I don't believe the liners/cylinder sleeves are replaceable on this engine. If they are, the labor to perform the job and parts will likely be near the same cost as a new engine.
When the cylinder sleeves are replaced, the pistons and rings are as well. At that point, it would be a good idea to replace the connecting rod bearings, main engine bearings, and basically, overhaul the entire engine.
Let me know if that helps answer your question. If you have others, please let me know.
