First of all thanks in advance to anyone and everyone who helps me out with this post. I am really interested in the new Z car and it's Infinity knock off the G35 Sports Coupe, however I am wrestling with which direction to go. My hang up really is how much difference there is in the drivetrain of these two vehicles. They both use the same engine, yet there is a 4 ft/lbs of torque in favor of the 350Z. Now I ask you, what could that difference really be or is it just marketing? And finally with the supercharger or twin turbo option being rapidly developed, do you think that a forced induction system designed for the 350z could be used on a G35 coupe since the engine must be so similar?
