Thanks for that helpful info. I would be using all the intakes and all off the, I guess it would be 2001 3.0L engine, so all of the old 2.5L junk would be just that, junk to me. So I would probably just sell the 2.5 complete in it's running condition as it sits now.
I've also been lurking over at fordcontour.org and seen Terry Haines latest work. They're already making all the mods to put these things into Contours as of now! They can mod the fuel fail to be return style (instead of 2001 returnless), and they have a huge list of other necessary mods to make it all work. I will probably do most of these mods all myself since I have welding skills, equipment, and fab experience, but I may need help from some outfit to get a chip burned (in the case that I would be stuck using my old EEC-IV computer that is in my '95 now), if this is something that is necessary to do to make the swap. I'm still reading to learn more about what all these mods are. I'm also awaiting a letter back from Terry Haines as well to see about getting some pics that he said they have of a Contour with this Taurus 3.0L installed (NON-hybrid, all 3.0L). I really agree with his viewpoint about why use restrictive 2.5 stuff that needs to be extrude honed, etc. on a 3.0L engine, when you can just bolt in a complete engine designed with it's own intake system that was designed to flow the volume of it's 3.0L displacement. Plus the powerband is more in my normal range of driving too. A bonus for me (basically the whole reason I want this setup). I think his logic is the best for my situation and preference. If I go ahead with this swap, I will do a how webpage so others can see better how it's done. Because this route is looking more and more tempting all the time
