I want this in my jeep! I would really like to know what kind of MPG and HP numbers you get when you are done.

The 1st gen Dodge Cummins and 6.9 IH Fords are what got the American public interested in personal diesel vehicles again after the miserable attempts by GM in the '70s. Those engines only put out 160-ish HP! But Tq. longevity, and MPG were their bragging points. Now Joe Blow has demanded a 400 HP personal diesel truck! Guess where longevity and MPG are now and at what cost!!!

I may turn the pump up a little later on, but I'm going to keep her stock for a while and shoot for mid 20s MPG on 37" tires!
Longevity and MPG are my big intrest in getting a diesel for mine. I just wanted some general numbers when you get them. I'm going to run the NV3500 trans with 3.73 gears and 35's. With that combo I'm hoping for high 20's. This is going to turn out pretty sweet me thinks!

nice motor mounts

Been wondering when I would see someone on here use them finally.

How do you like them so far? I am still trying to perfect them.

Hows your clearance to that passenger side starter? And looks like you may have modified the passenger frame mount?

That might be one of the cleanest drivetrains I have seen in a while! looks good, keep it up!

Jeep 1:Used to have a 93 YJ 2.5l- 3.5" Black Diamond, Chevy TBI 5.7l V8, SM 465 4 speed, 8.8 rear( 4.10, L/S), rhinoline, Mile Marker 9000, NP 231, Had to sell it due to college
Jeep 2: 89/91 YJ, 4BT Cummins, NV4500, NP 231, Old Man Emu 2.5" suspension lift, 1" body lift.....Runs and drives, but very much a project
Interned at Novak Conversions 2 summers ago

Ask me about my 4BT Cummins Motor Mounts!!
