The EJ205 is also a favorite of the creative minds of the automotive world since the robust design allows for significant power increases.

Compact and lightweight, the EJ205 is also an ideal choice for engine swaps. So if you’re looking to replace a naturally aspirated motor or get that Subaru sitting in the garage back on the road, the EJ205 engine for sale here is what you need.

Important Specification Correction

The live product page header lists the EJ205 specifications as 130 HP and 133 lb-ft. These are NOT actual EJ205 specifications , the EJ205 is a turbocharged engine producing significantly higher output. The actual EJ205 specifications:

EJ205 in US WRX (2002-2005): 227 HP at 6,000 RPM, 217 lb-ft at 4,000 RPM

EJ205 in Forester XT (2004-2005): 210 HP at 5,600 RPM, 235 lb-ft at 3,600 RPM

The 130 HP / 133 lb-ft figures correspond to naturally aspirated EJ20 variants (such as the EJ201 or EJ202 used in base / JDM applications). The EJ205 is fundamentally a turbocharged engine and cannot produce its rated output without the turbocharger.

If you require a non-turbo 2.0L EJ20 variant instead of the turbocharged EJ205, please call (240) 301-0095 for variant clarification.

Engine Overview: Subaru EJ205 (2.0L Turbocharged DOHC)

The Subaru EJ205 spent most of its days powering the original US Subaru WRX (2002-2005), where it earned its iconic status. One of the reasons this engine is a favorite of enthusiasts is its ability to perform both as a daily driver and for spirited driving. Being a Subaru engine, the 2.0L EJ205 has a boxer configuration, giving the WRX a lower center of gravity and balanced performance. Even though the engine is compatible with various upgrades, the durability of the bottom end is impressive for a high-performance turbocharged engine of its era.

EJ205 Specifications

The EJ205 vs EJ25 Turbo Family Comparison

The EJ205 is part of Subaru’s 2.0L turbocharged engine family (EJ20-T), which is distinct from the larger 2.5L EJ25 turbo family:

The EJ205 was replaced by the EJ255 in 2006 when the WRX upgraded to 2.5L turbo for more torque and tunability.

Vehicle Applications (Direct Fit)

The Original US WRX Heritage (2002-2005)

The EJ205 powered some of the most beloved Subarus ever sold in the US:

2002-2003 “Bug-Eye” WRX

HP: 227 HP (EJ205)

Style: Original “bug-eye” front fascia

Significance: The first US-market Subaru WRX, introducing American buyers to rally-derived AWD turbo performance

Cult following: Strong enthusiast community to this day

2004-2005 “Blob-Eye” WRX

HP: 227 HP (EJ205 with VF39 turbo)

Style: Updated “blob-eye” front fascia

Improvements: Refined chassis, updated suspension

Significance: Refined version of the original US WRX

2004-2005 Forester XT (First 2 Years)

HP: 210 HP (EJ205 with VF38 turbo)

Significance: First Forester turbo variant, brought WRX-style performance to the Forester platform

Position: Performance Forester before the EJ255 transition in 2006

Key Engineering Features

Flat-4 Horizontally Opposed Boxer Configuration: Subaru signature architecture

DOHC Per Bank: Dual overhead camshafts, 16 valves total

AVCS Variable Valve Timing on Intake: Active Valve Control System on intake camshaft only (the EJ205 does NOT have AVCS on exhaust , this was added on the later EJ255/EJ257)

IHI VF-Series Turbocharger: Quality Japanese turbocharger (VF35, VF39, or VF38 depending on application)

Top-Mount Intercooler (TMIC): Mounted on top of the engine

Open-Deck Aluminum Block: Lightweight construction

Premium Fuel Required: 91 octane minimum, 93 recommended

The AVCS Intake-Only Detail (Important)

A key difference between the EJ205 and the later EJ255 / EJ257 is the AVCS variable valve timing implementation:

EJ205: AVCS on intake camshaft only

EJ255 / EJ257: AVCS on BOTH intake and exhaust camshafts

This affects the engine’s character:

The EJ205’s intake-only AVCS provides smooth power delivery and good low-RPM torque

The EJ255/EJ257’s dual-cam AVCS provides more precise control of exhaust events for better top-end power and emissions control

For tuning, the EJ205 is more limited in valve timing strategies than the later variants

Common EJ205 Service Items (Honest Disclosure)

The EJ205 has well-documented service items typical of EJ-series turbo engines:

Ringland Failures

The most well-known EJ-turbo weakness. Cast pistons can develop ringland failures (the lands between piston rings crack), causing loss of compression and engine failure. Risk factors:

High boost levels (over 16-18 PSI on stock EJ205 pistons)

Detonation (low octane fuel, poor tuning, lean conditions)

Modified engines without supporting upgrades

Mitigation: Use premium fuel always, avoid detonation, proper tuning if modified, conservative boost levels on stock pistons, forged pistons for any serious build.

Connecting Rod Bearing Wear

At high mileage, rod bearing wear becomes documented. Cast rods are similar to those used on EJ255. Symptoms: rod knock at startup or under load.

Head Gasket Failures

Less common than NA EJ-series but documented at high mileage. Open-deck block design contributes. MLS gaskets at any installation.

Banjo Bolt Screen Blockage

Common cause of turbo oil starvation on EJ-series turbo engines. Should be inspected at any service interval.

Turbocharger Service Items

VF35 / VF39 / VF38 are durable but age: Bearing wear, oil seal leaks at high mileage

Bearing service or replacement: Often needed at 100,000-150,000 miles

Other Items

Front main seal leaks: At high mileage

AVCS solenoid (intake): Occasional failures

Spark plug service: 30,000-60,000 mile intervals
