Unlock the Full Potential of Your BMW B58 Gen 2

Take your build beyond factory fueling limits with the Dorch DS25 (Stage 2.5) and DS3 (Stage 3) High Pressure Fuel Pump (HPFP) upgrades—engineered specifically for the BMW B58 Gen 2 platform. Developed by the pioneers of direct-injection fueling upgrades, these next-generation pumps deliver industry-leading flow, OEM-level integration, and unmatched reliability.

Whether you're chasing a reliable street setup or 4-digit horsepower, the DS25 and DS30 provide scalable fueling solutions without compromising drivability or safety.


🚀 Why Upgrade Your HPFP?

The factory HPFP becomes a bottleneck as power increases—especially on ethanol blends. Upgrading to a high-performance HPFP allows you to:

  • Support significantly higher horsepower & torque
  • Run E85 / ethanol blends safely
  • Maintain stable fuel pressure under boost
  • Enable larger turbos & aggressive tuning
  • Preserve OEM drivability and DME control

In short: more fuel = more power, safely.


⚙️ DS25 vs DS3 – What’s the Difference?

🔧 DS25 (Stage 2.5) – Performance Street & Hybrid Turbo Builds

  • Up to 770whp (gas) / 560whp (E85)
  • With upgraded cam: 950whp (gas) / 710whp (E85)
  • Ideal for hybrid turbos, daily drivers, and strong street builds
  • Excellent pairing with OEM+ injector setups (e.g. S58 injectors)

🔥 DS3 (Stage 3) – Maximum Flow & Big Power Builds

  • Up to 950whp (gas) / 700whp (E85)
  • With upgraded cam: 1150whp (gas) / 870whp (E85)
  • ~20% more fueling capacity than DS25
  • Designed for big turbo & high ethanol builds
  • Requires larger injectors for full potential

👉 Summary:

  • Choose DS25 for powerful, responsive street setups
  • Choose DS3 for maximum fueling capacity and extreme horsepower goals

🧠 Advanced Engineering – 350 Bar Performance

Both pumps feature a completely redesigned internal architecture, including:

  • Optimized plunger geometry & depth
  • Revised spring rates
  • Increased volumetric efficiency
  • 350 bar operating pressure (Gen 2 B58 optimized)

Result: consistent, reliable fueling at power levels the OEM system simply cannot support.


🔌 True Plug & Play – OEM Integration

Unlike other aftermarket solutions, Dorch delivers a 100% plug-and-play HPFP upgrade:

  • ✅ No cutting, bending, or modifications
  • ✅ Includes 350 bar high-pressure hardline
  • ✅ Full DME control retained
  • ✅ OEM-level safety systems remain active

This is the only true OEM-fit HPFP upgrade available for the B58 Gen 2.

Stylish, Comfortable, and Great for Everyday Wear
Size: 11, Color: Grey
The Marc Joseph New York Men’s Edison Street shoes are a standout — stylish enough for work or a night out, but comfortable enough for daily wear. The hands-free technology makes them easy to slip on and off without sacrificing fit or support. They have a polished, classic look that pairs well with both casual and dressier outfits, and the comfort level stayed high even after a full day on my feet. Good quality, flattering design, and a versatile choice if you want shoes that look sharp and feel great. Would recommend and buy again.

Just Slip On & Go
Size: 13, Color: Black/Black
These are honestly one of the easiest shoes I’ve owned. You just step in and go, no laces to deal with, but they still have that lace look which I like. I’ve had them for close to a year and they’ve held up well. Comfortable enough for everyday use. I liked them enough and got a few different versions of the same shoe. The elastic fit is what makes them stand out. If you want something simple, comfortable, and still a little dressy, these are solid.
