What Was Scion? — The Brand Behind the Engine
Scion was Toyota's youth-focused sub-brand, launched exclusively in the United States in 2003. The idea was straightforward: offer stylish, affordable, highly customisable cars aimed at younger buyers who wanted something different from the mainstream Toyota lineup. The brand launched with just two models — the xA hatchback and the now-iconic boxy xB — and quickly built a loyal following among drivers who valued individuality over convention.
Over the following years, Scion expanded its lineup significantly. The sporty tC coupe arrived in 2004, the xD followed in 2007, and the brand later added the iQ city car, the iA sedan, and the iM hatchback. The FR-S — co-developed with Subaru — arrived in 2012 and became Scion's most celebrated model, a lightweight rear-wheel drive sports car that earned praise from driving enthusiasts worldwide.
Despite its strong following, Toyota made the decision to discontinue the Scion brand in August 2016. Most of the surviving models were absorbed back into the Toyota lineup — the iA became the Toyota Yaris iA, the iM became the Toyota Corolla iM, and the FR-S was reborn as the Toyota 86. The tC, xB, and iQ were discontinued entirely.
Today, millions of Scion vehicles remain on the road in the United States, which is exactly why demand for a used Scion engine for sale remains consistently strong. These are Toyota-engineered engines — well-built, parts-supported, and very much worth keeping on the road.
Used Scion Engine Specs — Every Model Covered
Scion xA Engine (2004–2006)
Displacement: 1.5L | Power: 103 hp | Torque: 101 lb-ft | Engine Code: 1NZ-FE | Config: Inline-4, DOHC | Production: 2004–2006
The Scion xA used Toyota's proven 1NZ-FE 1.5-litre four-cylinder engine — the same unit found in the Toyota Echo and early Yaris. Producing 103 hp and 101 lb-ft of torque, it was never about outright performance, but what it lacked in power it made up for in reliability and fuel efficiency. The 1NZ-FE is one of Toyota's most dependable small engines ever built. A used Scion xA engine is a straightforward, affordable replacement that will give tens of thousands of additional miles when properly installed.
Scion xB Engine — First Gen (2004–2006)
Displacement: 1.5L | Power: 103 hp | Torque: 101 lb-ft | Engine Code: 1NZ-FE | Config: Inline-4, DOHC | Production: 2004–2006
The first-generation xB shared the same 1NZ-FE 1.5-litre engine as the xA. Compact, reliable, and fuel-efficient, this engine powered one of the most recognisable cars of the 2000s — the boxy, cube-shaped xB that became a cult icon in American car culture. If you're keeping a first-gen xB on the road, a used Scion xB engine from our inventory is one of the most cost-effective replacements available.
Scion xB Engine — Second Gen (2008–2015)
Displacement: 2.4L | Power: 158 hp | Torque: 162 lb-ft | Engine Code: 2AZ-FE | Config: Inline-4, DOHC | Production: 2008–2015
The second-generation xB received a significant upgrade, switching to Toyota's 2.4-litre 2AZ-FE four-cylinder engine producing 158 hp and 162 lb-ft of torque. This engine also appears in the Toyota Camry and RAV4, making it one of the most well-supported and widely available used Toyota-family engines on the market. A used Scion xB 2AZ-FE engine is a popular replacement for second-gen xB owners, with excellent parts availability and proven long-term reliability.
Scion tC Engine — First Gen (2005–2010)
Displacement: 2.4L | Power: 161 hp | Torque: 163 lb-ft | Engine Code: 2AZ-FE | Config: Inline-4, DOHC | Production: 2005–2010
The first-generation Scion tC used the same 2AZ-FE 2.4-litre engine that powered the second-gen xB, producing 161 hp and 163 lb-ft of torque. Paired with either a five-speed manual or a four-speed automatic, the tC was Scion's sporty coupe offering — and the 2AZ-FE gave it enough grunt to be genuinely enjoyable to drive. A used Scion tC engine in 2AZ-FE spec is one of our most frequently requested units, with strong supply from our nationwide salvage network.
Scion tC Engine — Second Gen (2011–2016)
Displacement: 2.5L | Power: 179 hp | Torque: 173 lb-ft | Engine Code: 2AR-FE | Config: Inline-4, DOHC | Production: 2011–2016
The second-generation tC was upgraded to Toyota's 2.5-litre 2AR-FE engine, producing 179 hp and 173 lb-ft of torque. This was a meaningful improvement over the first generation and made the second-gen tC one of the quickest front-wheel drive cars in its class. The 2AR-FE is a robust engine, though timing chain wear can become an issue on higher-mileage examples — which is often why owners seek a used Scion tC 2AR-FE engine replacement rather than attempting a repair.
Scion xD Engine (2008–2014)
Displacement: 1.8L | Power: 128 hp | Torque: 125 lb-ft | Engine Code: 2ZR-FE | Config: Inline-4, DOHC | Production: 2008–2014
The Scion xD used Toyota's 2ZR-FE 1.8-litre four-cylinder engine, producing 128 hp and 125 lb-ft of torque. Compact and fuel-efficient, the xD was positioned as a slightly more grown-up alternative to the xA, with a longer wheelbase and more interior space. The 2ZR-FE is a reliable unit that shares its architecture with the Toyota Corolla. A used Scion xD engine is a well-priced, easy-to-source replacement for xD owners.
Scion iQ Engine (2012–2015)
Displacement: 1.3L | Power: 94 hp | Torque: 89 lb-ft | Engine Code: 1KR-FE | Config: Inline-3, DOHC | Production: 2012–2015
The Scion iQ was a micro city car built around Toyota's tiny 1KR-FE 1.3-litre three-cylinder engine producing 94 hp and 89 lb-ft of torque. It was never designed to be fast — it was designed to be the smallest, most manoeuvrable car on sale in America. The 1KR-FE is a unique engine not shared with many other models, which makes sourcing a used Scion iQ engine slightly more specialist — but we carry stock from our nationwide network of over 500 salvage partners.
Scion FR-S Engine (2013–2016)
Displacement: 2.0L | Power: 200 hp | Torque: 151 lb-ft | Engine Code: FA20D | Config: Boxer-4, DOHC | Production: 2013–2016
The FA20D is the most sought-after engine in Scion's history. Co-developed with Subaru, this 2.0-litre horizontally-opposed (boxer) four-cylinder engine produced 200 hp and 151 lb-ft of torque. What made it special wasn't peak power — it was the engine's high-revving character, low centre of gravity, and the way it paired with the FR-S's perfectly balanced rear-wheel drive chassis. The FA20D redefined what an affordable sports car could be. A used Scion FR-S engine is one of the most in-demand units we carry, sought by FR-S owners and engine swap enthusiasts alike.
Scion iA Engine (2016)
Displacement: 1.5L | Power: 106 hp | Torque: 103 lb-ft | Engine Code: P5-VPS | Config: Inline-4, SkyActiv | Production: 2016
The Scion iA was actually built by Mazda — it was a rebadged Mazda2 sedan fitted with Mazda's 1.5-litre SkyActiv-G engine producing 106 hp and 103 lb-ft of torque. Offered for just one model year before Scion's discontinuation, the iA was well-regarded for its fuel efficiency and driving dynamics. A used Scion iA engine uses Mazda's SkyActiv architecture — a modern, clean-burning unit with a strong reliability record.
Scion iM Engine (2016)
Displacement: 1.8L | Power: 137 hp | Torque: 126 lb-ft | Engine Code: 2ZR-FAE | Config: Inline-4, DOHC | Production: 2016
The Scion iM was a Toyota Corolla-based hatchback fitted with the 2ZR-FAE 1.8-litre Valvematic engine producing 137 hp and 126 lb-ft of torque. Like the iA, it was sold for just one year before being absorbed into the Toyota lineup as the Corolla iM. The 2ZR-FAE is shared with multiple Toyota models, making parts widely available. A used Scion iM engine is a practical, well-supported replacement for iM owners.
Common Reasons Scion Engines Need Replacing
Scion vehicles use Toyota and Mazda-sourced engines — generally very reliable — but like any engine, specific issues can develop as mileage climbs. Here are the most common reasons owners search for a used Scion engine replacement:
Timing Chain Wear (2AR-FE — tC Second Gen) — The 2AR-FE engine used in the second-generation tC is known to develop timing chain stretch and tensioner wear at higher mileages, causing rattling on cold startup and in severe cases, engine failure. Many tC owners find a used engine replacement more cost-effective than a timing chain repair on a worn unit.
Oil Consumption (FA20D — FR-S) — The FA20D boxer engine in the FR-S has a documented history of excessive oil consumption on some units, particularly earlier production years. Regular oil level checks are essential. When oil consumption becomes severe, a used engine replacement is often the cleanest solution.
Head Gasket Failure (2AZ-FE — xB, tC First Gen) — The 2AZ-FE has a known weakness with head gasket failures, particularly when the cooling system has not been maintained. This is one of the most common reasons first-gen tC and second-gen xB owners seek a used Scion tC engine or used Scion xB engine replacement.
Water Pump and Cooling System Failures — Across multiple Scion models, water pump failure leading to overheating is a recurring issue on higher-mileage vehicles. Catching this early prevents serious damage — but when overheating has already occurred, an engine replacement is often unavoidable.
Carbon Buildup on Intake Valves (2ZR-FE / 2ZR-FAE) — The direct and Valvematic injection engines in the xD and iM can develop carbon deposits on intake valves over time, reducing efficiency and power output.

Frequently Asked Questions — Used Scion Engines
How long does a used Scion engine last?
A low-mileage, properly inspected used Scion engine can last 100,000 to 150,000+ additional miles when installed correctly and maintained with regular oil changes and coolant services. Scion vehicles use Toyota-engineered engines — some of the most durable powerplants ever mass-produced — so a quality used unit has genuine longevity ahead of it when properly cared for.
Are Scion engines the same as Toyota engines?
In most cases, yes. The majority of Scion engines are shared directly with Toyota models — the 1NZ-FE (xA, first-gen xB) appears in the Toyota Echo and Yaris, the 2AZ-FE (xB second gen, tC first gen) is shared with the Camry and RAV4, and the 2ZR-FE (xD, iM) comes from the Corolla family. The only exception is the iA, which used a Mazda SkyActiv engine, and the FR-S, which co-developed the FA20D boxer engine with Subaru. This means parts are widely available and mechanics are familiar with these engines — a big advantage when buying a used Scion engine for sale.
Is it worth repairing a Scion engine or replacing it with a used one?
For common issues like head gasket failure, timing chain wear, or turbo damage on a high-mileage Scion, replacing the engine with a quality used Scion engine is often more cost-effective than repairing the existing one. You get a lower-mileage unit with a fresh warranty at a fraction of the cost of a full engine rebuild. Our team can help you assess which option makes more sense for your specific vehicle.
What is the best Scion engine ever made?
The FA20D boxer engine from the Scion FR-S is widely regarded as the greatest engine Scion ever offered. Developed jointly with Subaru, it produced 200 hp from a 2.0-litre naturally aspirated flat-four — and its high-revving, free-breathing character made the FR-S one of the most exciting affordable sports cars of its generation. It remains one of the most requested used Scion FR-S engines in our inventory.
Do you carry used engines for discontinued Scion models like the xA, xB, and tC?
Yes — we carry used Scion engines for every model in the lineup including the xA, xB (both generations), xD, tC (both generations), iQ, iA, iM, and FR-S. Because Scion vehicles share engines with Toyota and Mazda models, supply from our 500+ nationwide salvage partners is strong across all model years.
How do I find the right used Scion engine for my vehicle?
The most reliable method is to match by VIN number — your Vehicle Identification Number confirms the exact engine code and specification your Scion was built with. Use our AI-powered search tool on the website, or call our team at +1 (888) 618-8881 and we'll match you to the correct engine fast.
What warranty comes with a used Scion engine from Turbo Auto Parts?
Every used Scion engine for sale at Turbo Auto Parts includes a 3-year or 30,000-mile warranty — whichever comes first — plus a 100% 15-day money-back guarantee. Full terms are available on our Warranty page.
