It can more or less be done yourself. We used to have a good instruction thread on here before Photobucket started charging ransom...
The main gotchas / things to know about:
- the turbo wheels and shaft spin in excess of 100,000 RPM. Balance is critically important. If there is damage to either wheel you'll need to send it to a shop that can properly balance the entire assembly if you want it to have any sort of decent lifespan
- before removing the compressor wheel from its shaft you'll need to mark everything so it can go back with exactly the same orientation. See above for why.
- the compressor housing will come off pretty easily. The exhaust housing will probably put up a fight. Expect to have to use heat and a hammer.
- the K24 wastegate is very difficult to separate from the housing. You'll likely also want to lap the wastegate valve and seat as they probably aren't sealing all that well anymore
