Dorch DS25 High Pressure Fuel Pump Upgrade - Gen 2 B58 / Supra

The Gen 2 B58 (B58TU) and the GR Supra run a 350 bar fuel system, so a Gen 1 pump won't do. Dorch's DS25-350 is its DS25 pump reworked for 350 bar. It drops into the factory position and stays under full control of the DME.

What you get

• DS25-350 high-pressure fuel pump with mounting hardware.
• Dorch high-pressure line rated to 350 bar.
• Low-pressure hose and a plug-and-play adapter harness.

Flow, as Dorch rates it

• Gasoline: about 850 whp (about 1,000 whp with Dorch's +27% cam upgrade).
• E50: about 720 whp (900 whp with the cam).
• E85: about 620 whp (770 whp with the cam).

Good to know

• To use the pump's full flow you also need bigger injectors. Dorch's budget pairing is the S58 OEM injector upgrade, which adds about 30% flow over stock.
• Dorch's kits are built as a drop-in for the factory pump position: the hoses follow the OEM routing, nothing is cut or bent, and the DME keeps full control of the pump. Each kit comes with Dorch's own high-pressure line to the fuel rail instead of reusing the factory line, and Dorch backs its pumps with a lifetime warranty.
• The pump needs software that supports it. Dorch's in-house calibration team supports its pumps, so tell your tuner which pump you're running.
• Already running an ethanol sensor? Tell us when you order and we'll get the matching hoses from Dorch.
• Fits Gen 2 B58 cars: Toyota GR Supra 3.0, Z4 M40i, M240i (G42), M340i (G20), M440i (G22), 840i, X5/X6/X7 40i, and the 540i, 740i and X3/X4 M40i from the 2020 model year on. Pick your car group in the Fitment option.
