Tomei Turbocharger Kit Arms MX8265 RB25DET

The new Tomei ARMS Mx-Series Turbocharger improves upons Tomei's original M-Series turbocharger design with the inroduction of a new lightweight billet wheel, multi rate billet actuator, and the very same ARMS technology Tomei is known for!

The Tomei ARMS Mx8265 Turbocharger kit for the RB25DET is a 450HP capable kit produced soley for the RB25 powertrain, providing the best bolt-on upgrade solution for any RB equipped chassis.

The Tomei M7655 works well to suit the RB's mid-range characteristics, whilst still being a good performer up towards the higher power band. The Mx8260 however, even being a bolt on application will deliver the punch of a full peak power type turbo kit.

CNC Billet Compressor Wheel

The newly designed Billet Compressor Wheel offers significant improvement over traditional cast compressor wheels. Machined from aerospace grade materials, these highly durable lightweight compressor wheels feature thinner blades with a larger surface care for significantly improved airflow and turbo spool.

Multi Range Billet Actuator

A large capacity multi rate billet actuator is utilized, with a reinforced forged billet construction. Includes a total of 6 springs for fine boost adjustments. Up to 3 springs can be combined to find the perfect setup. Swivel type nipple allows for greater freedom when routing hoses.
