Questionwill an 5.4 liter engine out of a 2005 expedition fit into a 2003 ford expedition the vin# for the 2005 is 1FMPU165X6LA13630 and the vin# for the 2003 is 1FMPU16L03LA98987 and the 2003 has a 5.4 in it now, thank you.
AnswerIke,
From what I can find, it appears that the engine was changed in 2004 and may not work.
You can use any 5.4 from a truck or expedition from 1999 to 2003 (P.I) engines so long as you stay with a 2V engine, or 1997,1998 (non-P.I.) , but they are less power.
Can't quote exactly when, but the Navigator's got the 3V engine sooner than the Expedition, possibly in 01' I think.?
But as far as the Expedition goes, the 2v engine ran from 1997-2003.
2003-2004 5.4 Liter (330 cu in) 16-valve SOHC Triton V-8 gasoline 260 hp (194 kW) 350 lb·ft (475N·m)
2005–2006 5.4 Liter (330 cu in) 24-valve SOHC VCT Triton V-8 gasoline 300 hp (224 kW) 365 lb·ft (495 N·m)
As you can see, the specs are different for those years. I would suspect that you would have to change out some sensors, and the pcm to upgrade. If you can it would be an improvement in power.
I would call some of your local shops, and see if you can find one that does conversions and installs of this nature, and see if it would be cost effective.
