TD06-20G Turbocharger

The Tomioka Racing TD06-20G Dual Ceramic Ball Bearing (DCBB) Turbo with Billet Wheel is a performance-focused upgrade meticulously crafted for the 2008-2014 Subaru WRX. This turbocharger aims to unleash the full potential of your vehicle, delivering a significant boost in performance for an exhilarating driving experience on the road or track. Engineered with precision, the TD06-20G features an upgraded compressor wheel and a larger 10cm2 turbine housing, which collectively allow for increased airflow. This enhanced airflow supports more fuel delivery, resulting in a substantial increase in power output. The turbocharger is built with a dual ceramic ball bearing system for durability and responsiveness. Key specifications include a 53.1 mm compressor inlet diameter, 71 mm compressor outlet diameter, 60 mm turbine inlet diameter, and 55 mm turbine outlet diameter. It comes standard with a 1.1 Bar / 16 psi actuator, with an optional 1.3 Bar / 19 psi actuator available for higher boost levels. This turbocharger is designed for specific Subaru models, including the 2008-2014 Subaru WRX, 2009-2013 Subaru Forester XT SH5/9, and the 2005-2009 Legacy GT. The kit includes the turbocharger itself, along with essential components such as gaskets, actuator, oil pipe, water pipe, and hardware kits. It's important to note that this turbo does not come with an oil pressure regulator, and the use of a Turbosmart TS-0811-0012 OPR V2 Turbo Oil Pressure Regulator is recommended for optimal performance and longevity. The choice between the 1.1 bar (16.1 psi) and 1.3 bar (19.1 psi) actuator springs depends on your desired boost levels and tuning strategy. The 1.1 bar spring is suitable for lower boost maps in the mid-teens and offers flexibility for street use or multiple boost modes, targeting roughly 18-22 psi. The 1.3 bar spring is recommended if your target boost is consistently 19 psi or higher, typically in the 22-28 psi range, potentially offering better resistance to wastegate creep in high-load situations. The maximum boost a system can consistently hold is generally around twice the actuator spring pressure, but actual safe boost levels are determined by turbo efficiency, engine condition, fuel quality, intercooling, and tuner strategy.
