TR Billet Wheel GT28 Turbo for Subaru WRX 2002-2007 / STi 2004 – 2012


Regular price $1,700.00 Sale

Tomioka Racing GT28 turbocharger is the next step up from our TD06-20G turbo for Subaru WRX/STi bolt-on applications. Based on the Garrett GT28 platform, Tomioka Racing equips the already efficient GT28 with billet compressor wheel and billet wastegate actuator to further improve its performance. Tomioka uses genuine Garrett center housing assembly for reliability and performance. No shortcut is taken when producing this GT28 turbocharger. The 2.25-inch turbo inlet preserves its factory looks and will fit wide range of aftermarket turbo inlet hoses if airflow upgrade is required. The GT28 is a balanced solution for factory replacement turbo and for those who expect quick performance from the boxer engine.
