Description

The Tomei ARMS MX8265 turbocharger kit (TB401A-NS06A) is designed as a direct bolt-on upgrade for the Nissan RB25DET. Featuring a lightweight CNC-machined billet compressor wheel and a high-temperature alloy turbine, the MX8265 delivers faster spool, greater airflow, and improved efficiency across the rev range. With its journal bearing center section, the turbo offers reliable performance and smooth boost delivery, while the billet actuator with interchangeable springs allows for precise boost control. Capable of supporting around 450 horsepower with the proper supporting modifications, the ARMS MX8265 is ideal for enthusiasts looking to maximize the potential of their RB25-powered Skyline with a responsive, durable, and track-proven turbo upgrade.

Features:

  • CNC Billet Compressor Wheel – Improved airflow and faster spool-up.
  • Journal Bearing Center – Durable design with a smooth boost curve.
  • Multi-Rate Adjustable Actuator – Spring-tunable for precise boost control.
  • Optimized Housings – Efficient flow and stable high-RPM performance.
