Hm. I didn't know that was the reason (or at least a reason) for the port+DI system.
Notwithstanding this issue, I look forward to a DI'd boosted Z.
The only PITA is that for tuning you have to swap out the fuel pump on DI systems. If its a dual system, like Toyota uses, you can possibly get away with just having the port injectors pick up the slack.
Does Nissan (or Mercedes) have any DI engines on the market yet? That would be a good indicator of what's to come.
