Dorch Stage 3 HPFP Upgrade – BMW B58 Gen2 / Toyota GR Supra

OVERVIEW

The DS3 (Dorch Stage 3) is Dorch's largest-bore, highest-flowing single high pressure fuel pump, developed with Stanadyne's 12 mm bore pump family. This is the 350 bar version for the Gen2 (B58TU) engine, rated at about 20% more fueling than the Gen2 DS25.

The DS3 is a complete plug-and-play kit that installs in the factory location with no cutting, bending or crimping, and the DME keeps full high-speed pressure regulation and safety control. Paired with larger injectors and the Dorch +27% cam upgrade, it supports four-digit power on direct injection alone.

Additional Parts Required

• Software changes are required to run this pump. Dorch is adding a pump-upgrade option to BOOTMOD3 and MHD; until it is listed for your car, send your .BIN file to tuning@dorchengineering.com for the appropriate WinOLS implementation. Compatible platforms we stock: BOOTMOD3 B58 Tune (BMW), BOOTMOD3 B58 Tune (GR Supra), MHD Super License – B58 and MHD Super License – GR Supra.
• ECU unlock is required before a locked B58 DME can be flashed — see our ECU Unlock Service for BMW B58 Engines.
• Larger direct injection injectors are required to use the DS3's full potential — Dorch notes OEM S58 injectors are not enough for this pump. Contact Speed Logic for an injector recommendation.
• If your car already has an ethanol sensor, choose your chassis fitment and add "ECA HOSES" in the order notes.
