Mercedes OM603 & OM606 Fuel Power Package (400HP)

Unlock streetable, reliable power for your Mercedes-Benz OM603 or OM606 diesel engine. The BenzForce Fuel Power Package is a comprehensive, bench-tested upgrade engineered to support up to 400HP when paired with a well-matched turbocharger. Skip the guesswork of sourcing individual fuel components. This complete system brings together a professional-grade, high-output injection pump with precision-shimmed German injectors to transform your classic Mercedes diesel into a high-performance street machine. What’s Included in the Kit: High-Performance Injection Pump Built using a mechanical OM603 pump base (Note: An OM603 core is required before your order ships). Upgraded with genuine Dieselmeken 7.5mm elements and an outside ALDA kit for precise fuel tuning. Professionally assembled, bench-tested, and calibrated for optimal delivery. Finished with a custom side cover, ALDA cap, and fuel block-off plate.

No cores required Professionally shimmed to 150 bar by an authorized Bosch partner for crisp, clean fuel atomization. Fresh heat shields included for a leak-free seal. Heavy-Duty Diesel Return Tubing Upgraded lines that eliminate the cheap, standard hoses that degrade and leak over time. To hit your performance goals, we recommend pairing this fuel package with one of the following turbochargers: BorgWarner S252 (.48 A/R): The ultimate choice for maximum responsiveness and quick spooling on the street. BorgWarner S257 (.63 A/R): Features slightly more lag than the S252 but offers massive pull and airflow on the top end. Holset HE250 (8cm²): A highly capable mid-range performer. Holset HE221 (7cm²): Perfect for a mild, highly responsive daily cruiser, though it will yield lower peak power than larger options. Items Not Included Fuel return line to filter (banjo valve) — 601 070 01 46 Filter housing to injection pump (banjo hollow bolt) — 915036 008202 Linkage Crush washers Installation Notes OM603 rear pump support bracket — The pump must be supported at the rear. A different bolt and appropriately sized spacer(s) may also work. Many customers use an OM602/OM603 filter head because of its simplicity, but the OM606 filter head with the factory plastic lines can also be used.
