What Is a Crate Engine?

A crate engine is a complete engine assembly that ships in a crate, ready to drop into your vehicle. It can be brand new, remanufactured, or a tested used unit, depending on what the seller offers.

If you're shopping for a replacement engine, you'll see three main options: crate engines, remanufactured engines, and used or JDM engines. Each one fits a different budget and goal. This guide breaks down what each term means, how they compare, and how to pick the right one for your car.

Crate Engine, Defined

The term "crate engine" comes from how the engine is packaged and shipped. It arrives on a pallet or in a wooden crate, fully assembled and ready for installation.

A crate engine can fall into a few categories:

• Brand new crate engine. Built from all-new parts, often by the original manufacturer or a trusted engine builder. No prior use, no wear.
• Remanufactured crate engine. Built around a core (used engine block), with worn parts replaced or machined to spec. Tested before it ships.
• Used or JDM crate engine. A running engine pulled from another vehicle, often imported from Japan. Tested for compression and leaks, but not rebuilt.

All three ship as a complete long block or full engine, ready to bolt in. That's what makes them "crate" engines.

If you want a deeper look at what's actually inside the box, our upcoming post on Long Block vs Short Block breaks down exactly which parts are included and which ones you'll need to source yourself.

Brand new crate engines are a good fit if you want zero history and the longest expected lifespan. Toyota and other manufacturers offer these for popular models. Our Camry 2AR-FE and Tacoma 1GR-FE brand-new engine listings are examples of this option.

Crate vs Remanufactured vs Used: Comparison Table

Here's a quick side-by-side look at how these three options stack up.

This table gives you a starting point. Your final choice depends on your budget, how long you plan to keep the vehicle, and how easy the engine is to find for your specific model.

Pros and Cons of a Crate Engine

Crate engines have clear upsides, but they're not perfect for every situation. Here's a simple breakdown.

Pros:

• Ready to install as a complete unit
• No guesswork about what's inside
• Often comes with a warranty
• Saves time compared to rebuilding your own engine

Cons:

• Higher upfront cost than buying individual parts
• You may pay a core charge if you don't return your old engine
• Some accessories (alternator, intake, etc.) may not be included
• Shipping a full engine costs more than shipping smaller parts

Before you buy, always check the parts list. Some crate engines include the oil pan, intake manifold, and accessories. Others only include the long block. Knowing this ahead of time avoids surprise costs later.

Example: The Toyota 22RE Crate Engine

The Toyota 22RE is one of the most popular crate engine searches, and for good reason. It's a reliable four-cylinder engine used in older Toyota trucks and 4Runners.

A 22RE crate engine typically comes as a long block. That means the block, crankshaft, pistons, rods, and cylinder head are assembled and ready to go. You'll still need to transfer over your accessories, like the alternator, starter, and intake.

If you're replacing the engine in a 4Runner, check out our 4Runner 22R-E engine product page to see exactly what's included and how it's packaged.

The 22RE is also a good example of how crate engines bridge the gap between new and used options. You can find brand new long blocks, remanufactured units, or tested JDM 22RE engines, depending on your budget.

How to Choose the Right Engine

Picking between a crate, remanufactured, or used engine comes down to a few practical factors.

• Budget. New crate engines cost the most. Used JDM engines cost the least. Remanufactured engines sit in the middle.
• Mileage and condition. If you want zero miles on the engine, a new crate engine is your only true option. Remanufactured engines are also rebuilt to like-new condition. JDM engines vary, but reputable sellers test compression and check for leaks before listing them.
• Warranty. New crate engines usually carry the longest warranty. Remanufactured engines often come with a shop warranty. Used engines have shorter or limited warranties, so always ask before buying.
• Availability. Not every engine is available brand new. Older or less common engines, like many JDM swaps, are easier to find used. If you're working on an older vehicle, browse our JDM Engines collection to see what's currently in stock.
• Your goals for the vehicle. If you're keeping the car for years, a new or remanufactured engine makes sense. If it's a budget fix or a project build, a used engine can be the smarter choice.

Once you know your budget and goals, the comparison table above can help you narrow down the right type quickly.

Worth Knowing Before You Buy

Whichever option you choose, a few things apply across the board.

• Core charges. Some remanufactured engines require you to send back your old engine (the core). If you don't, you'll pay an extra fee. Ask about this before you order.
• Break-in period. New and remanufactured engines need a break-in period. This means following specific instructions for the first few hundred miles, like avoiding hard acceleration and changing the oil early.
• Matching specs. Always confirm the engine matches your vehicle's year, trim, and transmission type. Even small differences in engine codes can cause fitment issues.
• Shipping and handling. A full engine is heavy. Factor in shipping costs and make sure someone is available to help unload it.

If you're also weighing whether to rebuild your current engine instead of replacing it, our upcoming guide on Rebuilt vs Remanufactured vs Used covers that comparison in detail.

FAQs

Is a crate engine brand new?

Not always. A crate engine can be brand new, remanufactured, or a tested used unit. The term refers to how it's packaged and shipped, not its condition.

What's the difference between a crate engine and a long block?

A long block is the core assembly: block, crankshaft, pistons, and cylinder head. A crate engine is often sold as a long block, but it may also include extra parts depending on the seller.

Do crate engines come with a warranty?

Most do, but the length and coverage vary. Brand new crate engines usually have the longest warranty. Remanufactured and used engines typically come with shorter, shop-backed warranties.

Are crate engines worth it?

For most buyers, yes. They save time over building your own engine and reduce the risk of unknown issues, especially compared to buying a used engine with no testing history.

What's included with a 22RE crate engine?

Most 22RE crate engines ship as a long block, including the block, head, crankshaft, pistons, and rods. Accessories like the alternator and intake usually need to be transferred from your old engine.
