So the VQ37 wants an aftermarket oil cooler if you're hitting the track/driving aggressively.... and runs from 220-240 degrees from what I've read on many posts on here.
However:
The VR30 looks to run 245-260 degrees (see end of each track session):

The video is in 4k, so I did a few screen shots and zoomed in on the temps... I'm wondering if the new Z will also need an aftermarket oil cooler, or, for whatever reason this higher temp range is fine?
