Charlie, the 1.9lTD heads have been machined to accept the 1.6l manifold.  Not
tottally clear on how they do this but I could get some more info for you if
you want.
The $1500 longblock is pretty bare not including the water pump, timing gears,
belt, vaccum pump or even an oil dipstick.  However I do sell this motor with
an installation kit that includes the vacuum pump, oil dipstick and tube, oil
filter flange, timing belt, intermediate shaft pulley, crank gear pulley with
bolt and washer.  The kit adds another $300 to the motor cost so it is $1800.
If you put the 1.6l turbo setup on this motor it should put out some really
nice power (one guy I talked to said 90 hp but I think this a little
optimistic.)
Shipping for this motor depends on where you live.  On the East Coast it would
be around $125-150.  On the west coast it would be way cheaper ($35 if you are
in California).
Let me know if you are interested.
