i have the 2006 mazda 6 3.0l duritech v6 motor in it (i belive is what they call it) my car has 177k on it the car burns oil badly when warmed up took for a long drive about 30 to 40 miles ive changed the pcv valve, head gasketss, gave it new spark plugs and one coil due to a missfire the problem still persisted so i figured maybe the piston rings were done letting blow by into the combustion chamber also there is another massive oil leak i cant seem to pinpoint due to the mess from the last owner not taking care of it so i wanna pull it and replace it with a 20k ford motor i found from a Ford Fusion because apparently there identical because mazda is with ford right? So i would like to know if this is possible What kind of wireing harness would i have to use will the transmission line up do i need to flash my ecu swap heads or anything crazy to get this engine in and running
