I visited Michael near by and took a look at his TDI conversion.

Something about his special engine mount:

You may know the interfering problem with the Turbo mills and
the Diesel engine mounting. This is on every 4-inline engines
out of Golf/Jetta/Passat/Audi gas or Diesel. The turbo charger
is mounted in the middle of the exhaust manifold, just at that
place where the Vanagon engine mount should be. The
customised support just runs below the turbo and keeps this
space open. Additionally, Michaels engine support does have
a bracket for the Vanagon Turbo Diesel muffler, and all fits
together perfectly.

If you do have the Vanagon Turbo Diesel exhaust manifold, you
don't need the customised engine support. But, if you do have this
bracket, all 4-inlines with turbo will fit without modifications to
the turbo charger and its mountings.
