N/A and forced induction are two different worlds. Assuming you have an integra LS motor, yours and the gsr produce the same amount of torque at the same time, the gsr (usdm spec) has 170hp compared to your 140hp. Once you consider the drivetrain loss and the chassis weight difference, you're almost at the same point, which would make the race come down to driver skill.
If you were to put the same turbo setup on both of those motors at the same psi of boost, the gsr would have a significant advantage due to the head flow, camshafts, and compression.
