I rebuilt the Garrett turbo in my SDL. If your car has the Garrett, it isn't any different than the SDL's other than having different turbines. I have no experience with the KKK turbo, from what I've read on them getting parts can be a pain.

The rebuild itself was pretty easy and straight forward. My biggest challenge was getting the bolts out of the exhaust turbine side. One of the bolts was so firmly stuck that we ended up welding an old wrench to the head and using a sledge hammer to get it loose (but it did come loose!).

Be sure to MARK EVERYTHING with a scribe before you take it apart. I made the mistake of not marking the alignment of the center section to the compressor housing on mine. This made it really difficult to realign later. Don't make this mistake.
