The JRspec GTX3071R+ JB (GTX3077R) turbocharger features high-quality journal bearings and a 4mm enlargement compared to the standard version. It is equipped with a forged CNC billet wheel, allowing for significantly larger engine capacities while maintaining a spool similar to the standard model. Assembled in the EU, it consists of perfectly interfitting parts made from the highest quality materials using advanced precision machinery. The turbocharger undergoes five stages of rotor balancing, achieving speeds of up to 250,000 rpm, ensuring reliable operation even under extreme conditions with high temperatures and recharging.

JRspec turbochargers have been tested in motorsport applications, including use in the Tsunami drag racing setup (2x R30 Turbo with 2x JRspec GT42R JB, producing approximately 2000 HP), and in drift racing by Paweł Trela (2JZ engine with JRspec GTX3582R + BB, around 900 HP), as well as Kornel Prus (LS7 engine with JRspec GT45R JB, exceeding 1000 HP), among many powerful street cars.
