Assuming the world doesn't end before the Z comes out, I honestly think it's going to come down to what is available. I think both sides are going to have more buyers than cars available. Whoever can build more is who is going to win in sales.
Which alternate universe do you speak of?
I think it will be a legendary engine w/ the closed deck block, like the already-legendary VR38 w/ closed deck block. Throw bunch of boost at it and the B58 will likely be ok. Can't say the same thing for the VR30, I think...
Tuning wise, both will make 500WHP with ease, the benefits of the B58 is the small turbo which spools very quickly, so makes the car darty, but also a bit tricky since the power comes on with the flick of a switch early (compared to the Z which has the similar power delivery slightly later in the RPM band, but still similar to flicking a switch).
Nissan could use the fire under their bums. Competition breeds success for the consumer.
hopefully that translates to a nismo being built sooner than later...
Lego is never smooth - one of the reasons I dislike Lego models (it's a great toy for building stuff and playing, but as display models they look awful). A Lego Z would look almost identical to the above, but without the beak for a nose sticking out and a bigger front air vent.
