5 years is too soon for a totally new next gen Z. They can't really justify a new powertrain just yet, so Direct Injection is definitely the only feasable route for Nissan. It makes sense if they just want to hit the 400hp mark for the Nismo. It would be awesome just for "bragging" rights, but I'll probably wait for the completely redesigned model if/when I decide to get a new one. This thread, like so many others is pure fantasy and wishfull thinking...
