Since the 300zx in 1990, you would of thought nissan would of fixed all the cooling issues with all the newer Z generations. Here is a great idea Nissan, make your air dams bigger like all other manufacturers. ?

It goes without saying, therefore I will say it, If the Z heat exchangers support the hp increase some of us are looking for with a tune and downpipes (475-500) without having to buy and install aftermarket ones, that would be great!

I'm dubious about the snout on the Z being large enough to allow effective heat management at increased power levels. You can run upgraded coolers and fans, but damn if that rectangle just seems too small for enough airflow above stock.

This didn’t age too well

Agree, the slits off to the side should employ additional intakes.

In addition to larger HE and oil cooler, another option would be to use a larger capacity oil pan, such the aluminum one dropbear offers for the red sport - assuming no clearance issues with the Z.

It is small. Nearly half of the rectangular opening is actually bumper bar that's not open.
I'm not saying it's a "problem" per se, just be aware that styling may have taken precedence over generous cooling capacity

I'm a little late to this discussion, but was listing to Jason Cammisa on his podcast about the Z, and he was remarking that they absolutely abused the shit out of the Z during filming of the Icons episode (lots of short burst into breaking runs) and it didn't show any signs of overheating.
He also referenced testing he'd done on the Q50 Redsport previously, and apparently they had cooked like 3 cars due to overheating...
I'd say whatever Nissan have done with the Z, it's working.

All of these Z's are being flogged during summer, and I haven't heard one single reviewer mention overheating. Also, the Akebononos, whilst not great, are holding up too.
I remember the first reviews of the 370Z, they were crashing into walls after massive brake fade, and they'd even overheat, despite being NA.
Seems Nissan got some things right this time around........

Yeah, I was and remain shocked at the 370's overheating issues. It's not an "all the time" problem but for a modern free-breathing engine like the 3.7 it's rather confusing. I'm glad that nobody has yet identified such an issue with the new Z's setup, that's very encouraging.

In addition to their heat exchanger, AMS is also protyping better intercoolers top side

Hopefully the Nismo comes with more than a catback, aero, upgraded intercooler, oil cooler, transmission cooler and interior
