There are no emission concerns on putting the 1.9l engine in place of the
1.6l because the '82 Vanagon diesel is exempt from emissions (which is how
alot of folks get there conversions through emissions, they just don't tell
the guy that the van isn't a diesel!).  I sell the 1.9l NA diesel engine with
1.6l intake port setup for $1595 brand new.  This is a VW factory engine.
This motor is on sale right now for $300 less than it's normal price.  I have
sold lots of these motors with good results.  Some folks even put the 1.6l
Turbo setup onto the 1.9l NA motor since the 1.9l motor has piston squirters,
and some other items that make the addition of the turbo a non-concern.

Thanks,
