It'd be nice if Nissan made a nismo appearance package for the sport, or just offered the nismo in a manual.

I'm curious to know if an aftermarket/nismo heat exchanger/radiator would make a noticeable difference on track.

Isn’t the Nismo Z a daily driver that is meant to run on the track “here or there” ? Nissan added an aux heat exchanger as well as an aux radiator to keep things cool. Assuming that an aftermarket radiator is a proven design and has more cores than factory, couldn’t we assume that it would help to keep high temps at bay? Also, a larger more efficient oil cooler would probably do the same I would think. As long as your cooling isn’t so efficient that you’re not getting up to optimal heat range, the only downside side I can think of would be added weight however the increase in performance/ longevity, I would guess, would out weigh (pun intended) the negatives….
That being said, which part is the most important out of the list of possible upgrades? It is for absolutely sure the heat exchanger. This has been proven for years in the Q50 & Q60’s.
If our friend above wants to add all three and then go to the track and then report back his findings, who are we to nay say his track day test and tune process?
remember, the Nismo has been tuned for overboosting and therefore has a bigger expansion tank, having a tune of just 20 more HP and 34+ LBF, the power increase is everywhere on the powerband- therefore more heat. More power = more heat, to make it reliable it's a much needed upgrade. And I personally wouldn't say it's a track "here and there" car, the bite of the brakes is aggressive same with the torque delivery to power out of a corner. Lastly with all Z cars, they've all been tuned in some way shape or form, so an aftermarket intercooler doesn't equate to the Stock being inadequate.
