Kinugawa Turbo 3" TD05H-20G — High-Flow Upgrade for Mitsubishi 4G63T
The Kinugawa TD05H-20G is the largest-displacement turbocharger in the Kinugawa TD05H EVO series, purpose-built for the Mitsubishi 4G63T engine platform. Featuring a 3" anti-surge or non-anti-surge compressor cover and a larger 8cm / AR.57 turbine housing (vs. 7cm on the TD05H-16G and 18G) with Mitsubishi single-scroll inlet and 4-bolt outlet, this turbo is engineered for DSM 1G/2G and EVO 1–3 builds pushing maximum power potential.
⚠ Important: The 3" compressor housing requires modification to your intake system or coolant tubes for proper fitment.
