The Rolls-Royce RB.183 Tay is a development of the RB.163 civil Spey, using the low-pressure components from the famous RB.211 to produce a version with a bypass ratio increased to 3. It was initially developed as the Spey Junior. The Tay has been used on a number of small airliners and larger bizjets, including the Gulfstream IV, Fokker F70 and Fokker F100, with later versions being used to re-engine Boeing 727's.
