Engine Family:
Likely based on Suzuki 4-stroke engines for many of these models, particularly the 660cc and turbo variants. Specific engine details would vary by model within this manual.
Engine Displacement:
Common displacements for this era include 660cc (typically naturally aspirated and turbocharged variants). The Jaguar Z1 likely features a larger displacement, possibly around 1000cc or more, depending on its specific engine. The AC 120 would have a smaller displacement engine.
Engine Configuration:
Inline 3-cylinder for 660cc models is common. The Z1 engine configuration will be specified within the manual.
Engine Cooling:
Liquid-cooled
