In Australia, the EJ208 engine was introduced in the 2001 Subaru BE Liberty B4 which, with a manual transmission, produced peak outputs of 190 kW and 320 Nm. From 2002, the BE Liberty B4 was offered with an automatic transmission for which the EJ208 engine was detuned for ‘smooth torque delivery’ and to avoid ‘shift shock’ on gearchanges. The EJ208 engine had a die-cast aluminium alloy cylinder block with 92. 0 mm bores and a 75. 0 mm stroke for a capacity of 1994 cc. For the EJ208 engine, the crankshaft was supported by five bearings that were made from aluminium alloy.
The EJ208 engine had cast connecting rods and forged aluminium pistons which weighed 162 grams each. Reduced top land to cylinder clearance. The piston crowns for the EJ208 engine had flat tops for a compression ratio of 9. For quiet operation, the teeth on the timing belt had a round profile. The recommended replacement interval for the cam belt was 100,000 kms or four years, whichever occurred first.
The EJ208 cylinder head had four valves per cylinder that were actuated by solid valve lifters. The intake valves had hollow stems to reduce mass and inertia, while the exhaust valve stems were filled with sodium. At high temperatures, the sodium would liquefy and its motion within the stem would effectively transfer heat from the valve head to the valve stem, contributing to faster cooling of the valve head. 4 grams each, while the exhaust valves weighed 46. Initially, pressure generated by the secondary turbocharger was redirected to the inlet side of the air intake.
Secondary stage twin turbo operation: when the ECM determined that engine operating conditions were suitable, the relief valve would close and the exhaust gas control valve would fully open. When the intake control valve was opened, pressure from the secondary turbocharger was supplied to the intercooler. During this stage, boost pressure control was regulated via the primary turbocharger’s wastegate. During this phase, exhaust pressure previously only supplied to the primary turbocharger is now supplied to both the turbochargers, leading to a temporary and slight reduction in primary boost pressure. In testing by Autospeed, however, a ‘significant dip in manifold boost pressure’ of 0. 30 bar was observed during the 4000-4500 rpm transition.
It is understood that peak boost pressure for the EJ208 engine was 0. To reduce the temperature of the intake air after it was compressed by the turbocharger, and increase the density of the intake charge, the EJ208 engine had a Sanden intercooler which had a cooling capacity of 13. The EJ208 engine had computer controlled, multi-point sequential fuel injection system with 550 cc injectors. The injection and firing order for the EJ208 engine was 1-3-2-4.

Please note that this article considers the EE20 engine as it was supplied in Australian-delivered vehicles.
As such, it does not consider the Euro 4 emissions compliant EE20 engines that were available in Europe. Furthermore, specifications for other markets may differ from those in Australia. The EE20 engine was manufactured on the same assembly line as Subaru’s six-cylinder horizontally opposed petrol engines at its Oizumi factory. The EE20 engine had an aluminium alloy block with 86. 0 mm bores and an 86. 0 mm stroke for a capacity of 1998 cc. For the Euro 6 EE20 engine, however, an open deck design was adopted which eliminated the 12 and 6 o’clock supports.
