[Vwdiesel] Add just turbo to NA?

[Doyt W. Echelberger]

Has anyone added a turbo to a naturally-aspirated 5 speed 1.6 VW diesel 
from the 80's, without using special TD injectors and the TD injector pump 
that enriches under boost? I call this a partial conversion.

Without a turbo, the car (89 Jetta 5 speed at 104k miles) seems to be 
working pretty hard between 45 and 70.

I am looking for actual experience from people who have done a partial 
conversion (Rabbit or Jetta) and driven it for a few years.

That's the main question. I know how to do the mechanical swap,  but would 
be interested in any unexpected problems you encountered in fitting the TD 
parts to the NA block and exhaust pipe.  But mainly I'm looking for how it 
ran after the conversion....at idle, at slow speeds around town, and at 
highway speeds 45-70 mph. (I would expect it to run about the same at idle 
and around town, and I _hope_ it runs easier on the straight and level 
between 45 mph and 70mph.

I wonder if it might also run a little cooler and easier at highway 
speeds....and maybe get a little better fuel economy?

If some of that isn't the case, I don't think I want to do the 
conversion.  I don't want to burn the valves and pistons in the process. So 
tell me if any of that bad stuff happened to you.

After putting in the time and money to do the conversion, did the car run 
significantly better? I already have the conversion parts sitting on an 85 
Jetta TD that is headed for the scrap yard. All I need to do is pull the 
turbo and the manifolds and swap them onto the 89 na Jetta, along with the 
oil pan and the oil cooler adapter. I could also swap the TD injectors and 
the TD injector pump, but they both have 200k on them and probably need 
rebuilding. I know the TD pump leaks from the TD boost tower...about a drop 
per second.

But if I add the TD injectors and a rebuild TD pump, the cylinder temps and 
exhaust gasses will probably run considerably hotter and I'll run the risk 
of melting a piston or burning a valve....and I can't easily swap in the 
factory TD oil squirters that cool the pistons.

So, I'm looking for some advice from people who have been there and done 
that.  Loren already replied when someone ask the question in October of 
2001, so I know I _can_ do it and it will run. Now I'm interested in HOW 
yours ran and what people learned from having done it.
