Garrett 851154-5001S Supercore GTX Series GTX3076R, Trim 58

Garrett GTX3076R supercore — a balanced core assembly (centre cartridge with compressor cover and back plate) for building or rebuilding GTX turbochargers.

The GARRETT 851154-5001S GTX3076R Gen II turbocharger is supplied without a turbine housing and represents the next evolution of the GTX series.

Developed using Garrett’s proprietary CFD-based simulation technology, the wheel design optimizes mass airflow and efficiency, providing a broader tuning range.

The 8 mm dual ceramic ball bearing cartridge ensures fast spool and improved reliability by reducing shaft motion.

A newly engineered high-flow compressor housing with a fully machined inlet, outlet, and ported shroud supports maximum performance and precise fitment.
