I was going to do a How-To guide for a turbo rebuild, but to save me the trouble this kind gent has made a 2-part video 
A few caveat's to throw in:
-The video features a standard thrust bearing. Mine was a 360 degree thrust bearing, and didn't use the funny spiky-edge metal ring seal thing.
-My 360 thrust screwed down with 3 screws as opposed to being laid together (you can see it on the right compared to the one in the pack on the left)
-The orange seal around the edge of the compressor housing was too big, so I laid it in and cut a section out to make it the right length
-I didnt remove the bottom circlips from the back of each bearing (no need)
-When I reassembled, I re-inserted the turbine/shaft before tightening up the thrust bearing, then fitted the next bearing over the shaft, then laid the compressor backing over that and pressed it in until the "piston ring" seal clipped in. This was to make sure everything was aligned properly and I hadn't tightened the thrust bearing down slightly off-centre.
-Make sure you feel the front and rear oil seals clip into place. They are basically tiny piston rings on the shaft.
