I don't have a problem with a 2.5 turbo 4. The problem I have is that in order to make it powerful enough for the Z name it will come strung out from the factory leaving little to be done with basic bolt-on's. In order to get more power owners will have to change out the turbo and all components. The great thing about turbos is that basic mods will yield good results, but if the engine is already maxed out there won't be much to gain. A 330hp 2.5 won't leave a lot of room on the table. I'd honestly rather than go to something like a 3.0 V6 twin turbo like the old Z32. With todays technology a small V6 twin turbo will not only make good power but it will still get good gas mileage. No need to drop to a 4 cylinder. Not to mention I don't want to have to rev the hell out of the car every time I go up a hill or want to pass someone. Loved my old 06 WRX but it just didn't have that low rpm power. Torque is something the current Z is already missing, going to a turbo 4 won't help matters.
