[Vwdiesel] Need help getting parts from Germany

[James Hansen]

Only trouble with this is you only know what nozzles are installed by taking
them apart and looking at the nozzle part number etched on the body.  The
numbers you see on the outside reflect the part number of the injector body,
not necesarily the nozzle itself.  A rebuilder can put in a range of
different schnozzles.

Any calibration you want to attempt should be done in reference to the
exhaust gas temperature. Use the 1.9 nozzles, leave pump as is, timed to the
performance spec, then increase your fuel in SMALL incrememnts until you
reach the power level you require, without going past the melting point.
Most head/piston alloys let go at 1400 degrees, so you want to use 11-1200
as a start point to not be exceeded.  A good rule of thumb is the smoke
screen method as Dana suggests, but there is nothing like a direct
measurement.

Justaminit.. you're using a 1.6 head on a 1.9 block?  Does that work okay?
