Engine swap?
My belovid IDI fel victome to cavitation a bout 7 or so months ago and I have yet to find a doner engine or block. My dads freinds dad has a towing company and thy have a 99 f250 they took off the raod because the body was beat to pieces and said I could have the engine.
I was woundering if any of you have done a swap like this, 94 7.3 IDI to to 99 7.3 PSD Both auto trans. Also what you guys thought of the idea.
I know i need the
Engine trans and dash harness
ECM, IDM, and PCM
Throtle pedal
Intercooler
dash cluster.
What els would i need form the doner truck

its going to be an electrical nightmare, but anything can be done with enough money, i prefer the IDI cause they are better running motors and everything is outside the valve covers.... plus you can run HHO.... hypothetically of course

Remember the 99 was the new body style truck, 1/2 the engine under the dash.
The 99 Stroke was one of the best ones they made in my opinion.
And wiring, you will be doing a bit of wiring.
If it is the difference between not running and a lot of work, if you can have the engine and related parts, I would say the price is right.
Just be prepared for some hair pulling.
It would be a good deal if you could set both trucks side by side while doing the swap.
Label where everything plugged in at, don't forget to code both connectors though.
I said that because my son watched me working on things when he was younger.
One day he took a stereo apart someone gave him, then he came asking for help.
He had taken my wiring number tape and coded every wire he removed, did a great job.
But he forgot to also mark the connector it came out of, so the marking on the wire was not much help.

Given all that it would take to swap this engine into your truck, I would look at a 94-98 12V Cummins instead.

I've looked into cummins swaps I could get a reman 7.3 or have mine bored fore less than the price of the adapter.
It wont be possible for me to have them set them side by side as My trucks in vegas and the doners in california and my truck is the only thing in the family fleet that could move with that much weight on it. I know this wont be easy but baring the iflation stimulus pakage actualy working this is about the only chance I have to get my truck running.
As for the intercooler I belive I saw an article of some one using the 99 inter cooler in a 94.5-97 stroke so I'll have to see if I can find it.
Thanks for all the responses.

Franklin can screw up just about any rebuild usualy take 4 or five motors/pumps or what have you befor you get a good one from them. The service manager at our shop was a mechanic when IH was having problems with them they stopped using remans and would have a machine shop sleve them. Instead of boring all the way threw they had the machine shop leave a 1/8" lip at the bottom of the block and machine an 1/8" off the liner. They said they never had a problem with it.

Maybe take the powerstroke and try to sell it for the cash? The problem with this is if you can't have the trucks side by side, there is a possibility that the swap could nickel and dime you.

The SD charge cooler will work on the earlier trucks, but it depends on what radiator your truck has. And even then, I've heard that you have to cut off and relocate one of the cooler ports. So it is doable.
The cost of swapping a Cummins might pencil out when you consider the issues that the reman 7.3's have had, and the fact that good 7.3 cores are getting hard to come by. But that's just my opinion.
Why not buy a truck with a good 6.9 to swap into yours? With a 6.9, you won't have to worry so much about cavitation issues and you can swap all of your current parts onto it. It would get your truck back on the road, at least until you decide what to do for a permanent fix. Would be a day job instead of a month or more with the PSD.

The powerstroke dosen't have a trans in it. I can work on my truck at work. The problem with buying a truck with a 6.9 is I cant find/aford one locally.
Right now I'm basicly bench racing the idea of the 99 powerstroke and taking every ones opinions into consideration. I"m trying to figure out the economic physability vs. cool factor vs not so cool facto when I need parts.
I also had another thought for a intercooler I've mesured the cooller out of a 466 and it should fit nicely in my bumper would just have to figure out how to make and run ducting to it. We have several of the cooler laying around at work.
