Ball-Bearing Twin Scroll Turbo Kit

The Tomioka Racing TR-TS1100 is a ball-bearing twin scroll turbo kit engineered as a direct stock replacement for Subaru WRX models from 2002-2007 and STI models from 2004-2018. This kit incorporates a billet compressor wheel, which contributes to a lighter overall weight compared to competing turbochargers, thereby enabling enhanced airflow efficiency. This turbocharger kit is offered in various configurations, including a 1.3 bar turbo spring variant, though some specific variants may be sold out or unavailable. Due to the intricate nature of turbocharger installations, which involve precise oil feed and return line routing, water cooling connections, and boost line setup, professional installation is strongly recommended to ensure optimal performance and longevity. The TR-TS1100 is designed to integrate seamlessly with certain other performance components, such as the Tomioka Racing Twin Scroll High Flow Catless Downpipe (TR-ES1005), which is often sold as part of this kit or available separately for custom builds.
