Camshaft rear plastic thrust plate o-ring weeping and hydraulic lifter ticking cause chronic oil loss across older courier wagons. The Subaru Legacy Impreza EJ22E 2.2L H4 Engine eradicates boxer valvetrain chatter during commercial long block repower jobs. This 4-Cylinder 135HP horizontal powerplant demands manual wrist pin access plug sealant verification before mating the rear separator plate.

Die-cast A356-T6 aluminum forms the horizontally opposed crankcase bearing EJ22 stamps on the right front top deck. Centrifugal cast iron liners contain cast aluminum pistons pinned to a micro-polished 4140 forged steel crankshaft spinning in tri-metal main shells. This Subaru engine core demands a 12V 140A starter draw during cold morning starts. Dry engine weight measures 185 lbs inside a 24in length, 28in width, 22in height frame holding 4.2 quarts of oil.

Key Features of Subaru EJ22E 2.2L

Commercial transport fleets buy Subaru Legacy Impreza EJ22E 2.2L H4 Engine packages to avoid remote breakdown costs. Our industrial engine rebuild standard upgrades all rear oil separator covers to stamped steel units with heat-resistant Viton perimeter gaskets.

- Cylinder bores measure 3.815in with diamond plateau hone cross-hatch finishes.
- Main bearing journal clearance holds at 0.0014in across the five-journal boxer crankcase.
- Single overhead camshaft lobes pass dynamic Rockwell hardness tests to prevent flat-spot wear.
- Cast iron camshaft thrust plates replace failure-prone factory composite end covers.
- Multi layer steel head gaskets eliminate cylinder deck combustion gas intrusion.
- This EJ22 commercial core features cylinder head decks surfaced flat to 0.0003in.
- Induction-hardened valve seat inserts resist unleaded gasoline recession wear.

Dynamometer Load Station Records

Automated brake cell test logs demonstrate that this EJ22 long block engine produces 135 continuous BHP and 140 ft-lbs of torque at 4400 continuous load RPM. Internal oil gallery pressure measures 52 PSI while oil sump temp levels at 190°F under sustained brake loading. Exhaust gas temp tops at 1220°F down the test manifold runner. Cylinder compression reads between 175 PSI and 182 PSI across all four chambers. Crankshaft center journal runout holds within 0.0002in TIR.

Verified Chassis Fitment Application Matrix

This remanufactured boxer motor installs into October 1993 through May 1995 Subaru Legacy BD sedan and BG wagon chassis. It also integrates into first-generation GC and GF Impreza models paired with five-speed manual or four-speed automatic all-wheel-drive transaxles utilizing single-port exhaust manifolds and front-mount crank angle triggers.

Field Installation Operational Limits

Throttle quadrant cable mechanisms demand 4 lbs of linear pull force to guarantee complete throttle plate closure at idle. This naturally aspirated non-interference engine is not engineered for turbocharged performance conversions, aircraft power conversions, marine hulls, or stationary generator pump skids.

- Drain initial break-in petroleum motor oil after 500 miles or 30 run hours.
- Bleed hydraulic lash adjusters in clean engine oil prior to rocker arm installation.
- Torque cylinder head bolts in six stages to 51 ft-lbs final specification.

Commercial Protection Crate Manifest

Certified under our Subaru assembly standard, this crate engine carries a 3-Year 100,000-mile parts protection warranty. Every sealed wooden crate holds the complete long block core, steel oil pan, aluminum water crossover pipe, valve covers, oil pickup tube, and signed dyno load sheet.
