Additional to Per I like to add following:

The old LT series using engines wich have same bold pattern
to the bellhousing like the Audi 5 inline. An engine swap to Vanagon
is possible when using the SA bellhousing.

But if you like to buy that vehicle, don't trash the body, it provides
much more room for a camper conversion. But it has less traction
because of the front engine/ rear drive concept.

I would not recommend the VW 2.8 TDI: Less power, high fuel
consumption. I sent a description of the upgraded 2.8 TDI
to Bjoern, who may translate the article when he's back from
Germany.
