PLM Bolt-On Ball Bearing Turbo Upgrade P660 – Subaru WRX STi 2008–2020

The PLM Bolt-On Ball Bearing Turbo Upgrade P660 is a high-performance, direct-fit turbocharger designed specifically for the 2008–2020 Subaru WRX STi EJ25 platform. Engineered to deliver massive power gains, faster spool, and long-term reliability, this turbo is the ideal upgrade for enthusiasts looking to push their EJ platform well beyond stock limitations while retaining factory-style fitment.

Featuring advanced dual ball bearing technology and a large billet compressor wheel, the P660 significantly improves throttle response and reduces turbo lag compared to traditional journal bearing and OEM turbochargers. With the ability to support 600+ horsepower, this turbo is perfectly suited for aggressive street builds, track-focused setups, and high-boost applications when paired with proper supporting modifications and tuning.

Designed using advanced CAD engineering in the USA, each turbocharger is professionally assembled and VSR balanced to ensure smooth operation at high RPMs. Unlike many upgraded turbos on the market, the PLM P660 requires no core exchange and is built using all-new castings, eliminating downtime and hidden fees.

This turbocharger is a true bolt-on replacement for multiple OEM Subaru turbo models, including the IHI VF39, VF43, VF48, and TD04 variants, making installation straightforward while delivering a massive performance increase over stock.
