I'm finishing the replacement of my '84 1.9 with a 2.1 this weekend,
I'll let you know what I think about the power, but my old engine with
207,000 miles on it is kinda tired, so I think I'll notice quite an
improvement.  You retain the exhaust, water pump and thermostat housing
from the 1.9, and you cannot retain the stock oil cooler in its normal
position because of this.

It is a good swap, Bob Donalds of Boston Engines has done it without any
problems minus the cooler, but my engine came with an external oil
cooler/filter set up, which the PO said it needed to keep the oil light
from flickering.
