Ceramic Turbines?

[Wizard]

The EVO's I believe had this option at some point. As well as titanium shafts and compressor wheel. The titanium was for light weight and superior strength. The ceramic is not only for lightweight, but the main advantage was the fact that not as much heat would be transfered into the turbo. The heat would stay in the exhaust. And if anyone knows the theory of exhaust velocity and heat transfer (read up on exhaust wrap) you would see the reasoning. But I would personally think the extra cost would not neccesitate the possible power/response gain.

Similar to the EVO 7+ sodium filled exhaust valves.
