Garrett G38-1000 62mm G-Series II Supercore

Garrett G38-1000 62mm G-Series II Supercore | 1000 HP Turbo

Unlock up to 1000 HP with the Garrett G38-1000 G-Series II Supercore. Features 62mm compressor, Inconel turbine wheel, and dual ceramic ball bearings

The Garrett G38-1000 62mm G-Series II Supercore represents the pinnacle of modern turbocharger engineering for high-horsepower street and motorsport applications. Rated for 500 to 1,000 horsepower on engines ranging from 2.0L to 5.5L, this supercore directly competes in the popular 6266 performance segment while delivering superior airflow efficiency and thermal resistance.

At its heart, the G-Series II platform features an optimized forged, fully-machined aluminum compressor wheel that delivers significantly increased airflow over Gen I designs. Paired with a high-flow Inconel turbine wheel designed to withstand extreme exhaust gas temperatures up to 1050°C, this supercore delivers rapid spool-up, massive top-end power, and rock-solid reliability under intense boost pressures.

Product Details

1. Compatibility: Universal Performance & Motorsport Applications (2.0L – 5.5L engine displacements)
2. Part Number: 938272-5003S
3. Power Rating: Up to 1,000 HP
4. Rotation: Standard Rotation (Right-Hand)
5. Bearing System: Dual Ceramic Ball Bearing
6. Cooling: 4-Port Water-Cooled CHRA with dual piston ring sealing
7. Sensor Port: Pre-machined port for optional turbo speed sensor installation

Key Features

1. G-Series II Compressor Aerodynamics: CFD-designed forged aluminum compressor wheel delivering higher pressure ratios and cooler, denser charge air.
2. High-Temperature Inconel Turbine Wheel: 74mm inducer / 66mm exducer wheel engineered to endure continuous exhaust gas temperatures up to 1050°C (1922°F).
3. 4-Port Water Cooling Architecture: Features twin water ports on both sides of the center housing to greatly simplify coolant line routing in tight engine bays.
4. Integrated Speed Sensor Port: Pre-machined housing allows for direct plug-and-play monitoring when paired with Garrett G-Smart or standalone speed sensor kits.
5. Lightweight Aluminum Backplate: Reduces overall turbocharger weight while maintaining structural housing rigidity under high boost loads.

Key Benefits

1. Massive Power Density: Capable of supporting four-digit horsepower figures from a compact 62mm compressor frame.
2. Faster Boost Response: Dual ceramic ball bearing assembly drastically reduces rotational friction for quicker transient throttle response.
3. Maximum Thermal Reliability: Inconel turbine wheel and double piston-ring oil seals prevent fluid blow-by and structural failure under extreme track conditions.
4. Simplified Custom Fabrication: Universal V-Band CHRA interface allows full 360-degree rotation when aligning intercooler piping and oil drain lines.
5. Extended Operating Range: Aero-optimized recirculation channels shift the compressor surge line, allowing a bigger boost at lower airflow without compressor stall.
