<>Question for Brent and others who know about the TIO540.  Bit off topic, but I'm looking at a couple C310s converted by Riley to TIO540-NB.  Appear to be single turbo, no inter-cooler, 8.7:1 pistons, rated at 350 hp (one says derated to 325).  I'd appreciate any info or leads (links, shops, pilots, builders) you could give me on the performance, operating best practices, and maintenance issues with these engines.    >>>

I would talk to Aerostar Aircraft as they have similar configuration engines in the 600.
