The Suzuki K6A turbo refers to the turbocharged version of Suzuki’s K6A engine, a 658cc, 3-cylinder, DOHC engine found in many Suzuki kei cars, including the Alto, Wagon R, and Jimny. The turbocharger increases power and responsiveness by forcing more air into the cylinders for more efficient fuel combustion. Key features include dual overhead camshafts (DOHC) for precise valve control, variable valve timing (VVT) to optimize performance across RPM ranges, and a timing chain for durability.
- Engine Type: 3-cylinder, DOHC (Dual Overhead Camshaft) aluminum block.
- Displacement: 658cc (0.66 L).
- Valvetrain: 12-valve DOHC, often with Variable Valve Timing (VVT).
- Turbocharger: The primary feature that boosts power by compressing and forcing air into the engine’s cylinders.
- Fuel System: Distributed fuel injection.
- Durability: Features a durable timing chain instead of a timing belt.
- Exhaust Gas: Exhaust gases spin a turbine in the turbocharger.
- Compressor: The spinning turbine drives a compressor, which draws in and compresses outside air.
- Engine Intake: The compressed air is forced into the engine’s cylinders.
- More Power: With more air, the engine can burn more fuel, resulting in increased power and better performance.
Benefits of the turbocharger:
- Increased Power:Significantly increases the engine’s power output for better acceleration and responsiveness.
- High Altitude Performance:Compensates for lower air density at high altitudes, ensuring consistent engine performance.
- Improved Efficiency:Optimizes the combustion process, which can improve fuel efficiency.
The Suzuki K6A turbo is a 658cc, inline 3-cylinder, DOHC engine with a 68 mm x 60.4 mm bore and stroke, a compression ratio of 8.4–8.9, and typically produces 60–64 PS (44–47 kW) at 6000–6500 rpm, with maximum torque of 83–108 N⋅m (61–80 lb⋅ft) at 3000–3500 rpm. It features an aluminum block, cast-iron liners, a timing chain, DOHC 12-valve cylinder head, and is known for its compact size and use in various Kei cars, microvans, and other vehicles.

Features and Applications
- Turbocharging: Equipped with a turbocharger for increased power output.
- Timing Chain: Uses a timing chain, rather than a belt, for engine timing.
- Applications: Found in a wide range of vehicles, including the Suzuki Wagon R, Alto, Kei, MR Wagon, and Carry/Every, as well as their Mazda equivalents.
- Compact and Lightweight: Designed to be small and light, making it suitable for Kei vehicles.
- Fuel Efficiency: Known for good fuel efficiency, partly due to its all-aluminum construction and low-tension piston rings.
- Reliability: Generally regarded as a reliable engine.
- Because performance figures can vary by vehicle and model year, it is best to consult the service manual or specifications for the exact vehicle to get precise details.
