JWT has released the first performance camshafts available for the 2007+ VK56DE, which incorporates intake cam phasers for a much broader torque curve. The ability to gain over 26 WHP and still maintain a wide torque curve is owing to JWT’s years of development on Nissan VQ35 V6, which has always used intake cam phasers. This new VK56 engine has a mass flow balance that allowed JWT to design the new CS2 profiles to run safely to 6500 rpm (well beyond peak power) with only a spring upgrade on the intake side. 252I/256E DEG. .438" (11.13MM) I / .430 (10.90MM) E LIFT. JWT SPRINGS REQUIRED ON INTAKE SIDE.
