Product Description

The Garrett 934173-5002S is the GXR42-72 super core from Garrett's G-XRace series - engineered for serious motorsport and drag racing applications. With a 72.9 mm compressor inducer and 102 mm exducer, paired with a trim of 51 and A/R 0.85, it delivers a broad, efficient airflow range. On the turbine side, the 82.0 / 75.0 wheel with trim 84 offers strong exhaust flow, supporting up to ~1,450 hp in optimized builds.

Because this is a core unit (CHRA + compressor wheel + internal assembly) rather than a full turbo, it does not come with turbine housing, actuator, or external plumbing. It is intended for custom and racing setups. The design retains compatibility with Garrett G / G42 series turbine housings, making it easier to integrate into existing systems.

Installation requires precise matching of manifold runner geometry, oil feed / return, water cooling lines, and balance of intake/exhaust plumbing. It is not a plug-and-play solution. Use only in dedicated racing or motorsport applications; it is not street legal in many jurisdictions.
