Hi Matt,

First fix the sensors. It's a Volkswagen.  If it wasn't absolutely
necessary, they didn't install it! The speedo you can live without, but
not the temp guage and the OP light. 2.1s fail spectacularly without oil
pressure. Usually #3 connecting rod big end through the top of the case.

There's not much to tuning one.  Plugs, cap & rotor.  New air cleaner.
Oil and filter.  Use either VW or Mahle filters.  (Available from The
Bus Depot for $6 ea IIRC.) Do NOT use Fram filters. Purolator also makes
an acceptable one. There's a great comparison of oil filters at:

Follow the link to the VW comparison at the top of the page...

Set timing to 5� ATDC for stock or to 5� BTDC for a bit better performance.

All this info is discussed at length in the archives and probably on the
Vanagon.com webpage.
