HKS has developed this Extension Kit specifically for use with RB26DETT engines equipped with HKS GTIII Sports Turbine Kits: the GTIII-SS Sports Turbine Kit, GTIII-RS Sports Turbine Kit, and GTIII-2530 Sports Turbine Kit.
The lost-wax casting method and stainless steel construction allow for a highly efficient, extremely durable product where both factors are needed most. The port matched inlets and 70mm outlets provide the perfect balance of low end torque by maintaining exhaust velocity, while allowing for sufficient flow at high RPM .
In-house testing has shown 25 horsepower gains (from 520 to 545 horsepower) between 5000 RPM and 7000 RPM.
Product Code: 14018-AN005
