Collection: Kinugawa Turbo for EVO 1-3 DSM with 3" Anti-Surge Covers

3" Anti-Surge Turbo Upgrades for 4G63T EVO 1-3 & DSM

High-flow turbocharger upgrades with 3-inch ported shroud (anti-surge) compressor covers for Mitsubishi 4G63T engines. Eliminates compressor surge at high boost levels while maximizing airflow for Lancer Evolution I-III, Galant VR-4, and DSM Eclipse/Talon builds.

Why 3" Anti-Surge Technology

The 3-inch ported shroud design bleeds excess pressure from the compressor wheel, preventing surge at high boost and RPM. This provides 44% more airflow capacity than stock 2.5" covers, wider efficiency maps, and safer operation at aggressive boost levels above 1.5 bar (22 PSI).
