I did it. Got the kit from PTE. About $100 two years ago and it took a while to get.
A few tips: Get some snapring pliers for the bearing snaprings. I found some cheapies in a $2.00 bin at ACE Hdwe; they worked. I ended up torquing the compressor wheel to 12 in/lbs and used red loctite on the nut; it seemed to have a middle-of-the-road drag at that point that was acceptable. Be prepared to lose a bolt on the turbine housing; they get heat cycled so much they can seize and snap off. Start oiling them ASAP. Getting the compressor housing off the center section is a joy also since some of the bolts are hard to get to and will try your patience. If the turbo can be disassembled sorta easy, you can rebuild it in one day. Clean the center shaft really good but don't use an abrasive, just some good chemicals and a rag. Look for bent or broken fins and scoring on the housings. It's a real close fit in there.
