In took an extended while but the twin-turbo EJ20 engine emerged in Australia onboard the MY02 Liberty B4. The freedom B4 has a similar mechanical configuration since the Japanese-spec Edition but, once again, the engine mapping is detuned to match ninety eight RON gasoline. Output is 190kW and 320Nm - with 278Nm out there from just 2000 rpm. A five-pace handbook or even a 4-velocity auto was presented. Apparently, the B4 twin-turbo in no way obtained adequately recognized within the Australian marketplace and was axed adhering to the MY03 Variation. Changing the B4 is the freedom GT sedan and wagon which ended up unveiled in late 2003 (with the 2004 product 12 months). The freedom GT reverts back again to an individual turbo process together with AVCS cam timing Management plus a 9.5:one static compression ratio. Additionally, there are many internal modifications. Output isn’t as powerful as the superseded B4 – however it’s not considerably off. The only turbo Liberty GT pushes 180kW and 310Nm at a low 2400 rpm (just 10kW and 10Nm down within the B4).
On a regular basis keeping and replacing the air filter is an easy still critical aspect of Subaru EJ20 treatment. It’s an expenditure within your engine’s well being and performance, guaranteeing it continues jogging effectively with the prolonged haul.
The Subaru EJ20 engine is really a testomony on the manufacturer’s motivation to precision engineering and effectiveness.
Corrosion Prevention: The correct coolant mix inhibits rust and corrosion that could problems the engine.
In its most elementary Normally aspirated kind, the EJ20 generates close to 150 horsepower. Even so, when turbocharged and intercooled in styles like the WRX STI, it may develop upwards of three hundred horsepower.
The MY99 and MY00 Edition five and 6 STis have exactly the same 206kW/353Nm output but we consider there may well are actually some slight adjustments (like camshaft profile).
Turbocharged versions in the EJ20, such as All those found in the WRX and STI styles, come Outfitted having an intercooler to reduce the air consumption temperature, therefore increasing density and letting For additional electrical power.

These engines are depending on exactly the same engine platform; the X is selected to point an computerized, as well as Y suggests a handbook one particular. The EJ20X was released while in the 2003 Legacy GT matched to the five-velocity automatic transmission.
There was no car trans alternative while in the early WRX but you might purchase a wagon Variation which was detuned to 162kW/280Nm (which means, at minimal, the WRX engine has equal or increased electricity and torque in contrast the modern day Legacy styles).
the intake rocker arms are marked so They may be appropriately placed on the rocker shaft when servicing. An IN1 or IN2 might be embossed on each rocker arm. As considered with the entrance with the engine the Number one consumption valve of each and every cylinder along with the number two ingestion valve have an IN1 marked and IN2 marked rocker arm that mates with it.
The EJ204 is really a period two engine also that features DOHC cylinder block heads. It utilised an AVCS variable valve timing program about the intake camshaft in addition to a fifty-degree adjustment vary. The EJ204 has an influence of a hundred and fifty five HP, and there are one hundred eighty HPs out there too.
Other engine modifications (1997): The intake manifold continues here to be reshaped to enhance the airflow mass and pace, contributing to enhanced reduced and mid engine pace Procedure.
When discussing the EJ20’s lifespan, it’s essential to think about how its sturdy layout and suitable upkeep converge to define its lengthy-time period performance.
