Garrett G38-1000 Turbocharger

The new G-Series II G38-1000 Garrett turbocharger

G-Series II compressor technology, inconel turbine wheel, rated for up to 1000 HP

The Garrett G-Series II G38-1000 was developed for high-performance turbo and motorsport applications and combines advanced G-Series II compressor technology with Garrett's proven quality and durability.

The optimized compressor aerodynamics enable higher pressure ratios and support increased boost levels. At the same time, high flow efficiency delivers cooler, denser charge air, helping to maximize the engine's performance potential.

The G38-1000 is suitable for engines with a displacement of 2.0 to 5.5 liters. The high-temperature-resistant Inconel turbine wheel features a 66 mm exducer. Depending on the application, stainless steel turbine housings are available with V-Band or T4 Twin-Scroll inlets and various A/R ratios.

• 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
• Integrated, fully machined sensor port for precise turbo monitoring & tuning
• Lightweight aluminum backplate to reduce turbo weight
• Inconel turbine wheel with 74% increased efficiency
• Stainless steel turbine housing resistant to temperatures up to 1,050°C
• Turbine housing with V-Band or T4 Twinscroll inlet and V-Band outlet
• V-Band CHRA connection for full rotational adjustment
• Dual ceramic ball bearing system
• 4 water connection options
• Dual piston ring sealing
• Some G-Series GEN I and GEN II turbocharger versions are available in standard and reverse rotation

GENERAL DESCRIPTION OF THE GARRETT G SERIES TURBOCHARGER

Whether you are a manufacturer or owner of a high-performance vehicle - now you can harness the power of motorsport legends and experience the durability of champions in your vehicle! With the new G-Series II Universal Performance Turbo line from Garrett, you get state-of-the-art turbocharger technology. These turbos have been developed with the same quality and precision that has driven motorsport legends for over four decades. The G-Series II turbochargers are available in various housing sizes to meet your individual requirements - whether as a completely new turbocharger or as a CHRA replacement to upgrade your G-Series I Turbo.
The latest generation turbochargers from Garrett are the evolution of the GEN I series. More efficiency and more features are included here. In addition to significantly higher airflows with the same wheel size and extremely high temperature resistance in the turbine wheel and housing, the chargers come with features with 4 water connections, double piston ring sealing, and preparation for the speed sensor.

Right and Left Rotating:
The absolute novelty of the GTX Gen II turbochargers has naturally been adopted in the G-Series. The G-Turbos are also available as REVERSE rotating chargers!

Compressor Wheel
All G compressor wheels are CFD designed, forged, and milled from special high-strength aluminum alloys. The new G-Series II compressor wheels achieve 10% more airflow than the Gen I compressor wheels.

Compressor Housing
The new aero-optimized high-flow compressor housings with integrated mount for optional speed sensors are matched to the new G-Series compressor wheels. The improved recirculation systems from Generation I have been adopted in the G-Series II and significantly extend the operating range of the compressor by shifting the surge line.

Core Assembly
All Garrett G are equipped with water cooling with 4 connections. This allows two connections to be selected on each side. This greatly facilitates the installation of the water lines. And the G-Series II naturally comes with a double ceramic ball bearing like the Gen I. New is the double piston ring sealing on both sides.

Turbine Wheel
The new turbine wheels are made from the high-performance material Mar-M. This material easily withstands exhaust temperatures up to 1050°C. Here too, with the same wheel dimensions, 15-20% more throughput compared to the GTX turbochargers.

turbine housing
The turbine housings are cast from a special stainless steel alloy which also withstands up to 1050°C.

If this turbocharger is not marked as in stock with us, it may still be that we have the individual components in stock and can assemble the turbocharger for you. Please call us or send an email to check if the turbocharger is possibly available from stock.
You can also inquire whether shorter delivery times than stated are possible, as this often depends on the right timing of the order.

Individual Garrett Turbos

This turbocharger offered here comes directly from the manufacturer. However, with Garrett turbochargers, there are various options to adapt flange patterns and connections to the conditions in your vehicle. We are happy to assemble Garrett turbochargers with various turbine housings and compressor housings for you. Please contact us by phone, email, or contact form.
