Reliability, problems and repair of the BMW N54B30 engine

The powerful N54 twin-turbocharged inline-six was developed by Alpina in 2006 for fast civilian cars and BMW crossovers. The basis was an aluminum cylinder block M54B30 with cast iron liners, covered on top with a new cylinder head with a Bi-VANOS variable valve timing system on the intake and exhaust shafts and direct fuel injection. The diameter of the intake valves is 31.44 mm, exhaust valves 28 mm. Characteristics of camshafts on N54 (intake/exhaust): phase 245/261 lift 9.7 mm. There is no Valvetronic valve lift system here. Supercharging is realized using two Mitsubishi TD03-10TK3 turbochargers, blowing in parallel, each into its own three cylinders. The boost pressure on a standard engine is 0.55 bar. Siemens MSD 80/MSD 81 engine management system.

The N54B30 engine was used in BMW cars with the 35i index (40i for the 7-Series). In addition, the engine was used by Alpina, modified to 360 hp. and 400 hp options.
