Description
About Subaru WRX Engines
Looking for a replacement Subaru WRX engine? Part Nests stocks OEM used Subaru WRX engines across all primary variants and years. The Subaru WRX (formerly Impreza WRX) has used three primary engine generations across US production from 2002 through 2021. This overview listing covers all three variants; for specific variant deep-dives see our dedicated listings: EJ205, EJ255, and FA20DIT. All three engines share the Subaru horizontally-opposed boxer-4 architecture but differ substantially in displacement, fuel injection, turbocharger design, and timing drive.
Three Primary US WRX Engine Generations
EJ205:
- Displacement: 2.0 liters (1,994 cc)
- Power: 227 HP at 6,000 RPM, 217 lb-ft at 4,000 RPM
- Fuel system: Port fuel injection (PFI)
- Turbocharger: IHI VF-series turbo
- Timing: Timing belt (every 105,000 miles service)
- Generations: Bugeye (2002-2003), Blobeye (2004-2005)
- Significance: The first US WRX engine, defining the introduction of WRX to American buyers
EJ255:
- Displacement: 2.5 liters (2,457 cc)
- Power: 224-265 HP at 5,200-6,000 RPM, 226-258 lb-ft at 2,800-4,400 RPM
- Fuel system: Port fuel injection (PFI)
- Turbocharger: IHI VF-series turbo
- Timing: Timing belt (every 105,000 miles service)
- Block: Open-deck aluminum (vs the STI EJ257 semi-closed deck)
- Generations: Hawkeye (2006-2007), 2008-2014 sedan and hatchback, VA 2015-2018 some markets
- Significance: The 2.5L displacement increase providing more low-end torque vs EJ205
FA20DIT:
- Displacement: 2.0 liters (1,998 cc)
- Power: 268 HP at 5,600 RPM, 258 lb-ft at 2,000-5,200 RPM (broad flat curve)
- Fuel system: Direct injection (HPDI)
- Turbocharger: Twin-scroll turbocharger (modern design)
- Timing: Timing chain (no scheduled replacement)
- Compression: 10.6:1 (much higher than EJ255 8.4:1, possible due to direct injection)
- Generation: VA generation 2015 plus US WRX (sedan only)
- Significance: Modern Subaru turbo with direct injection, twin-scroll turbo, and timing chain
STI vs WRX Engine Distinction (Important Buyer Note)
This listing covers WRX engines specifically (NOT STI engines). The Subaru WRX STI has used different engines than the WRX:
- WRX (this listing context): EJ205 (2002-2005), EJ255 (2006-2014, 2015-2018 some markets), FA20DIT (2015 plus US market)
- STI: EJ257 (2004-2021 all US STI years); STI did NOT transition to FA20DIT – STI continued with EJ257 through end of US production in 2021
- WRX vs STI is NOT cross-compatible: WRX engines cannot be cross-applied to STI without substantial supporting modifications; STI engines cannot be cross-applied to WRX without supporting modifications
- Calling to specify is essential: Call (855) 634-4447 to specify WRX vs STI and exact year before ordering

WRX vs Forester XT and Outback XT
The Subaru WRX engines (this listing) also share lineage with Forester XT and Outback XT applications:
- Forester XT (US market 2004-2018): Used EJ205 (2004-2005), EJ255 (2006-2013), FA20DIT (2014-2018) – largely paralleling WRX engine generations
- Outback XT (US market various years): Used EJ255 and FA20DIT in turbo Outback variants
- Legacy GT (US market 2005-2009): Used EJ255 paralleling WRX EJ255 era
- Cross-application: WRX engines have been used in Forester XT, Outback XT, and Legacy GT applications with appropriate ECU and accessory drive verification
Subaru Boxer Engine Family Context
The Subaru WRX engines (this listing) cover the WRX engine family across US production years. For specific variant listings across our catalog and prior batches: the Subaru EJ205 engine (our listing) covers EJ205 specifically; EJ255 covers 2.5L turbo for mid-life US WRX; FA20DIT covers modern direct-injection turbo. The Subaru EJ25 Turbo engine covers broader EJ25 Turbo family. The Subaru EJ257 engine covers STI Turbo (NOT WRX). The Cosworth EJ257 crate engine is Cosworth-built STI upgrade. The Subaru BRZ engine uses FA20D NA variant – related FA family for NA sport coupe. The Subaru TR580 transmission is modern WRX CVT pairing with FA20DIT. From : EJ25, FA20, and FB25 modern FB family NA successor.

Three primary US WRX engine generations covering 2002 through 2021. The Subaru WRX (formerly Impreza WRX) has used three primary engine generations across US production from 2002 through 2021. EJ205, EJ255, FA20DIT. All three engines share the Subaru horizontally-opposed boxer-4 architecture but differ substantially in displacement, fuel injection, turbocharger design, and timing drive. The 2022 plus VB generation US WRX uses a newer FA24F engine (not covered in this listing). For specific variant deep-dives see our dedicated listings / /.
Three transitions: EJ205 in 2002, EJ255 in 2006, FA20DIT in 2015. 2002 US WRX: EJ205 (Bugeye generation, first US WRX year). 2003 US WRX: EJ205 (Bugeye). 2004 US WRX: EJ205 (Blobeye generation begins). 2005 US WRX: EJ205 (Blobeye, final EJ205 year). 2006 US WRX: EJ255 transition (Hawkeye generation begins; 2.5L displacement increase). 2007 US WRX: EJ255 (Hawkeye). 2008-2014 US WRX: EJ255 (sedan and hatchback variants). 2015-2018 US WRX: FA20DIT (VA generation sedan, direct injection introduction). 2019-2021 US WRX: FA20DIT (VA generation continued). 2022 plus US WRX: newer FA24F engine (not covered in this listing). Call (855) 634-4447 to specify your exact year before ordering.
WRX uses EJ205 / EJ255 / FA20DIT while STI uses EJ257 only. This listing covers WRX engines specifically (NOT STI engines). The Subaru WRX STI has used different engines than the WRX. WRX (this listing context): EJ205 (2002-2005), EJ255 (2006-2014, 2015-2018 some markets), FA20DIT (2015 plus US market). STI: EJ257 (2004-2021 all US STI years); STI did NOT transition to FA20DIT - STI continued with EJ257 through end of US production in 2021. WRX vs STI is NOT cross-compatible: WRX engines cannot be cross-applied to STI without substantial supporting modifications. Calling (855) 634-4447 to specify WRX vs STI and exact year before ordering is essential.
Shared engines across WRX, Forester XT, Outback XT, and Legacy GT. The Subaru WRX engines (this listing) also share lineage with Forester XT and Outback XT applications. Forester XT (US market 2004-2018): used EJ205 (2004-2005), EJ255 (2006-2013), FA20DIT (2014-2018) - largely paralleling WRX engine generations. Outback XT (US market various years): used EJ255 and FA20DIT in turbo Outback variants. Legacy GT (US market 2005-2009): used EJ255 paralleling WRX EJ255 era. Cross-application: WRX engines have been used in Forester XT, Outback XT, and Legacy GT applications with appropriate ECU and accessory drive verification. Calling (855) 634-4447 to verify cross-application is essential.
Direct injection, timing chain, twin-scroll turbo introduced with FA20DIT. The most significant architectural difference is the transition from EJ family (EJ205 / EJ255) to FA family (FA20DIT) in 2015. EJ family (EJ205 2002-2005 and EJ255 2006-2014): port fuel injection, timing belt every 105,000 miles, IHI VF-series single-scroll turbo, 8.0-8.4:1 compression. FA20DIT (2015 plus): direct injection HPDI, timing chain (no scheduled replacement), twin-scroll turbocharger, 10.6:1 compression. Each transition between EJ205 to EJ255 (2006) and EJ255 to FA20DIT (2015) brought specific architectural advances. Service requirements differ accordingly: EJ family needs timing belt service every 105,000 miles; FA20DIT needs walnut shell blasting carbon cleaning every 60,000-100,000 miles.
Multiple Subaru engines across batches 29-30 with WRX as key application. The Subaru WRX engines (this listing) cover the WRX engine family across US production years. references: EJ205 (US WRX 2002-2005 specifically), EJ255 (US WRX 2006-2014 plus some 2015-2018), FA20DIT (US WRX 2015 plus), EJ25 Turbo broader family, EJ257 STI Turbo (NOT WRX), Cosworth EJ257 STI upgrade, Subaru BRZ engine (FA20D NA), TR580 transmission (modern WRX CVT), FB25 modern FB family NA. references: EJ25 broader family, FA20 broader FA20 family.
Variant-specific. EJ205 / EJ255: head gasket, timing belt, turbo, AVCS. FA20DIT: carbon cleaning, HPDI, oil consumption check. After acquiring a used Subaru WRX engine, budget based on variant. EJ205 and EJ255: head gasket assessment $1,500-3,500 proactive MLS replacement with ARP head studs, timing belt service $800-1,500 every 105,000 miles critical, turbo inspection $1,500-3,500 if at high mileage IHI VF-series wear 100,000-150,000 miles, AVCS solenoid inspection, strict synthetic oil 3,000-3,750 mile intervals for turbo, premium 91 octane minimum. FA20DIT: carbon cleaning $600-1,200 walnut shell blasting every 60,000-100,000 miles (CRITICAL for direct injection), HPDI fuel pump inspection $800-1,500 replacement if failing, direct injector inspection cleaning service, oil consumption check verify Subaru service campaign completion on early VINs, strict synthetic oil 3,000-3,750 mile intervals.
