Hi i need to replace my 2AZ-Fe engine from a Toyota Camry '04 Sportivo (5 Speed Man) due to a few problems (Cracked & Warped Head, pistons etc). Toyota have recommended a new engine. Can i replace my 2AZ with a 2GR? Or i am better to stick with the 2AZ replacement? if anyone else has any other ideas, i would interested to hear them as well Your thoughts and comments are welcome.
