4K is high for most engines. Just because the redline has changed, doesn't change the thermal charactoristics of how burning gasoline creates heat.
Consider this, an engine running at 4000 RPM is moving 90MPH down the road. That's a lot of airflow through the engine compartment.
Now, run your engine at 4000 RPM and go 10MPH. Guess what, your engine heats up faster. OMG! Panic ensues, people put up posts about how hot the engine is, and put up youtube videos.
Also, consider that people on here are griping about 220F oil. Seriously? That's nothing to be concerned over. That's just over halfway before oil would have any issues, and over 80F from any potential damage to your bearings.
Go stand in a freezer, then go stand outside. That's an approximation of the difference in temperature that is....and there's still another 100F to go before the oil is in any danger.
Honestly, if Nissan started their oil temp guage at 180F, and had it run up to 350F, and left everything alone, there would be less panic over this - people would be griping about how their oil never gets warm - lol...
