It is me whom Gerard send the kit, thaks to you again, Gerard.  It was my first turbo rebuild.
Things to whatch for:
- use correct torque on nut on the shaft (don't remember # but search archives for "kbogach turbo rebuld")
  I got wrong torque from a document from official turbo place - snapped the shaft. I was lucky to have spare turbo from junk yard.
- nut on rear housing are evry hard to get off and everyone I talked to snapped at least one stud.  It it snappes below surface - BIG PITA.
  I don't know how to remove such piece.

Every thing else is more or less straightforward.  But  I did it in basement on desk with big vise.   Gerard, do you have vise in your bathroom? :-)
By the way,  I have perception that there are various models of K26 turbos out there - the kit
I got from Gerard has bigger nut.  I was not a problem as I reused old one.
I sent shaft to Turbo United in NH for balancing but just because I forgot to mark position of the nut and propeller wheel relative to each other and rear wheel (or to the whole
shaft, one can say).

Good luck,
Konstantin
