Bosch high-pressure fuel pump B58 TU (350 bar) – upgrade for BMW B58 Gen 1 and Toyota GR Supra

Bosch high-pressure fuel pump for fuel (HPFP) from the B58 TU engine upgrade for B58 Gen 1. Gen 1 has a factory 200-bar pump, which is plenty at stock power, but above about 450 HP it becomes a bottleneck: fuel pressure drops at full throttle, the ECU sees a lean condition and pulls timing. The TU engine got a stronger 350-bar pump — and it is a direct swap into Gen 1.

What you get

• The original Bosch pump, as fitted by BMW to the B58 TU — with no compromise in quality
• Direct replacement (plug and play) — no adapters, no modifications

What you get

• Stable fuel pressure up to approx. 600 hp on petrol — enough headroom for a hybrid turbo
• End of the full-throttle lean condition that is the most common reason on Gen 1 above 450 HP for timing pull
• Predpogoj for Stage 3: without this pump the turbo will not deliver what you paid for

Compatibility — B58 Gen 1 (B58B30M0)

• BMW M140i (F20/F21), M240i (F22/F23), 340i (F30/F31/F34), 440i (F32/F33/F36)
• BMW 540i (G30/G31), 640i (G32), 740i (G11/G12), X3/X4 M40i (G01/G02), Z4 M40i (G29) — model years up to mid-2019
• Toyota GR Supra 3.0 (2019–2020, pre-TU)
• Cars with the TU engine already have this pump — they do not need the upgrade.

Important

• After installation a calibration adjustment is requiredso the ECU can use the higher pressure. We’ll arrange an appointment together write to us.
• Above 600 HP we recommend adding port injection — we’ll advise based on your goal.
