It's been a while since I read everything but I remember that the MPV one has almost everything you need to be dropped right in. It's the motor that requires the least amount of modification. As far as those modifications go, I can't remember a single thing lol
Edit: Found the post that I was looking for. Here's everything explained as to why the MPV is pretty much a direct drop in.
"You are right about one thing... This engine is a DIRECT drop in.*
I took more pics but my photo bucket was taking forever to load so I will do the rest later.
Looks like a 2.5L timing cover because IT IS.... 2001 COUGAR timing cover.
Engine mount already placed between the heads.
SVT spec oil cooler
2001 Cougar alt bracket
No tabs to cut and there is NO pilot bushing on this engine.
FOR a full 3L there isnt much else you have to do. If the UIM clears the engine bay then an EGR VALVE integration looks to be much easier than the taurus one since its pointing toward the rear of the engine bay. A custom tube would be much easier to fab at this point.
Similarities to the 04-05 taurus... pcv valve is on the same location...
observations... comes with blue injectors returnless style, vacuum system has changed from brittle plastic tubes to rubber vac lines."
