Kinugawa Turbo Ball Bearing 2.25" TD05H-16K for Subaru Impreza WRX STI 98-08
Kinugawa Ball Bearing Turbocharger TD05H-16K 2.25" — Point-Milled Billet 7+7 Upgrade for Subaru WRX / STI 1998–2016 (EJ20 / EJ25)
The Kinugawa TD05H-16K features a premium Billet 7+7 Point Milling / Third-Order Free Surface compressor wheel — a significant step up from standard ruled-surface billet designs. This machining process takes 120 minutes per wheel (vs. 15 minutes for conventional flank milling) and produces a blade geometry that delivers more air pressure, better flow efficiency, and a broader power band. A direct-fit replacement for 1998–2016 Subaru WRX and STI, balanced on a Schenk MBRS 110 with a 1-Year Trouble-Free Warranty.
What Vehicles Does the TD05H-16K Fit?
- 2002–2014 Subaru WRX — EJ20 / EJ25
- 2004–2016 Subaru WRX STI — EJ20 / EJ25
- 2004–2007 Subaru Forester
- Direct replacement for TD04L WRX turbo, IHI VF30, VF35, and similar — no modification required
What Makes the 16K Compressor Wheel Different?
The 16KX (16K) billet compressor wheel uses Point Milling on a Third-Order Free Surface — the same process used in high-efficiency aerospace and motorsport turbochargers. Compared to conventional Ruled Surface / Flank Milling:
Compressor & Turbine Wheel Specifications
- Compressor Wheel: 49.5 / 68.0 mm — Billet 7+7 Point Milling / Third-Order Free Surface
-
Turbine Wheel: 56.0 / 49.2 mm — two STS options:
- 9 Blades STS — lighter, high-flow design for faster spool and broader power band
- 10 Blades STS 55 — higher blade count for enhanced flow at elevated boost levels

Compressor Housing
- Inlet: 2.25" | Outlet: 2" | Nozzle area: AR.57
Turbine Housing Options
- 7cm / AR.49 — fastest spool, ideal for street and low-to-mid RPM builds
- 8cm / AR.57 — balanced street/track option for broader power delivery
- Inlet & Outlet: Subaru single scroll | Wastegate: Internal gated
- Material: High-Ni alloy for thermal resistance
Bearing Type — STS Advanced Dual Ceramic Ball Bearing
Improves boost response by 10–15% over journal bearing designs with superior shaft dynamics control for longer service life.
Cooling & Actuator
- Cooling: Oil and water cooling
- Default actuator: 1.0 bar / 14.7 psi — custom settings (0.3 / 0.5 / 0.8 / 1.2 / 1.5 / 1.7 / 2.0 bar) available on request
What’s Included
- 1 × Turbocharger (TD05H-16K) | 1 × Oil supply kit | 1 × Water supply & return pipe kit
- 1 × Return oil pipe kit | 1 × Turbine inlet & outlet gasket | 5 × Studs and nuts
- 1 × Balance Report with Anti-Counterfeit Tag — Schenk MBRS 110 certified (Germany)
Quality & Warranty
- Brand New | Origin: Taiwan | Full dynamic balance on Schenk MBRS 110 (Germany)
Kinugawa offers a 1-Year Trouble-Free Warranty — free overhaul, recondition, or replacement if your turbo fails for any reason.
Note: Maximum power figures represent potential flywheel power based on compressor map choke flow. Actual results depend on vehicle modifications and tuning/calibration.
