It would be very cool also if GM were to bring back the stage kits they offered on the cobalts.

I really don't think Turbo 4rs are significantly more fuel efficient than NA V6s. And why compare FI V4s to NA V6s? Why not compare their torque and power to other FI engines? Turbo V6 or Turbo V8? Once you start boosting things it's just a matter of money anyway.
