Show original supplier description
The Tomei Arms Turbocharger Kit for the Nissan SR20DET engine offers a significant upgrade over traditional cast wheels. Its CNC billet aluminum compressor wheel is machined from aerospace-grade materials and features thinner blades with a larger surface area, leading to greatly improved airflow and faster turbo spool. This kit also includes a multi-rate billet actuator, allowing for customization by combining up to three springs to achieve the perfect setup. The turbocharger utilizes a ball bearing system for enhanced performance and durability. Available power applications range from 400HP to 450HP depending on the specific model (BX or MX series). Applications for this turbocharger kit include the 1991-1997 Nissan 180SX. The package includes the turbocharger, an internal wastegate (IWG), and all necessary installation hardware, including lines. Please note that supporting modifications may be required for optimal performance.
