I am in the process of converting an '87 Vanagon Wolfsburg with a VW
factory approved engine conversion kit from South Africa. I have been
asked by the factory to research the possibility of distributing this
kit in the USA and getting CARB certification. In South Africa, VW had
stopped selling the Wasserboxer for some time and only sold the
conversion through the dealer network. The conversion is very complete.
It comes with a complete 2.0 liter motronic engine, filter box,
supports, hoses, wiring harness, etc. What is impressive is that with
very few exceptions, everything has a VW part number and is genuine.
This kit is available for Vanagons with or without AC and also is built
for Synchros. A 12 month unlimited miles warranty on the engine will be
included.  I will update the forum when I am farther along.
