Product Description

The B58 engine represents BMW’s B-series modular architecture, displacing 2,998cc with a closed-deck aluminum block and forged crankshaft for exceptional strength. Available in B58B30M0 (320 HP), B58B30M1 (335-382 HP), and B58TU (updated variants) configurations, this powerplant produces 330-369 lb-ft of torque. Compatible with 2016-present BMW 340i, 440i, X3/X4/X5/X6 M40i, Z4 M40i, and 2020-present Toyota GR Supra models, the B58 features Valvetronic variable valve lift and Double-VANOS variable valve timing. Enthusiasts upgrading complete drivetrains should explore our used transmissions including ZF 8-speed automatic and 6-speed manual options. Learn more about BMW modular engines. Every B58 engine undergoes comprehensive boost leak testing, compression analysis, and includes warranty coverage ensuring peak performance and dependability.

Frequently Asked Questions

What vehicles are compatible with the B58 engine for swaps?

The B58 engine fits 2016+ BMW 340i, 440i, 540i, 740i, M240i, X3/X4 M40i, X5/X6 40i, Z4 M40i, and 2020+ Toyota GR Supra. Engine swaps into older BMW E46, E90, and E92 chassis are increasingly popular using custom mounts and wiring harnesses from used engines specialists.

How much horsepower can a stock B58 engine handle with tuning?

Stock B58 engines safely handle 450-500 HP with ECU tuning alone, thanks to forged crankshaft and robust closed-deck block design. With upgraded turbocharger, downpipe, and intercooler, the B58 reliably produces 600-700 HP on stock internals, making it one of the most tune-friendly BMW powerplants ever built.

Is the B58 engine more reliable than the N55 it replaced?

Yes, the B58 demonstrates significantly improved reliability compared to the N55, featuring a stronger closed-deck block, updated cooling system, and refined turbocharger design. Common N55 issues like wastegate rattle and oil leaks were addressed. Most B58 units exceed 150,000 miles with routine maintenance including oil changes every 5,000 miles.

What transmission pairs best with a used B58 engine?

The ZF 8HP 8-speed automatic transmission is the most common pairing, offering lightning-fast shifts and excellent durability. The 6-speed manual (Getrag GS6-53BZ) from Supra models provides engaging driving dynamics. Both options available through our performance transmission inventory ensure optimal power delivery for B58 applications.

Can I use a B58 engine from a Toyota Supra in my BMW?

Yes, the Toyota Supra engine (2.0L and 3.0L variants) shares core architecture with BMW versions, though ECU calibration, wiring harnesses, and accessory drives differ. Successful swaps require BMW-specific engine management software and compatible sensors. The B58 offers excellent cross-platform compatibility with proper adaptation for both brands’ applications.
