Simon,
Just one thing, if you are going to go initially by the FAA system then there is no such thing as a "turbine Rating" (a/c <12,000 lbs). You can however get a turbine
transition , which can vary in length from approx 3-10 hours depending on a/c and when the owner/operator/check pilot thinks you are up to speed.
Good Luck!
