swap 6.0 for 7.3

[guy1511]

Hello and thank you for having this forum.

I have an 03 6.0 that has started to have problems. Injectors going out and loosing compression in one cylinder, 30% low. Mechanic is giving me some outrageous prices and suggesting that I just get a new motor. This one only has 100k on it and I have taken care of it since I got it, but the last owner put most of the miles on it so who knows what he did to it.

So for my 2 questions.

1) What can I do, myself to repair my current problems? Any suggestions for where to start a diy repair on this motor. How can I possibly diagnose if this is a head problem or if its something else.

2) due to all the problems that I am learning that the 03 6.0lt has I'm considering finding a 7.3 used and swapping them out and parting out my extra parts. I have a 4x4 6.0 If I find a donor truck with a 7.3 what parts will I be able to keep using in my truck, ie will I have to swap transmissions/transfer case or will my tranny work? Will I need all new everything or will I only need the 7.3 and a new wiring harness?

Would love any other thoughts about this task that i'm about to overtake one way or the other.

do a 12v swap

At a minimum (and I am sure there is much more) You would need a complete doner truck with all of the wiring harnesses, the IDM, the PCM a trans unless its a manual then it might be the same (I dont know).Fuel system tweaks, plus mounts and basic plumbing.

I would personally do a 12V swap also.

Take it to an INTERNATIONAL dealership, have them do the bare minimum to get it back in OK running condition, and SELL it. Then go put the money down on a leftover '09...they'll be making some crazy good deals on them in the next 2 months.

A 7.3 swap wouldnt be that hard in your truck , in 2003 they cam in 7.3 or 6.0 , the mounts are the same transmissions should match in the 6 speed the automatics wont match up , you should find a 7.3 truck get what you need and sell the rest . it shouldnt be that bad .

My buddies 04 6.0 just turned 320,000 miles. The only thing he's ever replaced was his FICM and had the rear end re-built. I'd fix yours and keep it.

I have not tried to see, but with the "New" diesel comming, it only makes sense to think a screaming good deal is out there..
Here's a 2010 I just found, seems like a good deal?

OHIO

well any diesels you find now will have been built before jan 1 . the diesel line has been shut down to retool for 6.7 . first ones are coming to our dealership some time in feb .
i know we really arnt discounting them any more than what fords handing out.
