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.

For engine and turbocharger reliability, JMTC recommends a 3.0" or larger downpipe/exhaust size for the GTD turbochargers. Please avoid using the stock downpipe or stock-sized catalytic converter.
The OEM intake boot can be used with the removal of the inner sleeve for N14 engines. For N18 engines, the OEM boot at the turbo connection will need to be heated and expanded slightly, which can be done with a heat gun. This turbocharger also fits AEM intake, NM Eng intake, and Forge Intake (Boot). Please note that the hose might need to be warmed and stretched over with a hose expander.
