7.3L Navistar Turbo Diesel VS. 7.3L Power Stroke Turbo Diesel

Technology is great when it works, however, I for one do not want to be a guinea pig. I can't afford or justify the expense of a diesel of any type, but I do know that the the tried and true injection pump has served the trucking industry and farmers well for some 40 plus years now. I just don't think the advantage is great enough at this point to justify the expense. This is just my own opinion and someone with a bigger bank account than mine is more than welcome to their own opinion.

I prefer Mechanics over Electronics any day. First of all, Mechanicall problems can be fixed "with a big hammer" but computer problems, while they aren't so easy. Besides, I'm pretty sure that a new cam will increase engine preformance more than a chip.

Yes but what will you do when there is no cam in your motor ?

In reference to the question of wheather it would be possible to replace the IDI engine with a Power Stroke it would be an absolute nightmare! And in reference to comments about new technology vs. old -- the 21st. century is here! Get used to it!

Otto, I didn't mean only replacing the cam, I bet there are aftermarket preformance pieces to replace everything except the engine block. I think aftermarket replacements could bring more power than your average chip up-grade. Does anyone know wat horse power/ torque numbers were released for the 7.3L IDI Turbo Diesel? are they far lower than the PSD?

I wouldn't have an IDI diesel.Too much trouble,also,less powerful and as I understand harder to start when cold.My Stroker'll rock and roll and it should get down and fly when I get my 100 horsepower Superchip.

What will youdo when that HP chip burns up and your stuck with a really heavy trailer that the chip helped you pull? you would probbably loose some HP, and then you wouldn't be able to move the trailer. I will however agree that electronics are nice, but I myself prefer old fashioed mechanics, sure I could polish a gear smooth, but a Ford dealer could cure that problem, I don't know about a chip going bad. Thats just my opinion.

I ment grind the teeth off the gear, highly un-likely, but it could happen(especially in transmission gears).

In all my years (not that many granted) of working on cars and other equipment I've never seen a stripped gear except in one Farmall tractor caused by having two gears engaged at one time which totaly trashed the 3 planetery gears in the torque amplifier

7.3L Navistar Turbo Diesel VS. 7.3L Power Stroke Turbo Diesel

Otto I used that as an EXAMPLE. Meaning that mechanical problems are in my opinnion probbably a lot cheaper to fix than electronic problems. Any (while, almost any) diesel engine should have more than enough torque to break gear teeh, even your average bicycle will strip gears. Say the cam shaft gets jammed(don't ask me how, this again is only an EXAMPLE), something PROBBABLY will go wrong with the timeing chain or timeing gears. Notice I also said in my last post it was HIGLY UNLIKELY that gears would be stripped.

fordiesel69,
I know what you mean about the powerstrokes being expensive to fix. They are also TOTALLY electroninc controlled. Even the throttle pedal is an electrical unit that uses no throttle cable. Kinda wierd. I bought a wrecked 95 a couple months back to do a drivetrain swap with my 86. I might just trade the powerstrike to a buddy of mine for the 7.3 turbo in his 94. Lots easier to work on in MHO. The Powerstrokes are pulling beasts though. Take it easy.

7.3L Navistar Turbo Diesel VS. 7.3L Power Stroke Turbo Diesel

I really would like to compare HP/torque numbers between the two engines, I dought they are very different. Really I'd have to say the most noticable difference is in the injection system. Just in my opinion, the camless diesel doesn't sound like a very good idea. I immagine it will have a lot of trouble at first(like a lot of new deisgns) simply because the speed those valves have to work, that kind of electric lifter sounds expensive. But, the ability to change the timeing easily sounds good. I don't understand why the 6.0L is being made so small

7.3L Navistar Turbo Diesel VS. 7.3L Power Stroke Turbo Diesel

Chebbie seems to like the smaller displacement diesels. Look at thier history. They started out with the 5.7 liter (350 diesel POS) then they had the 6.2 liter (very weak) the 6.5 liter turbo (still weak but getting warmer) and now the 6.0 liter duromax. I haven't heard a whole lot of good about them. The one I drove was very unimpressive. I will stick to my big navistars I guess. If Ford follows through though there is talk of replacing the powerstroke with a 6.? liter version. It maybe designed for F150s and LD F250s though. Maybe they are going to bring back the LD F250s? It will be interesting to see.
