The Subaru EJ20 engine, celebrated for its reliability and engineering, comes along with varying horsepower rankings based on the product and calendar year.
Additionally, the firing get is ready To optimize the performance from the exhaust scavenging method. It helps in successfully clearing the combustion chambers of exhaust gases, which is particularly helpful in turbocharged EJ20 variants, since it permits a far more quick intake of refreshing air, Hence enhancing the engine’s efficiency and energy output.
Like we described above, the EJ20 series became prosperous as a result of its tuning and enhance potentials. Having said that, I hope it is clear that rising the power of a Obviously aspirated EJ20 is non-perception.
The spark plug is a small but essential part in an engine’s overall performance and effectiveness. For your Subaru EJ20 engine, utilizing the proper spark plugs and environment the correct hole can considerably influence engine response and In general functionality.

In Australia, the MY03 is the very first non-STi WRX to use the AVCS cam timing technique. The compression ratio is additionally elevated from eight to nine:1 for enhanced drivability. This leads to an additional 6kW (168kW at 6000 rpm) and torque boosts by 3Nm (there’s 300Nm at 3600 rpm). Ninety-eight RON unleaded is suggested for this engine and, for The 1st time, a sequential automated transmission was introduced.
