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.
