Transplanting a 1.9 AHU TDI on a 91 Westfalia automatic

ewB here!! Can the the 1.9 AHU TDI be transplanted to my 91 Westfalia automatic? It was installed before on another westfalia with a mechanical pump, and a 5spd manual.

Sure.  No problem.  I have a '91 with ALH but the AHU would be easier.  Kennedy adapter plate, 83+ diesel vanagon carrier bars, oil pump, oil pan, etc...  Use the TDI starter adapter (westyventures).  You'll want at least the euro 3.73 R+P for the auto trans or better yet the custom 3.3 from Country Homes.  I currently have the 3.73 and the gearing is still too short IMO. 

As an aside...  My long-term plan is to install a Porsche 4hp22hl tiptronic from a 90's 964.  I already have the trans and plan on using the compushift standalone controller.  That's a labor intensive (some frame rail modification for mounting, custom flex plate, starter adapter) and expensive conversion (compushift+trans) but I will end up with the same first three speeds and an additional high gear AND a lockup TC resulting in a loping 2600 rpm @ 75mph with a trans that was made for a stock vehicle pushing 4X the hp/torque than the stock vanagon.
