The list looks something like
 -water cooled turbocharger, take your pick
 -oil supply line(different size turbo flange, 85 ur-q won't work)
 -oil return line(different size turbo flange, 85 ur-q won't work)
 -coolant supply line
 -coolant return line
 -coolant freeze plug with water tap
 -coolant neck at front of head with
     temp sender
     turbo coolant pump temp switches
 -new gasket for coolant neck
 -new upper radiator hose
 -new turbo coolant gaskets/washers(can't remember what it uses)
 -new turbo oil gaskets/washers(can't remember what it uses)
 -misc nuts, wavey washers and studs to attach the lines on the turbo
 -Also need new turbo to manifold nuts along with turbo to downpipe nuts
 -You might also throw in new metal gaskets for both of the above joints.

I haven't worked out exactly what is needed  for plumbing in the auxillary
turbo coolant pump. At this point I am not doing it on my 83 ur-q. Seems
like alot of work. A 1st cut guestimate for doing it with that OEM look,
 -pump
 -upper radiator hose with T to the pump, 5kTQ might work
 -heater pipe with T which runs along the block, 5kTQ won't work,
     too long and different shape
 -temp switches in coolant neck
 -yellow(that's what color mine is)wiring harness which contains
     coolant pump connector
     wires for temp switches
     socket for pump control relay
     pump control relay
 -fab some bracket to mount the pump
 -and other stuff I haven't thought of

For just the turbo plumbing, I got a rough quote of around $600
for all new parts from the dealer. You should be able to pick up
used parts for much less than that.

Good luck.
