Why not coat the turbo housing?
I've seen little reflective jackets that go on turbo's... but why not cermaic coat them?

Seems like you'd have to be 
to go without coating on a turbo.. why is it that no one does this? Side effects?

But here’s the really clever bit; Ed had Turbo X thermal barrier coatings applied to the exhaust manifolds and turbo housings, while the intake piping and plenum get a full treatment of Cermakrome—another brand of thermal barrier coating.
The result? A 100-degree F drop under the hood. Not only does the cooler air mean more power, it means less boost required from the turbos and an engine that is less stressed. The turbos also spool up faster by retaining interior heat better and scavenging waste gas more effectively, another important weapon in the war against lag. Greater efficiency with greater reliability; it’s a win-win situation.

I had myne coated when it was rebuilt, along with downpipe and manifold. I think its a good idea for anyone with a turbo'd rotary considering how hot they run to begin with.

From the turbo's I've had in the past. Heat wasn't really a big issue unless I was racing it or under boost alot.
Dont get my wrong, anything will help, but most people dont do back to back races. Most times Ive spent at the track, I had to wait 20 or more Min. between runs. It's cooled off pretty well in those times.
I've ALWAYS used Thermal tape on my down pipes to make sure that heat stays out.
Thats an easy do-it-your-self-in-a-few-min Mod.
