Cummins 4BT Engine swap?

I wanted too know If anybody out there has done a engine swap with a cummins 3.9L inline 4BT diesel engine!? If so what mods were done to to make it work, & fit into the dakota?

For those who want to know about this engine here are some facts.

Cummins came out with a 3.3L, & 3.9L Inline 4 cylinder diesels both B series motors, & called them the 4BT, & 4BTA. The 4bta is the newer gen motors.
The 3.3L is about 550Ib wet, & had 89hp, & 215Tq.
The 3.9L is about 750Ib wet, & had 130Hp, & 355Tq.
Both engines are cominly found in many step van applications such as frito lay, & bread trucks. The 4BT today is also popular as a conversion engine among many light-duty pickup trucks that were originally equipped with gasoline engines. Many have reported getting as much as 25-35 mpg.
The 4BT engines have the same pistons, connecting rods, valve train components, and injectors as their 6BT counterparts. The 6BT is the cominly found inline 6 cylinder 5.9L & the late 6.7L.

I have a 3.9L V6 Magnum stock rated at 175Hp & 220Tq & getting about 17 mpg.
Making the change to the 3.9L 4BT I would lose 45Hp & gain 135Tq.

A guy with a 4BT ranger ran a 8.27 at the strip. Here is the URL http://www.youtube.com/watch?v=yxnfY...layer_embedded
