My Q has an extra oem "5" = Q455.........wishful to remind me to keep focused on a 5 speed AT conversion..........that will never happen?.............with a few numbers Q45 becomes 444, 454, 455, 55, 554,555, Q300, Q200, QX555
It is actually against EPA rules [Clean Air Act 1990] to install a engine larger or not native to the Q........but as we know only high profile cases get jail time.
They just ignore those 2.4 > 2.0L turbo as a downsize in idle or cruising pollution VOLUME.
But a 7.5L in a car designed for 4.5L might just angier some inspector enough to punish you for consumming too much fuel.
