BorgWarner Turbos for MINI

Clear BMW chassis

Please ensure your correct model is selected

If more boost and reliability are your goals choose from one of our BMW turbo upgrades. Our turbo upgrades range from stock turbos rebuilt with stronger internals to all-new, ground-up turbo upgrades. BMW turbos such as the N54 are capable of really impressive power numbers on stock engine internals but the factory turbos lack the precise tolerances and reliability that an upgraded unit will deliver. In other words, the stock turbos can only do so much and if big power (>400whp) is your goal a turbo upgrade must be in your plans. Our partners are leading experts in turbo technology and upgrades. Each Stage has been professionally developed and tested. Additional upgrades and tuning may be, or is, required. Contact us for more details on tuning options.

For those seeking a top-tier OE replacement upgrade turbo for their 1.6L car, the BorgWarner unit is the ultimate solution. It seamlessly replaces vehicles originally equipped with MINI Factory Borg Warner Turbochargers, offering an upgraded alternative for both the Cooper S and JCW models.

Keep in mind that the larger inlet necessitates an aftermarket intake system featuring a silicone hose or an aftermarket silicone intake hose to adapt to the larger inlet. Adjustments to factory inlet boots may be required for proper fitting.

With a piggyback tune, this turbo delivers power ranging from 225 to 255HP. With a more aggressive tune, you can push the limits up to 300HP. However, it's crucial to acquire a custom flash tune (not supplied) to prevent the turbo from backing off during full pulls.

Warranty claims for this turbo upgrade must be supported by a receipt from a professional repair facility, indicating the installation date and vehicle mileage. Additionally, a separate receipt from a professional repair facility should accompany the warranty claim, specifying the date and mileage of the turbocharger failure, reasons for the failure, and proposed repair solutions if necessary. Borg Warner will consider replacing a failed turbocharger due to material and workmanship defects, provided proper documentation is provided. Please note that all associated labor charges for diagnosis and repair are the responsibility of the vehicle owner.
