Hey Welcome to the forums. I think you're the first member to take their 370Z to the track in the US. Congrats.
Your problem is well known by the 370Z Tuners. Mines 370Z in Fuji Racetrack suffered the same problem! Here are more info on the Mine's 370Z
Mine's MotorSports 370Z (fairlady Z) hits Fuji Racetrack 12.08.08

VQ37VHR engine, engine oil temperature to 135 ℃ to take over and fail-safe

Then here's another thread where Namir said that G37 is suffering from the same oil heating issues. Basically once the oil temp goes above 135C, engine cuts down RPMs to protect and prevent any damage to engine.
First potential problem?
Solution? you need to put an oil cooler in so that you can drive the car LONGER without oil temp going up. This doesn't solve the problem but it'll allow you a much longer track time before heating the oil to 135C

Btw, any pictures from the track?
