Performance & Application
This configuration is purpose-built for platforms that need GT42-level output packaged into a more compact compressor and turbine housing arrangement, making it ideal for engine bays and setups where space is at a premium but big horsepower is still the goal. With full GTX4508R internals, this turbo is engineered to flow more air and handle significantly more boost than earlier generation units in this size class. Expect strong high-RPM power delivery suited to dedicated race builds and high-output street/strip applications. The stainless V-band turbine housing and TiAL construction support fast, reliable installation into modern V-band turbo manifold and downpipe setups.
