TPC R-Spec Turbocharger for Subaru WRX (2002–2007) and STI (2004–2021)

Description

This R Spec Hybrid, (formally known as the Red Spec) turbo comes with our popular 54.8mm billet compressor wheel and 58mm turbine wheel. 

Upgrade to our NEW 5+5 turbine wheel for better exhaust flow and less back pressure at higher RPMS. Available on in journal bearing configuration.

With our TPC clipped turbine wheel you will reach 28psi at around 4350rpm and make close to 450-500whp on E85 with supporting mods. 

TPC recommends to run the Perrin 2.4 inch turbo inlet pipe for maximum airflow into the turbo. 

Upgraded thrust components and bearing are installed in all performance turbos we build to ensure they will handle your high boost demands. Also available as a ball bearing option.

Your new power house R Spec turbo will come with an upgraded 14psi  waste gate actuator. If you don’t plan on boosting more then 18psi then let us know and we can weld the flapper shut as you will need to go with an external waste gate.
