Eagle1 summed it up pretty well. Another options is to use an oil cooler.
We could also look into a larger, more effective radiator. But unfortunately both the larger radiator, and the oil cooler, are going to present an even greater cost, most certainly over a grand all in, and there is a fitment challenge. It is already getting snug in there with the FI equipment and certainly in the case of the ATI procharger you are already trimiming part of the fan shroud to leave adequate clearance for the belts. I have not seriously looked into the nismo oil cooler, but with the FI installation, especially the intercooler down low and in front....has anybody put an oil cooler on their car and if so, which one and how did they mount it to get optimal air flow across it?
Horsepower delivers heat, and heat is in general bad news.
Weight of course being the other bugaboo, since it takes more hp to move the weight.

Yeah that is certainly another option though packaging another heat exchanger (oil cooler) up front on the Z is difficult and rather expensive on a TT intercooled Z . This is where the APS air cooled high volume oil pan solves 2 problems in one install,increases engine oil capacity and reduces oil temperature.
