I ve bronciectasis & heard that its a progressive condition, i ve cough, for 2 years, generally how many yrs before i am likely to need transplant?

Too hard to tell.: Really need to get this answer from your doc who knows whole lot more about your personal details than us.

Please see answer: It depends on the severity of your illness and rate of decline, and a number of other considerations to assess if you are a suitable candidate for transplantation. Have you been screened for immunodeficiency, Ciliary disease and CF? Addressing the infections and underlying cause of the disease is part of the management.
