Performance results of this product are highly dependent upon your vehicle’s modifications and tuning/calibration.
CHRA Size
-TD05H-18G
Wheels Spec
- Compressor wheel: 50.3 / 68.0 mm (The 6+6 blades are better for low-end torque and the 11+0 type is for top-end speed)
- Turbine wheel: 56.0 / 49.2 mm 9 blades sts

Kinugawa Turbo Systems STS (Superior Turbine Strike) advanced cartridges come with dual ceramic ball bearing cages and 9 blades high flow turbine wheels improve the response speed (time needed to build boost) 10-15% as well as being more durable due to the improved shaft dynamics control. The increased power comes from the enhanced design. It utilizes an inner and outer race with rollers or balls between the two races. The inner race is pressed onto the turbo shaft, and the outer race is pressed into the CHRA. The rollers or balls replace the oil’s “job” of controlling the turbo shaft’s orientation but do still need to be lubricated but the oil restrictor had been defaulting embedded in the bearing housing to reduce oil supply more
