With a compression ratio of 8.6:1, power output is 80 hp (60 kW 81 PS) at 5500 rpm and 98 lb⋅ft (133 N⋅m) at 2500 for the 8-valve SOHC carburetted versions. It has a very high rod/stroke ratio of 2:1, bore and a stroke of 86 mm × 77 mm (3.39 in × 3.03 in). It replaced the F/NA 1.6 from the previous generation.Ī destroked FE at 77 mm (3.03 in), the 1.8 L (1,789 cc) F8 comes in several configurations including a 12-valve head and fuel injection later in its life.

Bore was as for the VC, 80 mm (3.15 in), but stroke was increased to 98 mm (3.86 in). Output varied considerably depending on market and installation, in a 1981 UK-market B1800 it is 84 hp (63 kW 85 PS) DIN at 5000 rpm and 13.7 kg⋅m (134 N⋅m 99 lb⋅ft) at 2500 rpm.
