His cruising temps are 250+.

Yeah, the 335i is the only other car apart from the 370z and g37 to suffer heating problems, but that car is twin turbocharged, so at least it's somewhat understandable the amount of heat produced.

Did the 350z have an overheating problem? I'm not sure but I never heard of it. Could the reason be the VVEL in our engines? I read that there's a lot of friction going on over there, part of the reason why Nissan developed the diamond-like coating on the VVEL and recommends their ester oil. Maybe the excess friction generates too much heat?
