Turbo's are not the remedy to better performance when your putting it on a puny motor. There is not a single 4 banger turbo making the 350hp from the factory that the Nismo is rated. Let alone the 911 GT3RS 4.0 flat 6 that pushed out an astonishing 500hp right out of Stuggart. Yes you can make that power with a turbo 4, but the powerband will not be remotely close to being as usable or enjoyable on a track or in more pedestrian situations.

I personally don't see turbo's as the only saving grace of the auto industry to improve fuel economy, it's just a different way of getting the same results. Power is never free. V6's in passenger cars are already exceeding 30mpg. From an engineering standpoint, it's not all about the motor. The transmission, tire sizing, weight, and aero will all play a critical role. Mark my words, I guarantee there will be 400hp 6 cylinder high performance N/A motors achieving 30+mpg without turbo's.

Concluding points I'm making, I still feel it's very unlikely we will see turbo's in the Z, FRS/BRZ, or the Cayman for a while. The turbo is not the cure for everything, sound engineering is. Nissan has an amazing engineering team and will most likely produce an evolution as opposed to a revolution to the Z. The 370Z is a successful automobile at what it was designed to compete with. I see the Z getting incrementally more expensive, but I don't see it as a problem, it just opens a nice space for true inexpensive performance car in the lineup.
