What size rod is a EJ20?

The EJ20 engine, commonly found in Subaru vehicles, typically uses a 2.0-liter piston rod. This rod size is designed to handle the engine's displacement and power output.


Explaining the EJ20 Engine


The EJ20 is a 2.0-liter flat-four (boxer) engine produced by Subaru. It was first introduced in 1989 and has been used in a variety of Subaru models, including the Impreza, Legacy, and Forester. The EJ20 is known for its reliability, performance, and the distinctive sound of its boxer configuration.


Piston Rod Size


The piston rod, also known as the connecting rod, is a crucial component that connects the piston to the crankshaft. The size of the piston rod is determined by the engine's displacement and the expected power output. For the EJ20 engine, the typical piston rod size is 2.0 liters, or 2.0L.



  • The EJ20 engine has a bore (cylinder diameter) of 92 mm and a stroke (piston travel) of 75 mm, resulting in a total displacement of 1,994 cc (2.0 liters).

  • The piston rod length is designed to match the engine's stroke and provide the optimal connecting geometry for efficient power transfer.

  • The piston rod material is typically forged steel or aluminum alloy, depending on the specific EJ20 variant, to balance strength, weight, and cost considerations.


The 2.0-liter piston rod size is a key component that allows the EJ20 engine to deliver its characteristic performance and reliability in Subaru vehicles.

Is EJ20 SOHC or DOHC?


The EJ20X and EJ20Y engines had an aluminium alloy cylinder head with cross-flow cooling, double overhead camshafts (DOHC) per cylinder bank and four valves per cylinder that were actuated by roller rocker arms.
