■Features
- This turbine kit is designed to maintain the stock appearance while targeting outputs from 243 kW (330 PS) to 331 kW (450 PS).
- On a stock engine, the target output is 243 kW (330 PS), while engines with internal reinforcements can aim for 331 kW (450 PS).
- Ideal for refreshing the HKS GT turbine series or stepping up from the stock turbo.
- Designed to match the RB25DET stock turbine shape, requiring minimal modifications.
- Comes with a reinforced actuator, set to 88.3 kPa (0.9 kgf/cm²).Heat shields are specifically designed for this turbine, effectively blocking radiant heat from the turbine.
- The turbine inlet pipe is also specially designed, with larger bend radii to reduce pressure loss.
■Components
- GT III-RS Turbo (with reinforced actuator)
- Exclusive outlet pipe
- Exclusive heat shield (for turbo)
- Complete water and oil lines
- Gaskets
- Adapter pipe

■Note
- Engine reinforcement is recommended when operating at boost pressures above 100 kPa (1.01 kgf/cm²).
- Depending on the set boost pressure, it may be necessary to upgrade the injectors, high-flow fuel pump, and reinforced head gasket. Please take caution.
- When running without a catalytic converter, the boost pressure may increase by approximately 20 kPa (0.2 kgf/cm²).
- Compatibility: Early RB25DET models (e.g., ECR33) – verification ongoing
