Stock Eurovan 2.5 compression?

Right, obviously with increased stroke the rods and pistons need to be
compensated for.  It would be like putting big bore pistons in the stock
bore, obviously the bore will have to be compensated for.  Typically, a
shorter rod will make up the difference nicely.

All the VW 2.0 motors (from the factory anyway) used a 92.8mm crank, the
Eurovan crank is 95.5mm and uses a taller deck to make up the difference, so
I've yet to find factory parts that work perfectly for the I5 short deck
95.5mm application.  I do have a source for 92.8mm cranks, but it uses a much
larger diesel rod jornal.
