I think that my be in part due to the fact that
most of us that own the VW water-cooled inline
fours don't have enough negative issues to talk
about?
Usually you don't think about an engine if it
gives you no trouble, so without the problems
common to the WBX, there is'nt much to report .
A broke timing belt, a bad spark plug wire, do
not make for sensational headlines as head leaks
on the highway.
Yet I don't assume most Vanagon owner's want a
engine conversion as I did when I converted my
'82 Diesel in 1995. For me it was an easy
choice- the 82 Vanagon Diesel engine compartment
was burned to a crisp.
Some things that you can do for better MPG at
top cruising speed is switch to the air-cooled
Vanagon transmission which is the same length as
the Diesel 4-speed.
This one still has the Diesel trans yet still
gets over 20 mpg.
If you want more torque and hp, you can use the 2
liter block and Digifant intake manifold.
That is. putting the 1.8 liter head on the 2
liter block.
The 2 liter engine block is nearly 2 inches
taller, so you have to clearance the left
firewall extra.
To get the full potential from the 2 liter, the 2
liter exhaust should be used as well as the
Motronic system. It's more involved, but has
advantages.
The Diesel engine platform has the dual
versatility that the other conversions don't
have, that is , inline-four Diesel or gas , using
most of the same hardware.
It is a stand-alone conversion that looks like
what VW should have done from the beginning.
Just what was done in South Africa until they
ceased production in 2002, and with larger
engine size options, such as five cylnder inline.
