The water plumbing is easy to acquire, and retrofit.

The benefits of WJ turbos is really too high to ignore Steve.  Since in the 
context of urq's we are speaking of old and stressed (from nonWJ turbos) WX 
motors, the best life you could breath into it and it's now fragile piston 
rings, is to put in a WJ turbo.  The ceramic bearing turbos are really neat 
in terms of performance and longevity, but really in the context of turbo 
heat, the ceramic bearing can just take more of it.  That really doesn't 
change the problem of heat soak across the center bearing housing, nor the 
piston ring temps or center bearing temps during hot run and shutdown.
