try doing that to the supra, 3000gt, dsm, impreza, rx7 and just about every factory turbocharged motor with a NA version. Every car manufact. that has made a turbocharged motor from the factory has developed their motor to withstand the extra power by adding stronger internals.

Its common knowledge that a turbocharged motors yeild the best bang for buck. Why? because of the nature of turbocharging, it leaves alot room for more tuning potential. And to have a factory turbocharged motor that rides on the edge of detonation by maximizing output would be monetary suicide for the car manufacturer. Thats why they leave LOTS of buffer room, which for the aftermarket means tuning potential.
