DORCH | B58 Gen 1 HPFP Upgrade DS25 / DS3 (Stage 2.5 / Stage 3)
High-Performance HPFP Upgrade for BMW B58 Gen 1
Upgrade your fueling system with the Dorch DS25 (Stage 2.5) and DS3 (Stage 3) High Pressure Fuel Pump (HPFP) upgrades, engineered specifically for BMW B58 Gen 1 engines. Designed by the pioneers of B58 direct-injection fueling, these pumps deliver massive flow increases, OEM-level integration, and proven reliability for high-performance builds.
Whether you're running a hybrid turbo street setup or a full big turbo build, Dorch HPFP upgrades eliminate fueling limitations and unlock the full potential of your B58.
🚀 Why Upgrade Your B58 Gen 1 HPFP?
The factory HPFP quickly becomes a restriction when increasing boost or running ethanol blends. Upgrading to a high-performance HPFP allows you to:
- Support 750–1150+ WHP builds
- Safely run E50 / E85 fuel mixtures
- Maintain consistent rail pressure under load
- Maximize performance of larger turbos & upgraded injectors
- Retain OEM drivability and DME safety controls
⚙️ DS25 vs DS3 – Key Differences
🔧 DS25 (Stage 2.5) – Optimized Performance & Reliability
- Up to 750whp (gas) / 550whp (E85)
- With 40% cam upgrade: 1000whp (gas) / 770whp (E85)
- Operates efficiently at 250 bar
- Perfect for hybrid turbo and aggressive street builds
- Designed to maximize performance of upgraded DI injectors
🔥 DS3 (Stage 3) – Maximum Fueling Capacity
- Up to 860whp (gas) / 630whp (E85)
- With 40% cam upgrade: 1150whp (gas) / 870whp (E85)
- ~20% more flow than DS25
- Ideal for big turbo & high ethanol setups
- Built for extreme horsepower goals
👉 Summary:
- DS25 = Best balance of power, efficiency, and reliability
- DS3 = Maximum flow for high-end, big turbo builds
🧠 Redesigned for Maximum Efficiency
The DS25 and DS3 feature a complete internal redesign, including:
- Optimized pressure chamber design
- Revised spring rates & plunger geometry
- Increased volumetric efficiency
- Stable operation up to 250 bar
Result: higher flow, improved reliability, and consistent fueling under extreme conditions.
🔌 True Plug & Play OEM Fitment
Dorch HPFP upgrades are engineered for seamless installation and factory-level integration:
- ✅ No cutting, bending, or modification required
- ✅ OEM-style hose routing (no interference with maintenance)
- ✅ Includes 250 bar high-pressure fuel line
