SuperTech Dual Valve Spring Kit for Honda NSX / C30 (80 lbs at 36.4mm)

The JRspec GT3076R BB is a turbocharger built on high-quality NSK ball bearings (dual ball bearings, made in Japan), widely used in tuning. Assembled in the EU with perfectly fitting parts, made from the highest quality materials using the latest precision machines. Up to 5 stages of rotor balancing reaching 250,000 rpm ensure trouble-free operation even in extreme conditions with very high temperatures and overboosts. JRspec turbochargers are tested in motorsports, used, among others, in racing cars by Tsunami (2x R30 Turbo engines 2x JRspec GT42R JB, producing approx. 2000 HP), in drift by Paweł Trela (2JZ engine, JRspec GTX3582R + BB turbo, approx. 900 HP), Kornel Prus (LS7 engine, JRspec GT45R JB turbo, over 1000 HP), and in many powerful street cars. The ball bearings significantly improve turbine response, allowing the engine to react to the throttle more quickly, achieving high torque at much lower RPMs than with journal bearing turbines. This is extremely useful in drift and on the road, where engine flexibility is crucial.
