Technical Excellence and Wide-Ranging Model Fitment

TheFuchuan BMW N55B30 Engine Assembly is engineered with an all-aluminum crankcase and utilizes a single twin-scroll turbocharger to virtually eliminate turbo lag. It integrates BMW’s most advanced valvetrain technologies, including Valvetronic III and Double-VANOS. Key technical specifications include:

• Displacement: 2,979 cc (3.0L)

• Bore x Stroke: 84.0 mm × 89.6 mm

• Compression Ratio:10.2:1

• Power Output: Approx. 225–250 kW (302–335 hp) @ 5800 rpm

• Torque: 400–450 Nm @ 1200–5000 rpm

This assembly is the primary heart for a vast array of BMW"35i"models, including the 335i (E90/F30),535i (F10),X3 (F25),X5 (E70/F15), and X6 (E71/F16). By supplying the Fuchuan BMW N55B30 Engine Assembly, distributors can meet the technical demands of the prestige SUV and sport sedan markets.

Advanced TwinPower Engineering and Dynamic Balance

A defining characteristic of the Fuchuan BMW N55B30 Engine Assembly is its inherent primary and secondary balance, a hallmark of the inline-six configuration. Our manufacturing process emphasizes the high-pressure die-cast aluminum architecture and the use of a forged steel crankshaft to handle the high-torque loads of the twin-scroll turbo. The Fuchuan BMW N55B30 Engine Assembly features third-generation Valvetronic variable valve lift and precision direct injection, which significantly improves throttle response compared to its predecessors. These material choices and engineering tolerances ensure that the Fuchuan BMW N55B30 Engine Assembly delivers the signature"silky smooth"acceleration that BMW enthusiasts expect, alongside improved thermal management.

Stringent Quality Control and VANOS/Valvetronic Validation

To safeguard the interests of our global B2B partners, every Fuchuan BMW N55B30 Engine Assembly undergoes a rigorous multi-stage validation sequence. Because the N55 relies heavily on precise oil pressure for its variable valve timing, each unit is subjected to a mandatory hot-run test. During this verification, our engineers monitor Double-VANOS solenoid accuracy, Valvetronic motor response, and oil pressure stability at peak operational temperatures. We also perform exhaustive diagnostic scans of the high-pressure fuel system. This commitment to quality ensures that each Fuchuan BMW N55B30 Engine Assembly arrives at your facility in peak mechanical condition, backed by our professional 12-month factory warranty.
