New for 2018 - Tomei ARMS MX Series Turbocharger

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 MX7960 Turbocharger Kit includes turbocharger, and all associated gaskets, lines, and hardware needed for install on your SR20. This turbocharger kit is rated for an approximate 450HP, depending on supporting mods.

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.
