Would probably be a lot of work and expense to switch between diesel and gas(petrol)
but if you swap the motor wont you need to swap harness and computers if its a automatic?Presuming the 2010 is a 1.8l (not a diesel), then the current Oz 1.8l should slot pretty much straight in, as far as I know they are the same Opel engine as is used in the Astra.
