Product Description:
Garrett G38-1000 62mm 6266 Supercore w/ Compressor Housing - 938272-5003S
G-Series II G38-1000 | 66mm Turbine
G-SERIES II COMPRESSOR AERO
• Improved pressure ratio capability enables increased boost levels for enhanced power output
• High-flow efficiency delivers cooler, denser air to maximize horsepower and engine performance
OEM-LEVEL QUALITY
• Engineered to OEM standards for durability, reliability, and long-term performance
LIGHTWEIGHT PERFORMANCE ADVANTAGE
• Lightweight aluminum backplate to reduce turbo weight
ADVANCED MONITORING CAPABILITY
• Integrated, fully machined sensor port for precise turbo monitoring & tuning
• Use PN 923586-0003 (G-Smart Module/ App) or Speed Sensor Kit 781328-0003 (street kit w/ gauge) or 781328- 0004 (pro kit w/o gauge)
Competitor Frame Size Reference: 6266 (62mm compressor inducer / 66mm turbine exducer)
WARNING: Maximum allowable turbocharger speed is 125krpm. The use of this product above max turbocharger speed is at the owner’s risk, and can result in damage and premature failure. To protect the turbocharger from overspeed when operating, a speed sensor can be installed into the compressor housing to monitor shaft speed. Sensors sold separately.

Whether you’re a kit maker or an owner of a high-performance vehicle, now you can harness the power of motorsport legends and experience the durability of champions in your car with the NEW G-Series II universal Performance Turbos line from Garrett. Designed with the same quality and craftmanship that has powered motorsport legends for over 4 decades. G-Series II turbochargers are available in multiple frame sizes to suit your individual needs, whether as a complete new turbo or as a CHRA swap to upgrade your G-Series I Turbo.
G-Series II is a direct upgrade path for Gen I customers with just a CHRA purchase because the compressor housings have the same contour. This allows existing Gen I customers to use their compressor cover when upgrading.
A one-piece center housing and backplate increase durability and product safety by reducing the number of failure points associated with the turbocharger. The center housing to turbine housing V-Band connection allows for 360 degree orientation when installing with Garrett non-wastegated turbine housings.
A shorter bearing cartridge allows us to incorporate twin piston rings on both sides of the shaft wheel assembly. This will reduce the likeliness of oil leakage at the seals from the center housing to the compressor and or turbine stage.
The Inconel turbine wheel features all new G-Series aerodynamics to improve flow and boost response. The new G-Series turbine wheel flows 15-20% more than GTX and has peak efficiency up to 74%.
G-Series II and G-Series use the same turbine housings. This makes upgrades easy and cost-effective. Turbine housings are made from stainless steel to provide ultimate durability and temperature resistance up 1050 degrees C.
WARNING: Maximum allowable turbocharger speed is 125krpm. The use of this product above max turbocharger speed is at the owner’s risk, and can result in damage and premature failure. To protect the turbocharger from overspeed when operating, a speed sensor can be installed into the compressor housing to monitor shaft speed. Sensors sold separately. (click here for details)
Performance results of this product are highly dependent upon your vehicle’s modifications and tuning/calibration. The horsepower numbers represented above are calculated based strictly on choke flow of the compressor map (total turbo capability), which represents the potential flywheel horsepower.
