[Vwdiesel] 1.6TDI

[Libbybapa at wmconnect.com]

For a while I have been somewhat disappointed that the only TDI models 
available in the U.S. have been the more powerful versions.  Being entirely happy 
with the performance of my n/a 1.6 jetta, I have thought that the 1.6TD in a 
jetta is luxurious regarding power.  I have not driven the TDI, but am sure that 
although it would be fun to drive, if added economy were in the picture I 
would opt for Less power.  I have recently had the thought that it would be 
possible to build a 1.6TDI.  Please correct my thinking if in error.  The early 
TDI's shared the same block as the mechanical 1.9TD AAZ engine.  I know that 1.9TD 
engines have been assembled using the 1.6 head, manifolds, turbo and pump.  
This leads me to belive that a 1.6TD block could be used with the early 1.9 TDI 
head, manifold, pump, controls etc. in order to construct a potentially less 
powerful, but less fuel consumptive 1.6TDI engine.  I imagine some adjustment 
would be needed in the computer controls for the reduced air flowing through 
the engine.  I am also unsure if pump mounting would present any problems.  Any 
thoughts?
