We have developed a K04 hybrid turbocharger upgrade for the Gen II Mini designed to support over 320hp while maintaining the Mini’s point and shoot throttle response.
Most large compressor wheels can be a hindrance to response time so the X46 feature a compressor wheel that weighs only slightly more than the JCW compressor wheel.
While getting more air into your engine is important, so is getting it out, and as efficiently as possible. To that end the our turbos use a custom matched turbine wheel to reduce back pressure allowing the engine to breath more freely and produce more horsepower.
Each X46 is built from a brand new Borg Warner turbocharger so you know your getting quality from the start. You also get the peace of mind that comes from knowing your X46 comes with a two year, 20,000 mile warranty. In addition, each unit is shipped configured to retain complete ECU control of the turbo just like the OEM. Since each X46 is built to order please allow two to three weeks for machining, balancing and assembly.
