SuperTech Dual Valve Spring Kit for Nissan 240 / KA24 (96 lbs at 34.85mm)

The JRspec GT3076R Hybrid Ceramic BB turbocharger is built on high-quality NSK ball bearings (double ball bearings, made in Japan) and enlarged by up to 3mm compared to the forged CNC compressor wheel (billet machined wheel), allowing for much more power from the engine with similar response to the standard version. Assembled in the EU with perfectly fitted parts, made from the highest quality materials using precision machinery. Up to 5 stages of rotor balancing reaching 250,000 rpm ensure trouble-free operation even in extreme conditions, with very high boost and temperatures. JRspec turbochargers have proven their effectiveness in motorsport, being used, among others, in drag racing by Tsunami (2 R30 engines, 2 JRspec GT42R JB turbos, providing about 2300 hp), in drift by Paweł Trela (2JZ engine, JRspec GTX3582R + BB turbo, about 900 hp), Kornel Pruss (LS7 engine, JRspec GT45R JB turbo, over 1000 hp) and many powerful street cars. The applied hybrid ceramic ball bearings significantly improve turbine response, thanks to which the engine reacts much faster to the throttle, achieving high torque at much lower speeds than in the case of turbines based on plain bearings, and even classic ball bearings, which is extremely useful in drift and on the street, where engine flexibility is of great importance.
