I will be doing the same thing.  As near as I can determine, all you
need to do is replace the water pump and thermostat housing with the
ones from the 1.9, and remove the shorter oil filter nipple from the 1.9
and install it into the 2.1, since you won't be using the 2.1's oil
cooler.  (Use two nuts locked together to remove and install the
nipples.)  Retain the same water plumbing and exhaust system.  Without
running power steering, and in my case A/C, there should be no problem
leaving off the cooler (especially in Alaska!), and you get all that
extra power delivered to the wheels.
