RE: Seized 2.1L
Jim, first get it into a shop that can diagnose the full problem, someone
like Schaffner in Lynnwood (one I'm familiar with and trust) or several
other good shops in the Seattle area.  Are you sure the engine is actually
seized or is there a possibility that there is some other problem that is
giving the same symptoms?
I replaced a 1.9L in an '85 about five years ago, long block from NW
Connecting Rod was about $2,600 at that time with a 12 months/12,000 mile
warranty.  Double that amount for labor and the other parts that should be
replaced at the same time.
