Stage I
Without altering the displacement (1,166 cc), the pistons have been established to increase the compression ratio.
Cylinder Head Gasket, Piston & Piston Rings
(1) Main modifications
- a. Cylinder head gasket.
- Due to increase of compression ratio, the thickness upon assembling has been revised.
- b. Piston
- Without altering the displacement (75Ø 1,166cc), the compression ratio has been incrased.
- c. Piston rings.
- Two compression rings with thickness of 1 mm are utilized and the oil ring is of three-piece type with the thickness of 2.5mm.
