I wish it was a 5.9, but the front end would have needed to be about 9" longer for that. It's actually a Mercedes 5 Banger (it's a tight fit, but it was an easy swap). Strangely enough, It reuses a lot of the factory Dakota parts and a 1st Gen (89-93 Dodge truck) Cummins Turbo Back Exhaust System only needed the downpipe shortened to fit perfectly in my Dakota.
Not only is she Turbo Diesel, but she's also AWD. I installed a Fulltime 4WD/AWD NP203 Transfer Case, did a 3" Suspension Lift and added Coilovers to the Front to help distribute the weight
The noise would definitely go away, after the head and intake launch into space. Your comment had me laughing my butt off.
This thing is going to confuse ALOT of people. My coworker said "It sounds like a big rig, but it's definitely not." I laughed. "Yeah, people are going to hear a diesel but wont be able to find it."
