Dorch DS3 High Pressure Fuel Pump Upgrade - Gen 2 B58 / Supra

The DS3 is Dorch's highest-flow single pump for the Gen 2 B58 and GR Supra. It has Dorch's largest bore and runs at 350 bar, with about 20% more fuel than the DS25.

What you get

• DS3 high-pressure fuel pump with mounting hardware.
• Dorch high-pressure line rated to 350 bar.
• PTFE low-pressure line, plus the hose and harness for a plug-and-play install.

Flow, as Dorch rates it

• Gasoline: about 950 whp (about 1,150 whp with Dorch's +27% cam upgrade).
• E50: about 800 whp (1,000 whp with the cam).
• E85: about 700 whp (870 whp with the cam).

Good to know

• Dorch says the DS3 needs injectors larger than the S58 OEM ones to reach its full potential.
• 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.
