The Jimny is a compact 4×4 vehicle already known for its ruggedness and reliability.
However, if you seek more power and performance, upgrading the standard M13A VVT motor to a more powerful M15A, M16A, or M18A motor can be an excellent option.
This blog post will guide you through the process, highlighting the key considerations and steps involved.
Choosing the Right Motor
When considering an upgrade, it’s important to note that all three motors – the M15A, M16A, and M18A – bolt straight up to the gearbox bell housing and engine mount brackets. This means they can be fitted directly into your JB43 M13A VVT Jimny without any major modifications.
- Important Note for Jimny Owners: If you’re contemplating an upgrade with the M16A Swift Sport engine (models from 2012 and later), it’s crucial to know that the crank sensor wheel differs from your Jimny’s original part. To guarantee a perfect fit with your Jimny’s crank angle sensor and ECU, a swap is necessary. Additionally, be aware that the water outlet located at the back of the cylinder head doesn’t match the shape of the one on the Jimny. This information is vital for ensuring a successful engine upgrade.
Upgrading the motor of a Jimny can significantly enhance its performance, but finding a suitable second-hand motor can be challenging. Here are some key points to consider:
- High Mileage: Be wary of engines with high kilometres, as they may have significant wear and tear.
- Oil Leaks: Check for any signs of oil leaks, which could indicate poor maintenance or potential failure points.
- Sludge Build-up: Inspect the rocker cover for sludge build-up, as this can indicate lack of maintenance affecting the engine’s efficiency and longevity.
- Head Gasket Failure: These motor use a multi layer steel head gasket and it is not un-common to being showing signs of failure at this age.

Preparing the Second-hand Motor
Before installing the second-hand motor, there are several components that need to be replaced:
- Oil Filter Housing: The existing oil filter housing needs to be removed as if fouls on the chassis rail and replaced with a new standpipe tube for the filter to screw directly onto.
- Sump and Oil Pickup: These need to be replaced with the Jimny ones off your original M13A motor to ensure proper clearance on the front diff housing.
- Front & Rear Oil Seals: We recommend replacing these before installing the new motor to prevent any potential oil leaks, especially onto a new Exedy Heavy Duty clutch.
- Water Pump: A new water pump is a must for ensuring optimal cooling efficiency.
- Radiator: A new radiator will ensuring optimal cooling efficiency.
- Cooling Hoses: It’s strongly recommended to replace all cooling hoses as part of the upgrade, to ensure longevity of the motor upgrade.
Rebuilding your Motor
Given the age of the motors, they often require a freshen up or even a complete total rebuild. Over time, engine components can wear out and performance can degrade, making it necessary to overhaul the motor.
- Cylinder Head: Reconditioning the cylinder head is a vital part of ensuring the longevity of your new motor. This process typically involves cleaning, inspecting for cracks, resurfacing for proper sealing, and valve jobs to ensure optimal airflow.
- Internal Parts: Refreshing or rebuilding a motor often involves replacing key internal parts. It’s common to install new pistons, rings, bearings, gaskets, seals, and timing chains. These new components can significantly improve the performance and reliability of the motor.
- Reboring: For motors with severely worn bores, reboring is required. This process involves enlarging the cylinder bore size and fitting oversized pistons and rings. Reboring can restore the engine’s power and efficiency, making it an essential step for engines with significant wear.
Remember, each of these steps is critical to ensuring that your upgraded Jimny motor performs at its best and lasts for many more adventures. Always consider consulting with a professional 4WD mechanic to achieve the best results for your motor upgrade.
Always ensure that you source parts from reputable Suzuki parts suppliers and consider consulting with a professional mechanic to achieve the best results for your Jimny motor upgrade. Remember, a well-maintained engine can provide better reliability and performance.
Power to the Ground
The Dakin Exedy heavy duty clutch kit is a high-performance upgrade designed to handle increased horsepower and torque. It’s an excellent choice for vehicles like the Jimny, often used in demanding off-road or towing situations.
The Exedy brand clutch kit is designed to provide a smooth, yet firm engagement, allowing for maximum power transfer from the engine to the wheels. The heavy-duty construction ensures durability and longevity, even under harsh driving conditions.
In addition to upgrading the clutch, it’s also a good idea to replace the cable clutch in Jimnys. Over time, a Jimny’s clutch cable can start to seize up, making the pedal feel very heavy. This also affects the overall driving experience. Replacing the clutch cable can result in a smoother pedal feel, making the vehicle more enjoyable to drive.
Final Thoughts
Upgrading your Suzuki Jimny’s motor can significantly enhance its performance and driving experience. However, it’s important to carefully consider the requirements and implications of such an upgrade. Always consult with a professional if you’re unsure about any aspect of the process.
Remember, the goal is not just to increase power, but to improve the overall performance and reliability of your vehicle. So, take your time, do your research, and ensure that your upgraded Jimny continues to deliver the performance and reliability that Suzuki is known for.
Here are the performance specifications for each motor:
- M13A VVT Motor: This motor can produce from 88 PS (65 kW; 87 HP) at 6,000 rpm to 91 PS (67 kW; 90 HP) at 6,000 rpm of maximum horsepower and 118 N·m (12 kg·m, 87 ft·lb) at 3,400 rpm of peak torque12.
- M15A Motor: The M15A motor can produce 100 PS (74 kW) at 5,900 rpm and 133 N·m (98 lb·ft) at 4,100 rpm3. This represents a significant increase in both horsepower and torque compared to the M13A VVT motor.
- M16A Motor: The M16A motor can produce from 106 PS (78 kW; 105 HP) at 5,900 rpm to 136 PS (100 kW; 134 HP) at 6,900 rpm of maximum horsepower and from 145 N·m (14.8 kg·m, 106.9 ft·lb) at 4,100 rpm to 160 N·m (16.3 kg·m, 117.9 ft·lb) at 4,400 rpm of peak torque4. This is a substantial improvement over both the M13A VVT and M15A motors.
- M18A Motor: The M18A motor can produce 125 PS (92 kW) at 5,500 rpm and 170 N·m (125 lb·ft) at 4,200 rpm5. This is the highest performance from the four Suzuki Jimny motor upgrades.
Please note that these are the standard performance specifications for each motor. Actual performance may vary depending on the specific vehicle, driving conditions, and any modifications made to the engine or vehicle.
