Turbocharger Design and Specifications

A ball bearing turbocharger replaces oil-film journal bearings with angular contact ceramic ball bearings. Ceramic ball bearings operate with significantly less friction — the mechanism behind faster spool time. Dual Ceramic Ball Bearing (DCBB) designs use two separate bearing assemblies for additional support and reduced deflection under high load. Ball bearing turbos also require less oil flow, reducing heat input to the oil and the risk of oil coking during hot shutdowns.

Installation, Kit Contents, and Technical Notes

The VB670 is a genuine OEM-position bolt-on — the same oil, water, inlet, and outlet connection points as the factory turbocharger. VSR balancing ensures smooth shaft operation at the high speeds required for 670 HP. The DCBB design reduces required oil flow versus a journal bearing unit, and the larger compressor and turbine wheels provide substantially more airflow capacity than the factory unit. The free Delicious Tuning base map provides a safe starting point for the initial startup and dyno tuning session — professional tune required for full operation.

Why Choose Tomioka Racing (TR)

Tomioka Racing has been building direct-fit turbocharger upgrades for Subaru performance vehicles since the early 2000s. Every TR turbocharger is engineered around the factory connection points — oil feed, water cooling, mounting flange, and charge pipe inlet all match OEM positions — so installation is genuine bolt-on without custom fabrication. TR covers the full span of EJ-series and FA-series Subaru platforms, from the GC8 through the current VB WRX, and their turbochargers are proven in both street and motorsport use including rally racing. Each kit ships complete with turbocharger, actuator, oil pipe, water pipe, gaskets, and hardware — everything needed for the swap in one box. RallySport Direct stocks the full TR turbocharger catalog because their engineering quality and fitment accuracy are what our customers expect.

The RallySport Take

The TR VB670 is the correct turbocharger upgrade for VB WRX owners who want to push beyond the FA24WGT factory turbo capability without leaving the stock mounting location. The 54.37 mm inducer versus factory 44 mm is a substantial airflow increase matched to the 670 HP rating — VSR balanced and shipped with a free base map, ready for the tuner.
