Mercedes G Class Diesel Performance Package

G-Class Diesel Performance Package

The Overland-G Performance Package is configured for diesel conversion builds where increased output and durability are required beyond standard engine setup.

System Purpose

This package is developed for vehicles operating under sustained load — including expedition travel, towing and high-demand driving conditions. The focus is on stable performance, controlled temperatures and long-term reliability.

Turbocharger Upgrade

The system includes an upgraded turbocharger designed to improve airflow and torque delivery across the usable range. This allows the engine to maintain consistent performance under load without excessive stress.

Valve Train Reinforcement

Reinforced valve springs are included to support higher boost levels and extended operation under increased pressure. This ensures mechanical stability during continuous load conditions.

Engine Calibration

The package is completed with recalibrated engine control software. The calibration is matched to the hardware configuration, ensuring consistent power delivery, drivability and engine response.

Configuration

The setup is defined based on engine type — OM612, OM613 or OM648 — and the intended use of the vehicle. There is no fixed specification; each configuration is matched to the build.

System Integration

This package is typically installed as part of the complete Overland-G Diesel Engine Conversion Kit, where engine, cooling and electronics are configured together.

Application

Used in builds where standard output is insufficient or where additional durability is required under continuous load.
