In took a long although but the dual-turbo EJ20 engine emerged in Australia onboard the MY02 Liberty B4. The freedom B4 has the same mechanical configuration as the Japanese-spec Edition but, again, the engine mapping is detuned to fit ninety eight RON fuel. Output is 190kW and 320Nm - with 278Nm offered from just 2000 rpm. A five-velocity manual or possibly a 4-speed vehicle was provided. Interestingly, the B4 twin-turbo by no means got adequately recognized from the Australian marketplace and was axed following the MY03 Model. Replacing the B4 is the freedom GT sedan and wagon which have been unveiled in late 2003 (to the 2004 product 12 months). The freedom GT reverts again to an individual turbo process together with AVCS cam timing Management along with a nine.five:one static compression ratio. You can also find numerous inner changes. Output isn’t as sturdy given that the superseded B4 – but it really’s not significantly off. The only turbo Liberty GT pushes 180kW and 310Nm at a small 2400 rpm (just 10kW and 10Nm down within the B4).
Artic_photo/Shutterstock Placing aside the above mentioned contemplating, As with every more mature engine, there are some concerns to Be careful for. Most pertinently, the EJ20 has a tendency to take in oil inside a turbocharged format. Piston rings can become stuck, making it possible for oil to pass through to the combustion chamber.
The Subaru EJ20 engine can be a testament to your producer’s commitment to precision engineering and performance.
Several have an extra intake air temperature sensor through the throttle entire body. Its operate has become reviewed but not totally clarified.
When troubleshooting the EJ20 engine, it’s important to diagnose troubles properly to use the correct correct. Frequent maintenance can be very important to stop these troubles from developing.

The passenger intake camshaft is notched get more info to spin the scavenge pump. The oil pan has an extra mounting bolt and on the list of oil pan bolts modified position when compared with the opposite versions in the EJ255.
WRX output remained the exact same until eventually the 2005 introduction on the limited version WRX WRP10. Utilizing an update ECU and absolutely free-flow exhaust, output is improved to 175kW (a achieve of 8kW around The bottom WRX). The WRP10 goes into the record books for getting the most powerful EJ20 turbo engine within an Australian-spec WRX; the MY06 product takes advantage of a two.5-litre engine. While in the STi selection, Australia initially gained the MY99 Edition 5 two-doorway and MY00 Model 6 4-door designs. These engines keep the Japanese-spec mechanicals but are detuned to go well with Australian gas – so real output is probably less than the claimed 206kW/353Nm.
Flat four EJ251 The EJ251 was the very first version of the two.5L solitary overhead cam (SOHC) engine line by Subaru for the US market. The EJ251 was changed with the EJ253 in many designs because of its enhanced cooling to aid in head gasket life and enhanced engine administration and sensors. The EJ251 normally knowledgeable head gasket failures in the shape of interior channel breaches or exterior fluid leaks due to the usage of a single layer coated gasket, vs the Multi-Layer Metal (MLS) gasket Employed in later on models.
And the main of these types of engines may be the EJ20G. It really is amid the initial to utilize turbocharger and oil nozzles, reduced compression pistons, and a shut decked block. The capability of the inventory fuel injector is 380 cc.
The EJ20 engines Outfitted which has a turbocharger are specifically noteworthy for his or her superior horsepower output, delivering an exhilarating functionality which includes made them a favorite among auto fans around the world.
The EJ20 is really a two.0-liter boxer engine, indicating the pistons travel out As well as in horizontally relative towards the crankshaft in lieu of up and down as they would in a normal inline engine set up.
Selecting the appropriate coolant and maintaining the cooling process correctly makes certain that your Subaru EJ20 engine operates proficiently, preventing overheating and maximizing its lifespan.
When speaking about the EJ20’s lifespan, it’s vital that you take into consideration how its robust layout and good maintenance converge to define its prolonged-time period performance.
