T440M TURBO KIT for RB25DET
TURBO CHARGER
Seamless power straight to the high RPM range that a stock turbo boost-up can't reach!
Refined the balance of the housing, turbine wheel and the wastegate actuator to make RB25 even more enjoyable and user-friendly compared to the previous model.
While improving low-to-mid-range response, also focused on enhancing mid-to-high RPM characteristics, where the stock turbo is known to fall short.
The all-new billet compressor wheel further optimizes spooling efficiency.
