PRO Xe 2.7T K04-025 / K04-026 Hybrid Turbo Upgrade
Designed for enthusiasts who want significantly more power while retaining the fast spool and OEM fitment of the factory BorgWarner K04s, the PRO Xe 2.7T Hybrid Turbo Upgrade transforms the legendary Audi 2.7T into a true modern performance platform.
Each turbocharger is completely disassembled, inspected, and precision machined in-house to accommodate an oversized extended-tip billet aluminum compressor wheel and enlarged high-temperature chromium-nickel alloy turbine wheel. The compressor and turbine housings are CNC machined, ported, and hand-finished to maximize airflow while maintaining factory installation compatibility.
Every rotating assembly is dynamically VSR balanced at high speed and assembled with a premium upgraded journal bearing CHRA featuring a 360° thrust bearing, upgraded step-gap turbine seals, and OEM-quality internal components for exceptional reliability under high boost.
Built to support 650+ BHP with the proper supporting modifications, these hybrids deliver a substantial increase in airflow while preserving the rapid spool characteristics that make the 2.7T so enjoyable on both the street and track.
