just wanted to ask what are engine swap rules in vic? particularly interested if swapping zc 1.6 to a b18 on a dc2. what do i need to do to legally complete engine swap with engine registered to car?

-do i just swap it in and tell vic roads, "hey i got b18 in my dc2."

-do i need it engineered?

- do i even need to tell vic roads that i've changed the engine

-will doing a manual conversion at the same time change any of the above?

thanks
