Mine is a 94 XLT F-250 4x4 turbo diesel, does that mean it is an IDI and what does that IDI mean ?
does that also mean if it is it wont haul a travel trailer very well ?
how can I give it the power to haul a decent sized trailer ?

IDI simply means Indirect injection. Check the location of your oil dipstick tube as well as the engine badging. Under hood badging will say something about Powerstroke instead of IH.

Also for clarification these rigs were available with the ZF 5 speeds, as well as the C6 and early E4OD.

Powerstroke or not ?
 

Yup, the oil dip stick is on the passenger side and middle of the engine, am I stuck with NO power or could it be a powerstroke, it says nothing about direct injection under the hood . what is the towing capicity of this thing ? it did not even come with an owners manual and I just had a rebuilt transmission put in. it is an automatic. My intent was to convert it to run on WVO, any ideas out there ? I could sell it and try to recover at least $ 7000.00 for it or increase the exhaust to 4inches as recomended and put a K and N air filter on it. please give some more useful feedback. It also says on the doorjam it was made in Nov of 93

when you look at the engine, is there a black box sitting above the turbo that says turbo diesel?

:humm: Had a 7.3 N/A with the ZF5 with a 14; flatbed at a job once, had over 450k miles on it, truck had been rolled once, only maintenance I ever had to do was one starter relay and oil changes. I would routinely load 4-6 tons of grain on that truck and had no qualms about driving it wherever I needed to go. Your never going to win any races but if you want good unloaded mileage and a truck to haul crap around with on the cheap your set.
