Product Description

The Garrett 934075-5002S G25-700 G-Series II Supercore is a high-flow turbo core designed for aftermarket and motorsport applications. It offers enhanced aerodynamics over the earlier G-Series I line, delivering up to ~10% more compressor flow at peak conditions. Its standard rotation "Supercore" layout makes it suitable for custom turbo builds where flexibility is needed in housing and plumbing choices.

With its 54 mm inducer and 67 mm exducer compressor wheel, and a matching 54/49 mm turbine setup, this unit supports builds between 350 and 700 hp (for engines from 1.4 to 3.0 liters). The center section is oil and water cooled to sustain performance under heavy loads and thermal stress. As a modular core (Supercore), it must be mated with a suitable turbine housing, manifold, and proper calibration to work in a real engine system.

This turbo core is ideal for experienced tuners, kit builders, and custom forced induction systems. It is **not** intended as a plug-and-play OEM replacement, so proper fabrication, alignment, and tuning are essential for safe operation and peak performance.
