SUBARU GTX3071 — BALL BEARING PERFORMANCE TURBO

GTX Re-Engineered for Subaru Performance.

MAX1 takes the GTX3071 concept further with a high-performance ball bearing center system, our own redesigned GTX compressor aero, and purpose-designed turbine housing options — creating a complete performance turbo engineered specifically for Subaru.

BALL BEARING CENTER SYSTEM
The high-performance ball bearing core is engineered for reduced rotational resistance and sharp, responsive spool.

MAX1 REDESIGNED GTX AERO
Our forged billet compressor wheel features a redesigned blade and aerodynamic profile to improve airflow and performance beyond a conventional GTX-style setup.

7 / 8 / 10 cm² TURBINE HOUSINGS
More compressor flow needs the right turbine-side flow. Choose from three housing sizes to match your performance target:

7 cm² — Fast response & street performance
8 cm² — Balanced response & top-end flow
10 cm² — Maximum flow for higher-power builds

SUBARU DIRECT BOLT-ON
Retains the Subaru-style triangle turbine inlet flange, providing a direct bolt-on configuration for compatible Subaru applications.
