1) when the fan kick in i am not 100% sure, but when i still had my temp gauge in my car, i think it goes all the way to 100 (when i push it hard) then it drops back down, so i would imagine somewhere between 90-100. as it never goes over 100.
2) although its made in japan, it dosen't necessarily mean they can be better. It really depends how u define better. If you do some research on extractor design, you can find heaps of information - and the factory turbline extractors ARE pretty GOOD! and wht I heard from most people's experience is even with japan extractors, they are most likely to raise the HP by 1 -5 hps, BUT you are more than likely to kill your torque......SO......i wouldn't change it if you still want to keep your torque. In my opinion, a few Hps with the consequences of loosing heaps of torque, I wouldn't do it....well thts just me.
