For you American guys with a slightly better dollar a good place to get a reman is Diesel Auto Services you google that you will find their website they ship engines all over. They specialize in rebuilding IDI engines they seem to be the best at what they do.
As for adding a turbo your probably better off going with a ATS unit which is what Ford used for the factory turbo built in 93-94. I would add a turbo to a IDI if it wasn't so pricey for CND guys like me a turbo kit is a 3000 dollar investment.

It is almost a 3000 dollar investment for us US guys also unless you find a turbo upgrade motor. But if you had one that was set up right, you would say that was the best 3000 dollars you ever spent.
dhag911,
The computer controlled motor is not easy to put in an IDI truck. Wait, the motor is easy to put in, getting it to run is another story. Wiring nightmare is the easiest way to say it. It will cost a small fortune to get all the parts you need unless you buy a wrecked truck that you can take everything off of.
Dash insturments, throttle pedal, wiring harness, computer, rear axle sensor, transmission sensor stuff if it is an automatic, tons of things under the hood just to start.
I considered that route for about 15 minutes when I had a Power Stroke truck setting beside mine. I like a challenge, but I also needed to drive my truck the same year as I started the swap.

The 93-94 factory turbo engine is the same as yours ! The factory turbo system had something built into it to keep it from making too much boost, because ford thought john q public couldnt operate the vehicle with full power unless he broke something in the process. The factory turbo engine, I believe, came with the 2.5 inch exhaust system. You could contact ats and they can send you the upgrade system to make the exhaust system a full 3 inch. And if you go turbo, get gauges !! pyrometer and boost.

All the 93 94 turbo engines I have looked at had the same 2.25" ID exhaust on them the the NA motors had on them.
dhag911, Any 7.3 or 6.9 IDI diesel engine will bolt right up. Everything fits, no fabrication at all. The only three differences were the glow plug system changed in 87,the water seperator moved in 88, and the serpintine belt started in....I can not remember what year. So you can take the above system that is different off your old motor and put it on the new one.
If you got a 93 94 turbo motor, I would contact ATS and get a 3" turbo outlet housing and install a new 3" exhaust all the way back. Any good muffler shop can make you one for a couple hundred dollars.
It took me 14 hours to pull an 86 6.9 old style glow plug system and have a 7.3 turbo with the new style glow plug system in the truck and running. I did have two good mechanics helping me and a well equiped garage to do it in. We also did have a lot of fun while doing it, so it was not 14 hours of straight wrenching.
The three inch exhaust makes the turbo come alive, that wakes the rest of the motor up nicely.

it is already out of the truck and the truck is gone and when they took it out the checked all pressures and wrote them done and will give a 1 year warrenty on the engine. if the problems werent do to neglect of proper maintance.
It had 60 psi of oil and the compression i belive was 390-400 on each cylinder it was very close to all the same on each cylinder

If you want when you get it home you may be able to drain some coolant from the small drain hole just in front of the block heater above the starter. Knowing the level of SCAs was good would give me a warm fuzzy feeling.
Ask them what would constitute "neglect of proper maintenance" and do they want you to keep oil/filter change, fuel filter and coolant change records for the warranty. And what does a 1 year warranty mean, get it on paper/bill of sale signed!!! exactly what it means.
60 psi of oil pressure is good, cylinder pressures... the lowest cylinder should be 75% of the highest....... the manuals say 440 psi is excellent, but 480+ is seen on a new/rebuilt. Yours may be low due to a cold engine compression test.

i never thought of checking the coolant that is a very good point. i would imagine that it was a cold check. the whole warrenty thing is fuel filter, oil oil filter, coolent SCAs, etc.. i dont know all the details since it was my dad doing all the checking and it was his pick up. a friend of ours is a lawyer and he looked at the warrenty stuff and said that it looked good. So hopefully it will last us another 1-1 1/2 years until the 6.0 get a little cheaper.

The serpentine belt came out in 92.
The 91 has the v-belts.
That little change added another 2 to 3 hours swapping all the parts to make a 91 7.3L work with the 94 7.3L factory turbo truck I put the 91 engine in.
The reason was the AC compressor had the serpentine pulleys, and I wanted AC.
Plus all the components on the front changed position. Seems like what is on the left of the engine (belt wise) is on the right (between those years).
AS well, the turbo bolts right up to the 91 engine.
Need to swap a valve cover and some return fuel lines, but all works well.
That swap went well, considering it was raining and I was outside my garage (darned 8 foot ceilings)
