When people come to us asking for a Defender, one of the first questions we ask is: how do you want it to drive? Choosing the right engine is about more than horsepower or fuel type. It shapes the entire personality of your build. Whether you're after the quiet punch of electric power or the unmistakable growl of a V8, your engine choice defines how your Defender feels to drive, how it sounds, and how it performs day to day.

At Shoreline, we offer a range of powertrains tailored to different driving styles and philosophies. Each one has its place — and over the years, we’ve worked with just about every option out there. Here's what we've learned.

LS3 6.2L V8 – Power and Performance

The LS3 6.2L V8 produces approximately 430 horsepower and 425 lb-ft of torque, significantly enhancing the Defender's power and performance. Known for its reliability, compact design, and robust output, this engine transforms the Defender into a high-performance machine with 0–60 mph times in the 5–6 second range. It delivers smooth highway cruising and strong overtaking capabilities. Paired with a modern automatic transmission, the LS3 ensures comfort both on and off-road. Drivers appreciate its refined handling, immediate throttle response, and commanding presence on the road, making it one of the most popular choices for modern Defender builds.

GM 5.7L V8 – Classic American Muscle

The GM 5.7L V8 engine produces around 255–300 horsepower and up to 330 lb-ft of torque, integrating classic American muscle with the Defender’s rugged charm. Known for its durability and ample low-end torque, this engine provides strong pulling power and a responsive throttle feel. Its simplicity and distinctive exhaust note deliver a deeply mechanical driving experience, ideal for those who value traditional V8 responsiveness and an analog connection to their vehicle.

Ford 2.3L EcoBoost – Modern Efficiency

The Ford 2.3L EcoBoost delivers around 300 horsepower and 310 lb-ft of torque, transforming the Defender into a lighter, more agile vehicle with impressive acceleration. 0–60 mph can be achieved in under 7 seconds depending on build configuration. Its turbocharged design combines fuel savings with strong mid-range performance. This engine offers a responsive throttle, improved fuel economy, and a balanced driving experience, making it ideal for urban daily drivers and nimble Defender 90 builds.

300 TDi – Reliable Workhorse

The 300 TDi produces approximately 122 horsepower and 195 lb-ft of torque, known for its durability, simple mechanics, and proven performance off-road. Though it’s not built for speed, its steady torque makes it excellent for towing and technical trail use. With 0–60 mph times around 17–18 seconds, it’s far from quick, but its reliability and ease of service in harsh conditions make it one of the most trusted engines for long-distance, off-grid overlanding.

200 TDi – Classic Durability

The 200 TDi generates around 111 horsepower and 188 lb-ft of torque. It may not be quick, with a 0–60 mph time close to 18–20 seconds, but it makes up for it with mechanical resilience. Perfect for period-correct restorations or basic expedition builds, it’s praised for its ability to keep running in harsh environments and its ease of repair with minimal tools or electronics.

TD5 – Tunable and Versatile

The TD5 engine produces around 122 horsepower and 221 lb-ft of torque in standard form, but can be tuned to deliver up to 180+ horsepower and 300 lb-ft of torque. With the right turbo upgrade, intercooler, remap, and exhaust enhancements, some builds can exceed 200 horsepower while retaining diesel reliability. Modern ECU management allows fine-tuned power delivery, throttle mapping, and drivability adjustments, giving the TD5 an edge in both versatility and responsiveness. It’s one of the most upgrade-friendly engines available for a Defender. 0–60 mph times can improve to under 10 seconds with performance mapping. This makes the TD5 ideal for those seeking a blend of everyday usability, tuning potential, and diesel reliability.

EV Options – Sustainable Innovation

Electric conversions deliver instant torque and whisper-quiet operation. Hyper9-based systems typically produce around 120 horsepower and 173 lb-ft of torque with 0–60 mph in the 12-second range and an average range of 100–120 miles. Tesla Model 3 drive unit conversions offer up to 300 horsepower and 310 lb-ft of torque, achieving 0–60 mph in as little as 5 seconds. These builds often deliver 250–300 miles of real-world range and support fast charging times as quick as 40 minutes. The motor is mounted mid-vehicle, with battery packs positioned in the engine bay and under the floor, maximizing space and balance. These systems bring modern-day responsiveness and simplicity to classic Defenders, redefining what daily usability looks like while reducing maintenance and emissions.

Choosing an engine isn’t just about performance figures. It’s about feel, history, and lifestyle. Whether you’re after a rumbling V8, a diesel icon, or a future-proof EV, we’ll help you find the powertrain that fits your Defender — and your story.
