If you drive a BMW with an N55 engine, you may have put some serious mileage on the odometer and the turbo. Alternatively, you may have acquired a pre-owned BMW running this platform and want to make an <a href="https://vargasturbo.com/product/n55-stage-1-jb-upgrade-kit-new/">N55 turbo upgrade</a> to get more horsepower out of it.   <figure class="wp-block-image aligncenter size-large is-resized"><a href="https://vargasturbo.com/product/vtt-n55-gc/"><img src="https://vargasturbochargertechnologiesblog.wordpress.com/wp-content/uploads/2026/02/copy-of-8.jpg?w=500" alt="Two VTT turbochargers side by side with billet compressor wheels—one gold, one purple—shown in a clean studio setting." class="wp-image-146" style="width:445px;height:auto"/></a></figure>   The N55 is a straight-six, factory-turbocharged engine that first hit production cars in 2009. However, it officially left the production line (in obscure models) in 2021. In 2026, it may be time to make a few upgrades to get more out of your BMW. Is now the right time to upgrade your vehicle’s turbo?   You’re Interested In Swapping Your Current Turbo   Whether you’re driving a high-mileage N55, you’ve picked up a pre-owned BMW with the N55, or you simply aren’t impressed by your car’s current numbers, there are several reasons to replace the existing turbo.   Swapping out the current turbo gives you more control. It gives you the opportunity to swap out the turbo and other parts, allowing you to hit the reset button on the turbo performance. Upgrading everything from the turbo to the coolant hoses makes a noticeable difference.   You’re Interested in a Turbo That Goes Beyond Factory Specs   Do you want a <a href="https://vargasturbo.com/product/vtt-n55-gc/">BMW N55 turbo</a> upgrade that goes above factory specs? Swapping out the OEM turbo for a different OEM turbo in better shape is always an option, but far from the only one. There are aftermarket N55 turbos that take the base design of the OEM turbo and refine it.   <figure class="wp-block-image aligncenter size-large is-resized"><a href="https://vargasturbo.com/product/n55-stage-1-jb-upgrade-kit-new/"><img src="https://vargasturbochargertechnologiesblog.wordpress.com/wp-content/uploads/2026/02/copy-of-img_0521.jpg?w=500" alt="Close-up of VTT Stage 1 turbocharger with blue compressor wheel and red intake cap for BMW N55 PWG engine." class="wp-image-148" style="aspect-ratio:1.5;width:493px;height:auto"/></a></figure>   Get a new turbo made with high-end materials and parts. With improved design elements, like a larger inlet area and improved bearing housing oil structure, you can enjoy a serious performance upgrade. Plus, there are turbo upgrades that feature a drop-in design that retains factory-style connections, making installation easier. You’re Interested in Higher Performance Numbers   If you’re interested in seeing improved numbers on your dyno chart, upgrading your turbo is an essential step to achieving exactly that. The key is choosing the right turbo upgrade, depending on the numbers you want to see.   You could also explore kits to <a href="https://vargasturbo.com/product/n55-stage-1-jb-upgrade-kit-new/">upgrade BMW N55 turbo</a> parts. Search for a kit with a Stage 1 turbo, a custom reverse billet compression wheel, and a new turbine. You can even get the installation kit to go along with it.   <figure class="wp-block-image aligncenter size-large is-resized"><a href="https://vargasturbo.com/product/vtt-n55-gc/"><img src="https://vargasturbochargertechnologiesblog.wordpress.com/wp-content/uploads/2026/02/copy-of-img_1462.jpg?w=500" alt="Turbocharger components with VTT branding, showing turbine wheel, housing, and exhaust manifold." class="wp-image-149" style="aspect-ratio:2.1191607559469627;width:492px;height:auto"/></a></figure>   About Vargas Turbocharger Technologies   Do you want to get more horsepower out of your BMW?
