I decided to upgrade the starter and alternator on my '85 1.9l due to slow
cranking worries.  Pep Boys came through with re-man. items that came with
a "lifetime" warranty.  Starter was a special order (ordered Saturday,
picked it up Tuesday) and the alternator was in stock.  Starter was $160
and alternator $106, (minus core charges).  It does crank better and the
alternator is putting out more voltage.  I measured 14.3 V at the
alternator, 14.1V at the battery.  With high-beams, heater , defroster on,
it dropped to 13.7V at the battery.  I think this is OK.  I am considering
adding an additional wire to get more juice to the starter.  What size
would be worth installing?  (This would parallel the stock wire, which
seems too small.)  The other alternative would be to move the battery to
the back bench seat where it would be 2' from the starter and run one
larger gauge wire directly to the starter and use the existing wire  to
power the fusebox.
As a side note, the new starter came with a replacement bronze bushing.  I
did not use it.  I wasn't sure if I could get the old one out without
dropping it into the bellhousing.  I put it on the shelf for future use
when the motor is out.
