Tomioka Racing TR TD06-20G Turbocharger

The Tomioka Racing TR TD06-20G is a high-performance turbocharger engineered to provide significant power gains for the Mitsubishi Evolution Lancer 4-9 equipped with the 4G63 engine. As one of the largest bolt-on turbo upgrades available for this platform, it replaces factory components to support a maximum capacity of 500 HP, making it suitable for high-performance street builds or dedicated track vehicles. Technically, the unit utilizes a journal bearing system with a 52.5 mm inlet and 68 mm exhaust compressor wheel, paired with a 61 mm inlet and 54 mm exhaust turbine wheel. The turbine housing is sized at 10.5 cm², and it includes a 0.8 Bar (12 psi) actuator to manage boost pressures. While this turbo is designed as a bolt-on solution for the Mitsubishi Evolution 4-9, users should note that significant performance modifications often require supporting system upgrades, such as fuel system enhancements and engine management tuning, to safely achieve the advertised 500 HP capacity.
