Lama engine conversion.
 

Reading that the Indians have modified their Lamas and for that matter some of their Alouette 3 to the Turbomeca TM333 for better fuel economy and more power at altitude. I wondered if any civil operators were considering this as an option. I suspect it's probably to late in the aircrafts life.

I recall seeing an article about Rocky Mountain Helicopters having played about with a PT6 in a Llama but I don't know how far it got, probably for the same reasons of age etc.
