Spent part of the day getting  the 2.0 liter ABA  94 Jetta  motor I
scored for $100  stripped down.  Preparing for a head swap from my current
1.8 liter inline four (a 92 Golf motor) and install into my  84 vanagon.
Everything in the motor looks really good so far..no surprises other than
how small the inline looks after you strip all the accessories off. It is
16mm taller than the 1.8 liter block...   I posted a couple of pics on my
Picassa.

 Notice the extra compact little built in oil cooler(just above the oil
filter)   that comes on the Jetta motor.  Essentially a water jacket that
fits between the filter and the filter flange.  Could retro onto most VWs I
have ever worked on..

  Ordered new timing belt and tensioner pulley..A new rear main seal,
headgasket and bolts..Gonna have about $250 bucks into this swap and a
couple of days labor.  Not bad for some extra HP (about a 25% increase, I
guess)  So far my only missgivings are the compression ratio is said to go
to 10:1, meaning I'll probably need premium fuel.  However, there is an
inexpensive stand-alone knocksensor available somewhere I am told, should I
find I need one...10:1 is marginal to use regular gas....Maybe if I ever do
another one I will take the pistons and machine out a little to lower the CR
some...but at this cost, I could just let it ping...hee hee.
