Edit: A third possibility that I never thought of until it was pointed out by a friend of mine was using sleeves to save an engine with a bore damaged beyond what a re-bore could correct. Basically if an engine failed and damaged a bore, sleeves could be used to save an otherwise unusable block.
Some comments on sleeves:
We have the resources to offer any S65 solution, but re-coating the bores can get expensive. Dropping in Mahle pistons is an easy solution as well.
Quick tidbit: Alusil is a brand owned by Kolbenschmidt Pierburg AG. Nikasil is a brand owned by Mahle.
Our client requested sleeves since he will be beating this engine HARD and they offered some extra security. (The engine was in good shape btw) We have had 100% success with CP Pistons and either Darton or LA Sleeve solutions, so its a no brainer.
