Gee, I'm just looking for someone to help tell me if my 91 VW NA  could
readily have a turbo adapted to it, and what the benefits would be.
Noise, power, etc.

  My Dasher is the first TD I ever drove.  It's a bolt on BAE kit.  After I 
got the fuel turned up enough to benefit from the boost we went on a 
trip.  After a couple hills I looked at my wife, with a BIG grin on my face, 
and said  "why did I EVER drive one of these without a turbo!"  Diesels 
are made to be turbocharged.  No funky compensating like on a gas. 
  Sure there are differences in the NA and TD engines but you can 
eek out almost as much from a turboed NA engine as a TD, safely. 
Often the valves don't get replaced with the TD valves, which are 
plasma coated.  The heads rarely get replaced with the "sodium 
injected alloy" TD heads too.  :(  It doesn't seem to be an issue.  
The pistons are different due to notches in them for the oil squirters.  
There's the big difference IMO, the oil squirters.  I've modified a couple 
blocks to do the same as the oil squirters or you can just keep your 
temp limits a couple hunddred degrees F lower.
  Turbos are pretty well set 'em and forget 'em.  Dependable, durable, 
make a nice subdued whistle that sounds cool. :)  Exhaust and engine 
clatter are often a bit quieter than a NA.  Just use good oil and don't 
shut it down directly from higher rpm and load and it'should last for at 
least two engines.  Jake rebuilt his engine and simply swapped the 
turbo back on after the rebuild.
