Ls4 fit into G6??
I also think that purchasing this car to attempt to modify, especially to the extent that you are dreaming of, is a horrible idea. You'd be better off choosing a different car. My wife has an 08 GT coupe with the 3.5, and I just can not see it as a performance platform whatsoever. Sporty, yes. Anything more, you'd be better off looking for a GTO or another Firebird.
Personally, If I were looking for a "performance" G6, I'd be looking for a 3.9/6M combo.
But isn't this the LS4 section?
