Cummins TDI, that is. 1994 Dodge Ram 2500, Cummins 5.9, NV4500 5 speed.
The thought of having a computerless engine has been knocking around in my head for a while now. Finally got it.
The first "efficiency" mod I plan to do is a MUCH taller rear end. The NV4500 tranny it has now is more or less a 4 speed with a low gear. I don't ever use the low gear, so if I get a taller rear end, it will essentially give me one more overdrive
As far as the "normal" car buying stuff (lol, on this forum?) it has 263000 miles. When I really got into it cleaning, it looks like it could have less than 150k on it, but it's really dirty. Fortunately, cleaning the seat and carpet were easy (hot water, shop vac). Headliner is coming soon. Oh yeah, and it has no dash. These trucks have a dash made of some really bad dashboard material: it cracks like crazy.
I have not yet gotten a baseline on its FE, I haven't even topped it off yet. Only got it on Wednesday.
As far as the jeep, I know that it doesn't have as much efficiency potential as my jeep It weighs 1800 lbs more, and has 3.4 more liters of displacement. But that is not all that I care about.
Also, I am selling my jeep. I am asking 1900. PM me if you please.
