What are the key differences between the N55 and B58 engines?

If you own a BMW with either an N55 or B58 engine, you might be wondering which one is better for remapping. Both engines are great choices for those looking to improve their car’s performance, but they do have some key differences that are worth exploring.

First, let’s take a look at the N55 engine. This engine is a turbocharged inline-six that was used in a variety of BMW models, including the 135i, 335i, and 535i. It’s known for its smooth power delivery and impressive torque output, making it a popular choice for those who enjoy spirited driving. With a stage 1 remap, you can expect to see power gains of around 50-60 horsepower and around 70-80 lb-ft of torque. This will result in improved acceleration, better throttle response, and an overall more engaging driving experience.

On the other hand, the B58 engine is a newer design that is currently used in a variety of BMW models, including the 340i, 440i, and the M240i. It’s also a turbocharged inline-six, but it features a number of improvements over the N55, including a redesigned intake and exhaust system, improved fuel delivery, and more advanced engine management software. With a stage 1 remap, you can expect to see power gains of around 60-70 horsepower and around 80-90 lb-ft of torque. This will result in even more impressive performance, with improved acceleration, faster response times, and an overall more exhilarating driving experience.

So, which engine is better for remapping? Well, it really depends on what you’re looking for. If you’re looking for a tried and true engine that’s been proven in a variety of BMW models, the N55 is a great choice. It’s a reliable engine that can handle a lot of power, and it’s already capable of producing impressive performance straight out of the factory. On the other hand, if you’re looking for the latest and greatest in engine technology, the B58 is the way to go. It’s a more advanced engine that features a number of improvements over the N55, and it’s capable of producing even more impressive performance gains with a stage 1 remap.

At the end of the day, both the N55 and B58 engines are great choices for those looking to improve the performance of their BMW.
