Turbo Concepts’ STi TCX21 is the best combination of features for achieving bolt-on 500+WHP. Ideally configured for street driveability, response, and torque, while still breathing well into the high RPM range. Routinely puts cars into 10-second quarter miles.

Each component of this turbo was hand selected by us for maximum performance and durability:

9-blade 59mm turbine is lighter and gives a torquier punch than conventional 11- or 12-blade designs.

11-blade straight TCX 71mm compressor offers a smoother acceleration and more linear flow for ease of tuning.

Higher fluid flow and thrust handling internals is a real thing, this turbo has it all.

Proven 8cm turbine housing with ideally matched td06 outflows standard TD05H models.

All Turbo Concepts performance turbos are hand-built by our senior turbo mechanic with over 20 years of experience.

Major upgrade 2004-2007 models, flows over 40% more air than original equipment VF39 & VF43 models, direct bolt up, fuel system upgrades highly recommended.

Upgrades 2008- models, flows over 30% more air than original equipment VF48 with similar spool up, will push harder in the higher RPMs than stock. More durable journal bearing design delivers more power with minimal loss in responsiveness to OE VF48 ball bearing unit.

  • 100% built and balanced in our Michigan facility.
  • Each component is checked for exact specification, proper material, and heat treatment. Other guys say “Each component meets or exceeds OEM specification” but ours really do! Only premium components engineered to outperform the factory IHI VF models are used.
  • Upgraded internals are integrated to improve oil flow and thrust handling.

OIL FEED LINE REPLACEMENT IS REQUIRED ON ALL SUBARU TURBOCHARGERS! The leading cause of Subaru turbocharger failure is oil starvation caused by clogged oil feed system. Our oil feed line sets are upgraded from factory spec to allow more oil flow to prevent clogging in the future. Required to validate warranty and will extend the life of the turbocharger!
