FAQs

Is the BMW N55 better than the N54?

The BMW N55 is generally considered more reliable than the N54. There are fewer reported issues and a simpler design is detected in N55. But, the N54 offers more tuning potential and a more engaging driving experience due to its twin-turbo setup. 

Can you put the N55 turbo on the N54?

You can put an N55 turbo on an N54 engine, but it might require significant modifications to the engine and exhaust manifold. It's technically feasible, but we do not recommend it for those without extensive mechanical knowledge and experience.

Is the N55 engine forged?

No, the stock N55 engine is not forged. It comes with cast pistons and connecting rods. The best you can do is upgrade the N55 with forged internals. Most car tuners use this as a common modification to push the limits of their N55-powered vehicles.

What is the weak point of the N55 engine?

The N55 engine has the potential for rod bearing failure, especially in higher-mileage or heavily modified vehicles. That’s why we suggest drivers monitor oil pressure and change the oil and filter regularly to eliminate this risk. If you change the rod bearing, you can pretty much ensure the engine's longevity.

When did N55 replace N54?

The BMW N55 engine began production in 2009 and gradually replaced the N54 engine in various BMW models. There have been some overlaps in 2009 and 2010; but the N55 became the standard engine for most N54-powered models by 2011.

What size turbo is the N55?

The N55 engine uses a BorgWarner B03 turbocharger with a custom 62mm compressor wheel. From this setup, you can get a balance of performance and efficiency for delivering higher power and torque across the rev range.

How long can an N55 last?

If you maintain it properly, the N55 engine can easily last over 150,000 miles. Even many owners report exceeding 250,000 miles. To get that much-overclocked performance, you can conduct regular oil changes and coolant flushes.
