Most engine listings assume you already know what you need
If your engine has failed, the first problem is not finding a supplier. It is that almost every used-engine listing is organised by engine code, and you have a car, not a code. Searching for “Camry engine” returns three different engines, and picking the wrong one is an expensive mistake to make from a photograph.
So this site is organised the other way round. Start from your vehicle, and the engine code comes out the other end. If you already know the code, start from the engine instead. Both routes end at the same availability check.
What we do and what we do not
This site identifies the right engine for your vehicle and checks availability and pricing with suppliers. It does not hold inventory, and it does not publish prices, because engine pricing depends on the variant, the condition, what is included and how it reaches you. A published range would be wrong for most people reading it.
What you get instead is a quote for a specific engine that has been checked against your specific vehicle, and, if the honest answer is that the engine is hard to source or the car is not worth the work, you get that instead. How this site is paid is set out plainly.
Why engine codes matter
The same model year can use completely different engines depending on the trim, transmission and market. A 2008 Honda Civic is either an R18A1 or a K20Z3, depending entirely on whether it is an Si. Ordering by year alone is the single most common way a Japanese engine order goes wrong.
Engine codes tell you the specific variant: displacement, head design, compression ratio, and the parts that interchange with it. When you request an engine with the code, or when you provide the year, make, model and trim so we can identify it, you avoid the wrong engine and the return shipping that follows.
Find your engine
Year, make, model and trim is enough to start. Everything else is optional, including the engine code, which most people do not have.

Commonly requested engine codes
The families that come up most in Valley replacement work. All engine families.
- K24HondaThe 2.4-litre K-series four fitted to the Accord, CR-V, Element and TSX, and the most commonly requested Honda replacement engine in the Valley.
- 2AZ-FEToyotaThe 2.4-litre four from the Camry, RAV4, Highlander and Scion tC: high-volume, widely available, and the Toyota replacement engine Phoenix asks about most.
- VQ35DENissanNissan’s 3.5-litre V6: fitted to the Altima, Maxima, Murano, Pathfinder, Quest and 350Z, and across the Infiniti range. One of the most widely available used V6s in Phoenix.
- EJ25SubaruSubaru’s 2.5-litre boxer from the Forester, Outback, Legacy and Impreza: the engine behind Phoenix’s most common Subaru replacement question, head gaskets included.
- J35HondaThe 3.5-litre Honda V6 fitted to the Odyssey, Pilot, Ridgeline and Accord V6: the family’s workhorse six and a common replacement on high-mileage minivans.
- 2JZToyotaToyota’s 3.0-litre inline-six from the Supra, Aristo and GS300: the most requested JDM engine by name, and the one where verifying what you are actually buying matters most.
Start from your vehicle instead
Each page breaks the model down by generation and trim, so you can find the engine code without going near a parts catalogue. All vehicles.
- Honda CivicThe Civic spans three engine families across the generations people still replace engines in, and the trim decides which one.
- Toyota CamryFour-cylinder Camrys from 2002 to 2011 are 2AZ-FE: an engine with two known failure modes worth understanding before you buy a used one.
- Nissan AltimaFour-cylinder and V6 Altimas use the QR25DE and VQ35DE respectively, and on many of them the transmission deserves checking before the engine.
- Subaru ForesterNaturally aspirated Foresters use the EJ25 and turbocharged XT models the EJ255, and head gaskets are why most owners are reading this.
Beyond the engine itself
An engine on a pallet is not a running car. Three things usually come up alongside it, and each has its own page because each has its own answer.
- Transmissions. When they are quoted with the engine and when they are separate, plus the CVT question that decides a lot of Nissan jobs.
- Installation. What belongs in the quote, what should be replaced while the engine is out, and how to judge a shop.
- Engine swaps. How a swap differs from a replacement, and what it commits you to under Arizona emissions testing.
On the Arizona question specifically, we say what the state actually publishes and where it stops. What Arizona tests, and what ADEQ does not publish about engine swaps.
Engine compatibility and fitment
A JDM engine purchase involves several compatibility considerations beyond the basic engine code. The engine that left the factory in a similar vehicle may not be a direct replacement for yours.
What to check before ordering
- Engine code matching: The code must match or be a known compatible variant for your specific year, make, model and trim.
- Transmission compatibility: The engine must mate with your transmission bellhousing. Transmission type can affect compatibility and the parts required for installation.
- ECU and immobiliser: JDM engines may have different engine control units and immobiliser systems. Your existing ECU may not communicate with a JDM engine without modification.
- Wiring harness: The engine harness plug connections and sensor layouts can vary between markets. A JDM harness may not connect directly to your chassis harness.
- Intake and exhaust: Intake manifolds, throttle body orientation, and exhaust header flanges can differ. These may need to be swapped or adapted.
- Accessories and mounts: Alternator, power steering, air conditioning compressor, and engine mount positions can vary between JDM and USDM versions.
Replacement vs. engine swap
A direct replacement uses an engine that was originally available in your vehicle's market and is designed to bolt in with minimal modification. An engine swap involves installing an engine that was not originally offered, which requires additional fabrication, wiring work, and often emissions complications in Arizona.
This site focuses on direct replacements. If you are planning a swap, be explicit about it in your request so the supplier can advise on compatibility rather than assume a replacement.
What JDM means and what to expect
JDM stands for Japanese Domestic Market: engines originally built for and sold in Japan, then imported after being removed from donor vehicles. It is a statement about where the engine came from, not a quality grade.
Why buyers look for JDM engines
Japanese engines are imported from donor vehicles in Japan. Buyers look for JDM engines for various reasons, including access to specific engine variants not available in the US market, engines from vehicles with lower reported mileage, or performance-oriented versions of common engines.
What to verify before purchasing
- Compression test results: Ask for compression readings across all cylinders. Consistent compression within manufacturer specifications is a key indicator of engine health.
- Leak-down test: This can reveal issues with valves, rings, or head gaskets that a compression test alone might miss.
- Visual inspection: Look for oil leaks, damaged sensors, broken accessories, and evidence of overheating (discolored heads, warped components).
- What is included: Confirm whether the engine comes as a long block (block, heads, internals only) or complete (intake manifold, exhaust manifolds, accessories, etc.).
- Warranty terms: Understand what warranty is offered and what it covers. Warranty coverage varies by supplier and engine, so confirm the applicable terms before purchasing.

How the engine request process works
The process is designed to identify the correct engine before any commitment is made, avoiding the wrong engine and the complications that follow.
- Provide vehicle details: Year, make, model, and trim are enough to identify most engines. The engine code field is optional because most buyers do not know it, but including it when you have it speeds up the process.
- Engine identification: We verify which engine your vehicle actually takes using factory application data. If you provided an engine code, we cross-check it against your vehicle to confirm compatibility.
- Availability check: We check current availability for your specific engine with suppliers. Stock moves constantly, so this is done in real time rather than from a static inventory list.
- Quote and options: You receive availability information and pricing for the available options. The quote reflects the specific engine, its condition, what is included, and how it will reach you.
- Compatibility confirmation: Before any commitment, the supplier confirms fitment for your specific vehicle. If there are compatibility concerns, you are told rather than shipped an engine that may not work.

Common questions
What information do I need to request a JDM engine?
Year, make, model, and trim are enough to identify most engines. The engine code is optional because most buyers do not know it, but including it when you have it speeds up the process. Your VIN can also help remove any remaining doubt. Transmission type (automatic or manual) is useful because it can affect engine compatibility.
How do I find my engine code?
Engine codes are typically found on the engine block itself, often on a machined pad near the cylinder head or on the timing belt cover. Your vehicle documentation, owner manual, or parts catalog may also list it. If you cannot find it, provide the year, make, model, and trim and we can identify the engine from factory application data.
Do JDM engines fit US vehicles automatically?
No. Factory fitment is not the same as compatibility. While a JDM engine may have been used in a similar vehicle in Japan, differences in ECU, wiring harness, transmission bellhousing, intake/exhaust configuration, and emissions equipment can affect fitment. Always verify compatibility before purchasing, especially for emissions-controlled states like Arizona.
Can I request a specific engine code?
Yes. If you know the specific engine code you need, include it in your request. We will cross-check it against your vehicle to confirm compatibility and check availability for that exact variant. This is particularly useful for performance builds or when you are replacing an engine with a specific JDM variant.
What is included with a JDM engine?
What is included varies by supplier and engine. Some engines come as long blocks (block, heads, and internals only), while others are more complete and may include intake manifolds, exhaust manifolds, accessories, and wiring. The quote will specify exactly what is included so you can plan for any additional parts you may need.
Do you ship engines to Phoenix?
Shipping and pickup options depend on the specific engine and supplier. When you request an engine, the available fulfillment options for your location will be provided in the quote.
How do I request current availability?
Use the Engine Finder on this page to submit your vehicle details. The request identifies the correct engine for your vehicle and checks availability and pricing options.
What should I verify before ordering an engine?
Verify the engine code matches your vehicle, confirm compatibility with your transmission and ECU, and understand what is included with the engine. Ask about the engine condition, mileage, and any available testing results.
What is the difference between a replacement engine and an engine swap?
A replacement engine is one that was originally offered in your vehicle market and is designed to bolt in with minimal modification. An engine swap involves installing an engine that was not originally offered, which requires additional fabrication, wiring work, and often emissions complications. Replacements are generally more straightforward and maintain emissions compliance more easily.
Which parts of the Phoenix area do you cover?
Phoenix, Mesa, Chandler, Scottsdale, Glendale, Gilbert, Tempe, Peoria, Surprise, Avondale, Goodyear, Buckeye, Queen Creek and Apache Junction: effectively the whole Valley. Delivery and collection arrangements are confirmed per order rather than assumed.
