I'll follow up on a few points that have been mentioned about the Fox motor.
It is more than the exhaust manifold that makes the low 81hp output of these
motor. The compression ratio is 8.5:1 and the valve sizes are 33mm and
38mm. For comparison the JH motor found in the Cabriolet and Scirocco is
90hp - bigger 40mm intake valves and a little more aggressive initial
timing. In Europe this makes 95hp as they have a dual outlet manifold
attached to it. The Digifant II Jetta / Golf RV engine makes 102hp as it is
10:1 compression ratio and has the 33/40mm valves - the PF motor is 100%
identical with the exception of a dual outlet manifold and a total of 105hp.
Unless you install a Canadian 1.8L Golf III CL head and intake manifold you
will have to cut your frame to make it fit - the early rabbit intake
manifolds require the least amount of cutting but it is a real PITA to make
the intake system for this as it points the throttle valve to the front of
the vehicle.
Another thing is to make sure your hydraulic lifters are in excellent shape
as they tend to fail when laid over at 50 degrees. Vibration can be an
issue at 50 degrees especially if you use the older style Diesel hardware.
If you use a 15 degree mounting system you will not have to cut the frame on
your van. You will not have premature lifter failure. No vibrations and a
simpler exhaust system. The trade off is you have to make a box on your
engine cover to make it fit - no real big deal even if you have a bed back
there as you can get hinges that lift the seat when it is in the bed
position so everything fits.
Just my $0.02 worth!

Has anyone installed a 1990 or newer Fox engine into Vanagon using the
diesel mounts? Did you have to bang the sheet metal to clear the intake? I
have a line on a 90 Fox with new engine and bad tranny for a real good
price...
