Extension kit with a good balance between performance and durability brings out the maximum potential power of the GT III turbine.

The lost-wax casting makes high-durability.



The single port inlet matched to the stock turbo of RB26.

【Features】

• It does not only improve exhaust efficiency but also product durability.
• The extension kit balances the two opposing sides of tuning it prevents torque decrease at low-rpm caused by expanding the airflow and reduces the secondary exhaust pressure at high-rpm.
• This extension inlet is a single port matched to the stock turbo of RB26, and the outlet diameter is φ70mm.
• Durability is improved by processing heat resistant stainless steel using the lost-wax casting.

【Performance】

Note: This Output and Torque data were measured by HKS. There are some differences depends on the measuring equipment or the vehicle.
