The JRspec GTX3071R+ JB (GTX3077R) turbocharger is engineered with high-quality NSK dual ball bearings, made in Japan, and features a 4mm enlarged forged CNC billet wheel. This design allows for significantly larger engine capacities while maintaining a spool similar to the standard version. Assembled in the EU, it uses perfectly interfitting parts crafted from the highest quality materials with 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.

JRspec turbochargers have been tested in motorsport, including drag racing and drifting, demonstrating their capability in high-performance environments. The use of ball bearings significantly improves the turbine spool, allowing the engine to respond more briskly to the accelerator and achieve high torque at lower rpm, which is crucial for drift and street applications where engine flexibility is essential.
