Apply: 2.2L
Stroke: 79.0mm (normal 75.0mm)
weight: 9.4kg (normal 9.4kg)
heat treatment distortion is extremely small, the change in metal protection
size is very small, high output is no core hardness reduction of the corresponding
material, excellent in high rotation corresponding
abrasion resistance versus seizure resistance and fatigue strength, durability
Remarks:
Only the piston need
EJ20 because metal width is narrow (16.5mm), it is difficult to secure the metal strength, it has been reported many engine trouble due with a metal baking. Then subjected to Parusonaito processing in order to increase the surface hardness, and is raising the metal protection.
