    Can anyone comment on the differences in '06 to '10 Vin Y (LD8) engines from '05

    From what I can tell the injectors and throttle body are definitly different. Does anyone know if the heads and internals are the same? How about sensors? Thanks! Andy

    In 2006, what I know so far:

    Cam Position sensor moved from exhaust cam to intake cam

    Throttle body changed to "throttle by wire"

    Fuel injectors and rail changed

    The 06+ runs 1 crank sensor located near the starter
    the 06+ runs a 58 tooth reluctor ring on the crank

    the oler ones run a 24X
