EJ22 Engine

Beginning in the 1997 Model Year, the ej22 2.2 liter engine for 1997 Legacy and Impreza models has had internal and external changes that yield an approximately 10% increase in power and 3% increase in fuel economy.

Accomplishing this involves many factors, one of which is ej22 engine friction reduction. The piston, a major source of engine friction, has been coated with a friction reducing agent called Molybdenum. This thin coating not only allows smoother travel through the cylinder, but also reduces cylinder wall scuffing.

The skirt of the piston has been reshaped and the overall weight has been reduced by approximately 100 grams. Compression ratio on ej22 has been increased to 9.7 to 1 by reshaping the crown of the piston. This eliminates the clearance that was available between the piston at TDC and the fully opened valve.

Piston pin offset has been changed to 0.5 mm (0.0 in). Piston to cylinder wall clearance has been reduced by increasing the piston diameter.

Another source of the high ej22 engine friction is the valve train. Hydraulic lash adjusters (HLAs) are always in contact with the valves. The hydraulic pressure of the lash adjuster must be overcome during operation and during the most critical time of engine start.

To overcome this situation and to contribute to the total reduction of friction loss, 1997 and later SOHC ej22 engines have solid valve adjusters. The scheduled service of this valve train is set at 100,000 miles (160,000 km). SOHC engines now use an adjustment screw to adjust valve clearance.

The roller rocker cam follower system that was introduced on the 1.8L Impreza engines, is installed on all 1995 model year and later 2.2 liter engines. The roller assemblies are not serviceable separately, but the rocker arms may be serviced as individual units.

The carbon composition head gaskets with integrated o-rings are interchangeable from left to right on 1990 to 1994 N/A engines only.

Other EJ22 Engine Modifications (2.2L 1997) The intake manifold has been reshaped to increase the airflow mass and speed, contributing to improved low and mid engine speed operation. Components located on the intake manifold have been relocated as compared to the 1996 models. EGR Solenoid, Purge Control Solenoid, etc.

1999 2.2 Liter Phase 2 Engine Enhancements: All 2.2 liter engine for 1999 are the Phase 2 design. The ej22 2.2 liter Phase 2 engines are a SOHC design, with a newly-designed cylinder head
