Are there and differences between the AU and AU 2 Falcon engines and gearboxes, such as ratios etc., or are they all just in the electronics, and can the engines etc. be swapped?
The AU 2 was mostly a cosmetic makeover of the AU to make it a little more attractive, there were some changes to equipment levels etc., but there were no significant changes to the mainstream six-cylinder and V8. The AU 2 saw the introduction of the dedicated LPG six and a new 200 kW 5.0-litre V8 for the XR8. There’s not reason you couldn’t swap the engines.
