JRspec GT3071R BB is turbocharger built based on high quality NSK ball bearings (dual ball bearings, made in Japan), being widely used in tuning. Assembled in the EU with a perfectly interfitting parts made from the highest quality materials using the latest precision machines. As many as 5 stages of balancing rotors reaching 250,000 rpm, guarantee trouble-free operation even in extreme conditions with very high temperatures and recharging. JRspec turbochargers are tested in the motorsport, used inter alia in drug by Tsunami (engines 2x R30 Turbo 2x JRspec GT42R JB, giving approximately 2000 HP), in drift by Paweł Trela (engine 2JZ, turbo JRspec GTX3582R + BB, about 900 HP), Kornel Prus (engine LS7, turbo JRspec GT45R JB, more than 1000 HP) and in many powerful street cars. Used ball bearings significantly improve spool of the turbine, so the engine reacts to accelerator much briskly, reaching high torque at much lower rpm than in the case of turbines based on journal bearings – extremely useful in drift and street, where engine flexibility is of paramount importance.
