Can you put 5.9 CumminsDiesel in a Grand Wagoneer?
I am looking at buying an 84+ Jeep Grand Wagoneer and into it I would like to put a 5.9L Cummins Turbo-diesel from an 89+ Dodge D250/350 4X4. What could really be better than putting the best engine in the world into the world's greatest 4X4! This would give you all the advantages of the great Jeep vehicle, manuverability, 4WD system, etc. with the benifit of being able to get 25-30 MPG vs: 10-12 and still tow any trailer you wanted unlike with the 258 I-6.
I have reasoned that the the engine bay should be long enough being as AMC did put their 258 I-6 in there and it is the same displacement as the 5.9 V-8. Weight will not be more than a few hundred pounds different if that. I know that it would have to be the non-intercooled model as there wouldn't be room for it between the grill and a/c cond. or rad and the plumbing for that would be difficult as well. For power, the 89 non-intercooled 5.9 made about 140hp which, if I remember is about what AMC quoted for the 360 V8 only the 5.9D makes approx 400ft.lbs @ 1600RPM, which is more than the 360 by a fair bit. Now Chrysler hooked this engine to a TF727,, same transmission and usually used about 2.73 - 3.08 so the road speed rpm will be about the same as when it was in a D250 4X4.
If I wanted a Diesel powered Suburban or Excursion, I would have one of those huge overgrown behemoths. What I really want the Jeep. So it looks like it is up to me to build it. I have been involved in other engine swaps before, but they were of the order of an engine that the manufacturer had somewhat designed as in a bigger disp and/or more modern engine/drivetrain. (With one exception, that was putting a 302 and AOD in a Volvo Coupe that formerly had a 2.8V-6 ;-) It killed Mustang 5.0's ... hehe). If anyone has made one or has any suggestions for how, better engine idea, etc, I would love to hear from you.
