Suspected, the source comes from the use of improper fuel. Unless PERTAMAX Racing, it was only 2 gas stations in the Jakarta area. For fuel sold freely in the country, it is still less value octane for Subaru engines.
Then, should re-mapping the ECU adjusts octane available in the domestic market?
Carefully modified Subaru engine. Read carefully the instructions made ??by the APM. But the case is not just overwrite the vehicle that has been modified. Still the standard and not long out of the showroom was affected, damaged piston
It can be seen from the manual that the Subaru WRX STI requires a minimum of 98 octane, while in Indonesia there are only a maximum of 95 octane Surely PERTAMAX Subaru Racing able to meet the criteria but it is not among the common fuel
Could be a broken piston ring material is not strong or timing advance for 98 octane, but strangely no symptoms knocking sound. Perhaps as a result of the boxer character voices tend to be noisy so disguise knocking noise
Entering the valve can get damaged piston impact. Forced to replace the valve as well if you want a normal compression. Costs are not cheap because octane error should be considered carefully before buying a vehicle
Part liner block berets also severely hit by the shards of the piston and rings. Forced to oversize the diameter of the piston and liner blocks.
