I got it with the rb20det in it

Hi from Australia, I have a 2005 Mazda bravo twin cab Ute 2x4, g6 engine in it is stuffed, I also have a vz holden commodore with v6 and complete running gear. Could any body please help with information on fitting the v6 in the bravo. Any help would be much appreciated. Thanks in advance.
