The new Tomei ARMS BX-Series Turbocharger improves upons Tomei's original M-Series turbocharger design with the inroduction of a new ball bearing, lightweight billet wheel, multi rate billet actuator, and the very same ARMS technology Tomei is known for!
The Tomei ARMS BX8265 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.
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 Rate 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.
For more information about actuator setup, see Tomei's video HERE.
