I think, at this point at least, larger turbos are pretty much out of the question. On pump gas, we're going to be limited by the amount of boost we can run. While a larger single or larger dual turbos may be able to provide more airflow, more efficiently, the gains probably wont be enough to offset the inevitable loss in boost response. What's the point of 20 more whp at 7000rpm if you lose 70hp at 3000rpm? But this is all speculation since i have yet to see or drive any turbo upgrades for this car.
cheers,
