Unleashing the Power of the OM605 Turbo Performance Upgrades with Benz Injection




Understanding the OM605 Turbo Engine

The OM605 engine, produced between 1993 and 2001, features a cast-iron block and aluminum cylinder head, utilizing a double overhead camshaft (DOHC) configuration with four valves per cylinder. In its turbocharged form, the OM605 delivers up to 110 kW (148 hp) and 280 Nm of torque. The turbocharged variants, such as the OM605.960 and OM605.962, come equipped with an intercooler and a Bosch electronically controlled inline injection pump (ERE), enhancing fuel delivery and overall efficiency. 

Upgrading Fuel Injection with Benz Injection

A critical aspect of enhancing the OM605's performance lies in optimizing the fuel injection system. Benz Injection offers performance mechanical injection pumps tailored for the OM605 engine These pumps are built with larger elements, such as 7.5 mm or 8.0 mm, allowing for increased fuel delivery essential for higher horsepower applications. Each pump is meticulously assembled, calibrated, and tested to ensure optimal performance. Upgrading to a performance injection pump can significantly boost the engine's power output, especially when paired with other modifications. 

Enhancing Turbocharging Capabilities

To complement the upgraded fuel system, enhancing the turbocharging capabilities is paramount. Benz Injection provides hybrid turbochargers designed to fit the OM605 engine. These turbos feature improved blade designs and larger compressor and turbine wheels, resulting in over 20% increased airflow. The hybrid turbo is engineered for better top-end performance while maintaining quick spool times, making it an ideal choice for those seeking a balance between daily drivability and performance. 

Optimizing Engine Control with Tuned ECUs

For those utilizing the electronic diesel control (EDC) system, upgrading the engine control unit (ECU) is crucial. Benz Injection offers tuned ECUs that eliminate restrictive features like the EGR and MAF sensors, allowing for more aggressive tuning. These ECUs are available in various stages, with Stage 2 supporting up to 280–300 hp when paired with appropriate turbo and injection pump upgrades. The tuned ECU ensures that the engine operates efficiently with the increased fuel and air delivery, maximizing performance gains. 

Importance of Upgraded Injectors

Upgrading the injectors is essential to handle the increased fuel flow from performance injection pumps. Benz Injection offers both rebuilt and new injector sets for the OM605 turbo engine. These injectors are calibrated to higher pop pressures, ensuring precise fuel atomization and combustion. Properly matched injectors contribute to smoother engine operation, improved throttle response, and reduced emissions, all while supporting higher horsepower levels. 

Comprehensive Performance Packages

For enthusiasts seeking a complete performance solution, Benz Injection provides comprehensive turbo kits tailored for the OM605 engine. These kits include a high-performance turbocharger, tuned ECU, exhaust manifold adapter, custom downpipe, and all necessary hardware for installation. Designed for ease of installation, these kits eliminate the guesswork involved in sourcing compatible components, ensuring a seamless upgrade path to achieve up to 300 hp.
