2001 Ford Expedition diesel ??
I bought a 2001 Ford Expedition for my wife with the idea of putting a diesel in it. It will mainly be an around town vehicle so I can't see putting a nice expensive Cummins in it. The conversion with engine, trans, ect... would cost minimum $3000.
I thought a 4 banger Isuzu or Mitsubishi diesel would be better for the budget but ( from my calling around) they are minimum $1,200 for just the engine if you can find one. Cummins 4 cylinder is a no go due to noise and lack of availability. So...... I thought why not a 6.9 IDI turboed? The engines are relatively cheap I just need a turbo on it and an E4OD behind it. I'd run bio in it and do a Hydrogen set up for it. With 3.55 gearing in the rear the trucks got 20-21 mpg mixed driving. I might be able to get it to 23-24 with the hydrogen. Good idea, bad idea, does someone else have a cheap option or a line on an inexpensive Japanese engine? |
A) Inexpensive
B) Good running C) Diesel Choose 2. A crashed F250/F350 donor truck with a 7.3 Powerstroke would be my choice, then you have pretty much all you need from the donor (Transmission is electronic). The turbo'd 7.3 is a lot stronger running mill than the 6.9. Neither are particularly quiet. |
Most of the 'good' diesels are quite a bit heavier and have a lot more torque than the Exp's 1/2-ton front suspension can handle.
That said, my favs are the factory 7.3L turbo IDI (93-94) and the 6BT cummins. Every truck those came in has the appropriate drivetrain to handle it. |

They also did a new body style "light duty" F250 in '97 that I've wondered about using the suspension parts from. Oddball 7 bolt wheels though. Your mileage may vary. I've take a mild dislike to the vagueness of I-beams and given some thought to the newer F150 / Expeditions. The biggest thing haunting me about an Expedition is the engine placement in relation to the cab/hood. You have to be part contortionist to work on it. |
I was thinking I would be better off with a mechanical injection engine that way I could fix it if/when there were problems and I could fine tune the system for bio diesel and hydrogen. But, if the 7.3 is easy to work on, tune, diagnose and can be bought cheaper than a Cummins I could go the 7.3 way.
I guess the 460 gas in the ford and the vp44 on my Cummins put a bad taste in my mouth for electronics. There has already been a 4bt Cummins put into an Expidition without suspension problems. The weight between a 4bt Cummins and a full 6bt is 350 lbs. Heavier springs are gonna be a must though. |

I would probably go with F250/350 superduty axles - cheap, strong and plentiful these days. If you're handy, you could have yourself an affordable 1-ton SUV without much trouble. :choochoo: |
The 2wd Expedition is is coil over shock.
This is going to be my wife's car so I don't need it to be heavy duty. |
