This is a high-performance upgrade turbocharger designed as a direct-fit replacement for the factory turbo on BMW B58 Gen2 engines with the 2-port cylinder head configuration. It is intended for vehicles that use the 2-port (not 6-port) manifold/head design, which is common on many G-series BMWs and related platforms. Always verify exact fitment against your vehicle’s original turbo part number and manifold type.
The product is offered in Stage 2 and Stage 3 versions, each available with or without a solenoid valve.
The 2-port unit focuses on substantially increased airflow while retaining a bolt-on installation that uses the original mounting points, oil lines, and coolant lines where possible.
Key features：
Higher power potential — Stage 2 is positioned to support roughly 700 hp and Stage 3 around 800 hp when paired with appropriate supporting modifications (fuel system upgrades, intercooler, downpipe, intake, etc.), quality fuel, and professional calibration. These figures are approximate and depend heavily on the rest of the build; the stock turbo is typically limited closer to the ~400 hp range under similar conditions.
Larger billet compressor wheels — Both versions use billet CW representing a clear increase over the OEM compressor for improved flow and efficiency.
Improved inlet and compressor housing — Larger inlet diameters (significantly bigger than the factory ~56 mm) reduce restriction.
Upgraded turbine side — Larger turbine wheel for greater exhaust flow capacity and higher power potential while aiming to keep spool characteristics usable for street/track use.
VSR high-speed balancing — The rotating assembly is precision balanced (VSR) for smoother operation, reduced vibration, and improved durability at elevated boost and RPM.
Optional solenoid valve — Available with or without the electronic wastegate/solenoid control valve depending on your preferred control strategy and existing setup.
Direct replacement design — Engineered to bolt into the stock location on compatible 2-port Gen2 B58 applications, minimizing fabrication.
