I am asking because I saw the nose panel you made. My car is not overheating and I have boosted 1.5 bar so far without any problems. Maybe my lower compression is helping me. The most I have hit is 195 and that was 4th gear at 1.5bar.
I installed a Nismo thermostat and I have my fan on 24/7. I have also made a switch for my AC fan up front to aid in cooling when needed. Hope this helps.
