I spent all afternoon at Mark Drillock's house today.  We ripped
the front suspensions out of 2 vans for a future swap.  He helped
me time my injector pump with his collection of special
(expensive) tools that I need a set of.  I asked him a million
questions about how and where to find a 1.9l diesel to replace my
1.6l.  While laying under my van, sawing off a particularly
poorly engineered muffler bracket, I looked up at the engine to
see a 1.9 staring me in the face!  This after already adjusting
the injector pump to 1.6 specs :(  I already have the engine I
wanted to buy!  No doubt the PO had no clue.

What do I have to do different to adjust the 1.6 injector pump to
deliver the proper amount of fuel for a 1.9?  I understand that
the intake (and maybe exhaust) ports are different for the 1.6
and 1.9.  Is there any way to tell what type of head this is
without removing the manifolds?  The lifters are hydraulic.  Is
there any performance to be gained by using larger diameter
exhaust tubing than the stock setup?  I am about ready for a
complete exhaust system, so I might as well do it right!

Thanks to Mark, again, for helping a newbie!  I'll be back for
the injector pump adjustment as soon as I can figure it out.
