Arashi TD05H-BIG16G-8CM Turbo for EJ20 & EJ25 Specifications

This Arashi turbocharger has been specially developed for Subaru EJ20 and EJ25 engines. Its power range is between 280 and 380 horsepower. It replaces the stock TD04L turbo (part no. 49377-04100, 49377-04200, 49377-04300, etc.). It features a CHRA (Central Housing Rotary Assembly) with journal bearing optimised by Arashi for superior performance.
