The Leyland PE166 (often referred to as the Rover-Triumph Straight Six) is a single overhead camshaft (SOHC) Straight-six engine developed by the Rover-Triumph division of British Leyland, and was exclusively used in the Rover SD1 (Rover 2300/Rover 2600) series of vehicles between 1977 and 1986. Technical detail The engine was loosely based on the older Triumph I6 (which it was intended to replace), and was initially intended to share some internal components with that and the Dolomite Sprint engines. However, during development not a single component remained unchanged, the last link being severed when the conrod big-end was increased in diameter over the Dolomite Sprint equivalent. Both the capacity variants use an bore, with a or stroke giving capacity respectively. The 2350cc engine produces a maximum power of 118 PS (116 bhp - 87 kW) at 5000 rpm and a maximum torque of 163 Nm (120 lb. ft) at 3500 rpm. On the other hand, the 2.6 L engine produces a maximum power of 138 PS (136 bhp - 101 kW) at 5000 rpm and a maximum torque of 206 Nm (151 lb.ft) at 3750 rpm.
