Jon,
   No numbers for you just concepts.   Most fuel
injection engines run about the same.   It is the Cat
that scrubs out the pollutants.   The nuber of valves
an engine has also helps clean thing up a bit.   New
engines have a new rating of low emission and ultra
low emission largely do to the newer controls.
None of this will change the amount of co2 emission.

Long and short of it is that the larger the engine and
the larger the vehicle the more co2 will be emitted
and this is where I might begin to draw a line on
ethics.   If you drive a bigger vehicle than you need
to do the job than you have crossed the line.   I
really doubt that you will go to hell just make the
earth more like hell.   regards gary

Subject: emissions data

given all this talk about emissions i am interested in
getting some
emissions data.  i have always generally considered
that the new the
engine the better the engines emissions.  hence the
california swap
regulation that you can swap in a new engine but not a
older engine.
so i
would like to find out the emissions of several model
years and makes
of
volkswagens.  i have no idea where to acquire this
data.  i assume the
epa
site might have the data some where or it could be in
an emissions test
manual or book.

i have always figured that engine swapping with NA
approved engines
from
later model cars was a good way to improve my vanagons
emissions.  i
would
like to see how much better my actual emission should
be.

i would like to get data for the following years and
makes of
volkswagens.
thanks for what you can contribute.
