OK... I'll break silence here! :)
I have driven several TDI Vanagons now, both 2WD and Syncro. Both a 15
degrees and 50 degrees. 50 degrees is how they do it in Europe as there is
a real abundance of used parts on the market there. I can honestly say that
the 15 degree setup is better. Two of my friends in Germany asked (begged!)
me to take my VAG-COM over so I could change the idle speed to reduce the
vibrations with their TDI setup. Both has mirror vibration and trim issues
at the 902 RPM stock idle setting. The amount of general noise transferred
to the interior was more on the 50 degree setup as well. Most of the 50
degree TDI owners are suffering clutch slippage with the 215mm clutch and
usually go with some wildly complicated mix and match of TDI/VR6 parts, with
the 15 degree setup you can use the stock 226mm clutch, heavy duty stock
(Sachs) or in my cost a the KEP Stage 1 clutch good for about 230ft.lbs of
torque. It is all hydraulic so clutch feel is the same and there is
definatly NO clutch slippage on my TDI! The other problem that I see with
the 50 degree stuff is it is all used, at least 20 years old and there are
several revisions of it out there so if you start to mix an match you run
into problems. A lot of the parts are no longer available from the dealer
so getting replacements is very hard and expensive. Unlike Europe we don't
have an abundance of Syncro fuel tanks to use the 50 degree setup here. In
fact, the Syncro 50 degree hangers are different so we really don't have a
good setup for the Syncro owners here in North America. For a nice, clean,
reliable conversion that works equally as well with a Syncro or 2WD I would
start with a 15 degree setup as it all new components as it has less
vibrations than the 50 degree setup, you do not have to chop your frame for
gasoline engines, more space on both sides of the motor for simpler intake
and exhaust configurations and the parts are always available.

"Since this is all VW- it makes sense to use it. Only automatics need a
adapter plate."
This is just not true. A diesel bell housing will not
fit in a Syncro. You can replace the fuel tank to make it fit,
but in this case, anything will fit anything. It also will not
allow an inline to be install at any other angle other than 51 deg.,
unlike a KEP set up.
Rob, your clutch pressure plate and fylwheel is smaller
than the stock 2.1L engines. You think this is better?.
I think you better take back the personal preference part?
As for cost it my be cheaper. Definately better.
