I got first place in the Martin miniprix in 2001 for my class. This was back when my car was n/a. I was also on street tires, nitto nt450's. I never did an autox where a turbo MR2 ran a better time than me back when my car was n/a. I raced my once when it was turbo, it had really bad tires on it, I never got to race it after that. The turbo is harder to drive, or more challenging I should say, but the turbo is definetly faster, maybe not in the tighter corners, but it exits and accelerates much faster than the n/a, which more then makes up for the fractions of time that the turbo corners slower. Lag ain't a thing with left foot breaking and gas to give load on the motor, then when you exit the turn it's almost like a spring being compressed and then released.
