In took a protracted when but the dual-turbo EJ20 engine emerged in Australia onboard the MY02 Liberty B4. The Liberty B4 has the exact same mechanical configuration since the Japanese-spec Variation but, once again, the engine mapping is detuned to fit ninety eight RON gasoline. Output is 190kW and 320Nm - with 278Nm obtainable from just 2000 rpm. A 5-velocity manual or possibly a 4-velocity vehicle was supplied. Apparently, the B4 twin-turbo never acquired adequately established inside the Australian marketplace and was axed adhering to the MY03 Model. Replacing the B4 is the Liberty GT sedan and wagon which ended up introduced in late 2003 (for your 2004 model 12 months). The Liberty GT reverts back to an individual turbo process along with AVCS cam timing Regulate and a 9.five:1 static compression ratio. There's also various internal improvements. Output isn’t as solid since the superseded B4 – but it surely’s not considerably off. The only turbo Liberty GT pushes 180kW and 310Nm in a minimal 2400 rpm (just 10kW and 10Nm down to the B4).
Additionally, the firing buy is about To maximise the performance of your exhaust scavenging process. It can help in competently clearing the combustion chambers of exhaust gases, which is especially beneficial in turbocharged EJ20 variants, mainly because it permits a more quick consumption of refreshing air, Hence strengthening the engine’s efficiency and electricity output.
This may confuse you, particularly if you happen to be dealing with The difficulty outlined above in too much oil use.
A five-velocity Sportshift car arrives normal inside the MY04 Liberty GT – there was no manual option right up until the MY05 version. The MY05 Liberty GT guide also provides much more grunt compared to the car versions – 190kW and 330Nm. Oh, and don’t forget about the community Forester GT which appeared to the 1999 model 12 months. The Forester GT makes use of a comparatively minimal output Variation on the EJ20 turbo – it utilizes an eight.five:1 static compression ratio, a small turbocharger and intercooler, rather tame camshafts plus a conservative ECU tune. Max output is 125kW and there’s 240Nm at just 3200 rpm. A 5-speed manual or 4-velocity auto arrives equipped. For the MY01 Edition output was amplified 5kW and 5Nm. This came from altered cylinder head consumption ports with Tumble Generator Valves, a larger turbine housing, fitment of the pre-turbo cat converter and up-to-date engine administration and ignition methods. The 2.five-litre engine replaces the EJ20 in the current Forester XT.
This two-liter Variation laid down the history of the EJ collection. The EJ20 changed the previous EA82 1.eight-liter engine and became the main engine option for many Subaru models for a long time.
The engine characteristics an aluminum alloy block and heads to lower weight without having compromising energy. Its dual overhead camshaft (DOHC) style and design with four valves for each cylinder boosts airflow and makes it possible for the engine to breathe more competently, causing greater throttle response and better energy output.

The EJ20’s dependability can also be mirrored in the Local community of fans and specialists who winner website its endurance. It's a typical sight in motorsport, which speaks volumes about its resilience less than nerve-racking ailments.
However, reaching these large mileage milestones relies on adhering to some rigid servicing program. This features well timed oil modifications with substantial-excellent oil, frequent timing belt replacements, and making sure the cooling system is functioning optimally to prevent the infamous head gasket challenges.
These plugs are meant to last lengthier, resist fouling, and supply a secure spark, which is particularly critical for turbocharged engines or subjected to significant-general performance driving disorders.
Unlike most 4-cylinder engines, it's got a very low rumble that ascends into a growl as you make your way through the RPMs. When you listen to a Subaru engine, there isn't any doubt that you are Listening to a Subaru engine. They're identifiable from miles absent.
This design is chosen as it allows for larger valves and higher compression ratios, contributing to higher engine overall performance and effectiveness.
Other engine modifications (1997): The intake manifold has actually been reshaped to boost the airflow mass and velocity, contributing to improved lower and mid engine velocity operation.
Subaru endorses using synthetic oil for the EJ20 engine to supply the most beneficial defense and efficiency, In particular beneath extreme disorders or efficiency driving.
