I don't for see displacement getting much if any larger for Nissans V6s as the CAFEs fuel economy standards are only getting stricter. Direct injection would help fuel economy and torque production without increasing displacement Nissan is likely to incorporate their "DIG-T" technology found in the new MR16DDT engine in the Juke. DIG-T stands for Direct Injected Gasoline Turbo-charged, Nissans new MR16DDT has proved that this technology is both fuel efficient, good for making power, and cost efficient. I'd expect to see displacement in the 3.0L-3.8L range with something similar to the DIG-T configuration.
