The brake boosters are different:
Base = D7210-1ET1A
Sport/Nismo = D7210-1ET0A

Hoping the OP can solve his problem.

AND this is your PROBLEM! easy fix but that's the source. Since the booster on the sports z pushes more fluid and your z now isn't, that explains the lack of stopping power. Its the same idea behind electricity when you add multiple lightbulbs on one circuit and they get dimmer.

I'm sure somebody would have mentioned it by now.

Z1 says you need a new oil line for the caliper (hardline).

I'll be getting it fixed in the next week or two. I've searched and people that upgraded never changed the booster.

Has to be a air bubble.
