I was curious if the 3.6 motor in the GTP/GXP is the same motor as in the G8 base model?

I would say no only because one's FWD & one's RWD, but it certainly wouldn't be beyond the realm of GM...

Wikipedia says yes: LY7 motor is the 3.6 in both the G6 and the G8

The motor does not care how its mounted, transverst FWD or longitudinal RWD. The transmission is the key there. Good information to have because this means that you could use engine parts from vehicles other than the G6. Some may require some modification to work but things like heads and intakes should fit with little issue.

I like the G8 but the GT version. The G6 is a better buy if you compare 6cyl. Weight alone is 400lbs different give or take. Never crossed my mind swaping out parts could be an improvement.
