With or with out the turbo wrap this is dew to the lack of an oil cooler so he may have to ad on an aftermarket oil cooler. I do know there are a few other TT 350Z in the area so I may try to catch up with one of them and try to do a side by side comparison, before and after a heavy run checking under the hood temp EGT temp oil temp cool down time ect. I don’t know what else any recommendations?
