The JRspec GT3071R BB turbocharger is engineered with high-quality NSK dual ball bearings, made in Japan, and is widely used in tuning applications. Assembled in the EU, it features perfectly interfitting parts crafted from the highest quality materials using the latest precision machines. The turbocharger undergoes five stages of rotor balancing, reaching up to 250,000 rpm, ensuring reliable performance even under extreme conditions with high temperatures and recharging demands.

JRspec turbochargers have been tested in motorsport, including drag racing and drifting, and are used in powerful street cars. The dual ball bearings significantly enhance the turbine spool, allowing the engine to respond more quickly to the accelerator, achieving high torque at lower rpm compared to turbines with journal bearings. This feature is particularly beneficial in drift and street applications where engine flexibility is crucial.
