   Never ever never ever wrap cast exhaust pieces unless you want to replace 
   them.  I also would think long and hard about the risk to the turbo 
   verses the gain in hp concerning wrapping it also.  I raced a 2.3l ford turbo
   (no flames, it was and is a powerhouse of an engine with a bullet proof 
   bottom end.  It also has not dropped any valves unlike my audis have) 
   from 85 to 88,  I could not tell any improvement or turbo response.  It 
   helped to cook the bearings fairly quickly and sometimes I would notice 
   hairline type cracks on the exhaust outlet of the turbo.  I would try to just
   insulate the air intake from the engine heat and pursue other hop ups.  

How about wrapping the *intake* side of the turbo to insulate it from the
heat of the exhaust system, thus keeping the intake charge cooler and
denser? (That's what I originally meant when I asked about "wrapping" and
insulators...)
