There are a couple of ways to do it.  I have seen folks swap the entire
cooling system and fuel injection from a 2.1l into the 1.9l Vanagon and
then install everything else from the 2.1l.  This is not necessary, but
if you have a bunch of time on your hands and a complete junk 2.1l then
go for it.

The simpler route that I take is to take the 2.1l block, the 2.1l intake
distributor (black metal piece on top of engine), and the 2.l1 throttle
body.  Now swap everything from the 1.9l over onto this including the
intake runners (water pump, thermostat housing, exhaust system,
distributor).  The only mods you will have to make is to make up a
couple of short hoses for the idle air bypass valve and reroute the
vacuum advance on the distributor.  If you have an earlier 1.9l with the
dual throttle position switches, then you will simply cut the two wires
to go to these switches and splice them to an injector style plug which
you can plug onto the 2.1l single throttle position switch.  Later 1.9ls
are already set up this way.  That is it!  I have done several of these
and they are very easy and work well.  Put a 2.1l into an older
passenger Vanagon with no power steering or A/C for a turbo boost :)
