So first off I love my g8, almost everything about it. What I don't like is I bought the v6 g8 because that is all I can afford.( I live in Canada and where I live there was only one gt for sale and he was asking 60k....) so what I was daydreaming about is, is it at all possible to swap out my v6 and trams and computer and swap in a 6.0 l or a 6.2 even if I can find all the parts like CPU and trans to match for under 15k or should I keep looking for a gt that is cheaper somewhere?
