Turbo Motor Differences "83 Ur-q vs '83 5KT

["Morrell, Mark L" <MorrellML@corning.com>]

If someone on the list knows for sure, what are the differences between the
WX motor in an '83 Ur-q vs an '83 5KT?  I was offered the complete motor out
of an '83 5KT for $100.  My early '83 Ur-q only has 83k miles and the motor
is fine but this is a cheap price to pay for spare parts.  I checked the
casting numbers on the heads and blocks and they do match, even the last
letter.  The head should have solid lifters but I don't know if the valves
are the same size and sodium filled and are the port sizes and cam the same?
The block should have the same pistons but does it have the oil sprayers at
the bottom of the bores?  This is an automatic so is the crankshaft the
same, will it bolt up to a flywheel?  I know the intake manifold is
different but I wouldn't use it anyway.  The fuel distribution head/air flow
unit ends in "J" not "AD" as on the Ur-q.  The waste gate tag is missing on
my car but they look the same.  The exhaust manifold I believe is smaller
inside.  Turbo should be the same, and it is oil cooled. 

I hate to pass this up for the price and will at least get the head but it's
still in the car and I have to pull it myself.  I don't want to waste the
time if the block is not worth it.  Thanks for the help.
