Don,

That 92 Golf Digifant should have 10:1 CR as well and a knock sensor screwed to the block by the waterhose from head to pump.
You will need a Distributor adapter to use your 1.8
I don't think you'll have to block off the Block oil breather, just be creative with it's routing/hook up.

Here's a great page with the specifics (but some is specific to a CIS fueled car, not digifant (89-92 Jetta/golf)

I have a 1.8 digifant in my 1980 vanagon camper and am currently working towards(slowly) a 2.0 (3A) into a 81 vanagon camper.
So if you have any questions, please feel free to contact me. dan@vwccny.com<mailto:dan@vwccny.com>

Subject: Rolling right along on my 'new' block (inline VW swap into Vanagon)

   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.
