Another plus with the Air Plains conversion is that everything firewall forward is brand new, so all is TBO'd to 2000 hours, and if you worry about Cessna SIDs that's a lot of the work done. There are more of these in UK recently, because there aren't any new Continentals available and it costs near same to zero - time. I've no interest in promoting Air Plains, but they are just really nice people and helped me turn my aircraft into exactly what I wanted. EASA mod is easy.
