I bet the higher cost of diesel might be offset by the better fuel
efficiency from diesel motors.  Something else to consider is your
climate.  Diesels do have some drawbacks when driven in very cold climates.
  "Equivalent Japanese motors" meaning something small-ish in size and
weight might be a very good alternative to the VW inline four motors, which
seem to be 'crude but effective'when compared.  Sticking with 'all VW' by
using a Rabbit-style motor has a some up-sides..like many interchangable
parts with the WBX and VW mechanics will work on it, maybe even cheerfully
and  effectivly.
  My take, from lurking over on the Subie list, is those motors are great,
once the install is complete and de-bugged.  Their drivers report good
power and reliability, but often mention a slight reduction in gas mileage
from the WBX motor in exchange for that extra power.  Getting them worked
on is sometimes mentioned as 'problematic' also, but the Subie conversion
list is full of great information for doing your own work.
