Hello, I have the vehicle listed above RWD that has blown head gaskets and needs a new engine. I found an engine from a 2006 GS that's AWD. Can it be used as a replacement? If so, what will I have to change out?

Sorry but they are not the same design. The top end on the engines is different if they are AWD or RWD. So, to use the AWD engine you would need to remove the top end (intake, heads) and swap them over. If you are going to need to do that you would be farther ahead to just repair the engine you have because you would end up taking both engines apart to the head gaskets and then put it back together.
