I am looking at buying a F33A which is turbonormalised. Does anyone have
any knowledge about the value this adds to the aircraft. I know the cost of
fitting but this one was done in 1991, and it is the original turbo. How
much does it add to the value of the basic aircraft?

Email John Deakin of AvWeb. IIRC, that is what he flies and writes
about.
