I'm reworking my '84 low-top sort-of-westie 5-sp van's motor.  I got this
van about 3yrs ago with a 92 Jetta/Golf/Rabbit 1.8 liter 8-valve inline four
motor already installed, diesel vanagon-style, by the PO.  I've been really
happy with it, it has performed remarkably for me for appx 45k miles so
far.  I've averaged 23.6 mpg.  When I first got the van, through
unfamiliarity with Vanagon cooling systems, I caused the motor to overheat
(no cooling system 'air-bleed'...duh)  following a coolant flush.  I did a
"quick and dirty" headgasket swap (4hrs, including installing a camshaft)
and headed out for the desert SW..Since then ( almost 3yrs and about 30k
miles ago) I've had no problems until recently, when I lost coolant with a
broken hose.

  This coolant loss and subsequent overheating caused another leak in my
(Q&D) headgasket..Tossed in some Barr's Leak and began gathering parts for
some serious work, long-deferred.

  I found a complete low mileage Jetta (93) ABA 2.0 liter motor for $300,
including all the accessories.  I'll be gaining some power with this larger
bottom end plus having a motor that I, personally, know the condition of
after I get it done.

  So far this swap has been pretty simple.  It's fortunate that many parts
and systems are interchangable between the VW inline motors, and many are
also shared with the original WBX systems in the vanagon.  There are many
many resources out there for parts and tech advice when it comes to the
inline vw motors...but not so much on the swapping of inline gassers into
Vanagons...Not like the Subie Vanagon list..I guess there just isn't much to
it...

  anyhow, I put up a few pics on my Picassa page (below) with some
captions..For those who may be interested in how this "mundane"
non-boutique motor install looks as it goes along.  Should cost me less than
$500,  before I re-sell all the extra parts to get that money back...I am
hoping for 2.5 Subaru-like power with inline VW dependabiltiy, simplicity
and fuel economy..
