1. Jasper Engines & Transmissions Remanufactured 2.3L Ford EcoBoost Crate Engine: Best Overall
In our evaluation, the Jasper 2.3L EcoBoost stands out as the best overall 4 cylinder crate engine. It delivers factory-correct performance with the added reliability of remanufacturing. Owners report smooth installation and impressive power gains over stock. The included turbo and fuel system simplify the swap, making it a turnkey solution for Ford enthusiasts.
However, this engine commands a premium price. It is not the best choice for budget builds or for those who want to build an engine from scratch. Consider this if you prioritize reliability and a strong warranty over upfront cost.
- Remanufactured to OEM specs with upgraded components for reliability
- Includes turbocharger, fuel injectors, and intake manifold
- Backed by a 3-year/100,000-mile warranty
Pros: Excellent power and torque for a 4 cylinder; Comprehensive warranty gives peace of mind
Cons: Higher price point than some competitors
2. GM Genuine Parts 2.4L Ecotec Crate Engine: Best Value
For budget-conscious builders, the GM 2.4L Ecotec offers excellent value. It is a new engine from GM, ensuring consistent quality and fitment. We compared its specs and owner feedback, and it consistently earns high marks for reliability. The engine comes with essential components, reducing the need for extra parts.
Its naturally aspirated design limits power potential. If you need more than 200 hp or plan to boost it, this engine may not suit your goals. It is ideal for daily drivers or restoration projects where reliability and cost are priorities.
- Genuine GM new engine, not remanufactured
- Compatible with many GM cars (Cobalt, HHR, etc.)
- Includes front cover, oil pan, valve cover, and timing chain
Pros: Affordable for a brand-new crate engine; Simple installation with basic tools
Cons: Moderate power output, not for high-performance builds
3. ATK High Performance 2.0L VW/Audi Turbo Crate Engine: Best for Tuners
Tuners looking for a robust platform will appreciate the ATK 2.0L. Its forged internals and ported head allow for significant power increases. Based on owner feedback, this engine responds well to larger turbos and aftermarket engine management. It is a favorite among VW/Audi enthusiasts for high-horsepower builds.
However, this engine is not a plug-and-play solution. It often requires a standalone ECU, custom intercooler piping, and professional tuning. If you are not comfortable with advanced engine management or want a simple swap, this engine may be more than you need.
- Forged pistons and rods for high boost applications
- Includes ported cylinder head and ARP hardware
- Designed for VW/Audi 1.8T/2.0T swaps
Pros: Built to handle substantial power upgrades; High-quality components from reputable manufacturer
Cons: May require custom tuning and additional parts
4. Ford Performance 2.3L Duratec Crate Engine: Best for Mazda/Ford Swaps
The Ford Performance 2.3L Duratec is a solid choice for those swapping into Mazda Miatas or older Ford vehicles. We researched its compatibility and found it to be one of the easiest swaps due to its size and mounting points. Owner feedback highlights its durability and smooth operation. The included manifolds simplify the installation process.
Its modest power output may disappoint those seeking performance. It is best suited for mild street builds or off-road applications where torque and reliability matter more than peak horsepower. For forced induction, you would need to add a turbo kit.
- New OEM engine from Ford Performance
- Common swap for Mazda Miata, Ford Ranger, and Focus
- Includes intake manifold, exhaust manifold, and ignition system
Pros: Reliable and well-documented swap; Good parts availability and aftermarket support
Cons: Lower power output compared to turbo options
5. Mopar 2.0L Turbo Crate Engine (Jeep Wrangler): Best for Wrangler
Jeep owners looking for a direct replacement or upgrade for their Wrangler JL will find this Mopar crate engine appealing. It delivers the same power and torque as the factory engine, with all necessary sensors and harness included. Based on owner feedback, it installs cleanly and performs well both on and off road.
However, this engine is pricey and not suitable for non-Jeep swaps. It also has known issues with carbon buildup on intake valves due to direct injection, which may require periodic cleaning. If you do not own a JL Wrangler, skip this engine.
- Factory engine for 2018+ Jeep Wrangler JL
- Direct injection and turbo for efficiency and power
- Includes engine wiring harness and sensors
Pros: Strong low-end torque ideal for off-roading; Direct OEM replacement for JL Wranglers
Cons: Expensive and limited to specific applications
6. Honda K24A2 Crate Engine (JDM): Best for Honda Tuners
The JDM K24A2 is a favorite among Honda enthusiasts for its high-revving nature and upgrade potential. We researched owner feedback and found that it offers great value for those willing to do a custom swap. The engine is often sold with low mileage and includes many accessories, simplifying the build.
However, as a used import, its condition can vary. There is risk of wear or hidden damage. Additionally, the wiring and ECU integration can be complex. This engine is not for beginners or those seeking a plug-and-play solution. It is best for experienced DIYers who want a strong foundation for a high-horsepower build.
- JDM import engine, popular for K-swaps
- High-revving VTEC with good aftermarket support
- Includes intake manifold, throttle body, and alternator
Pros: Excellent power per dollar for Honda swaps; Large aftermarket for performance parts
Cons: Used engine with unknown history; May require wiring harness modifications
7. Chevrolet Performance 2.0L LSJ Supercharged Crate Engine: Best Supercharged Option
The Chevrolet Performance LSJ is a blast from the past for fans of the Cobalt SS. It comes with a factory supercharger and intercooler, providing instant throttle response. In our evaluation, it offers a fun driving experience for a classic GM platform. Owner feedback often praises its torque and unique sound.
However, this engine is discontinued and parts are becoming scarce. The supercharger can be problematic if not maintained, and the engine’s durability is not on par with newer designs. It is not recommended for daily driver reliability. Only consider this if you are building a dedicated project car and enjoy working with older GM components.
- Factory supercharged engine from Chevrolet Cobalt SS
- Includes supercharger, intercooler, and fuel system
- Known for strong mid-range torque
Pros: Unique supercharged power delivery; Complete system with supercharger included
Cons: Aging design with limited parts availability; Not as durable as modern turbo engines

How do I choose the right 4 cylinder crate engine for my car?

Our guide compares popular options to help narrow your choice.
Can I install a 4 cylinder crate engine myself?
