●About types for NEOstaight6
- Type A
In order to get stable idle and raise low-mid RPM torque, we set the duration of EX camshaft shorter.
Best suit used with stock turbine or N1 turbine.
- Type B
By giving longer duration timing than type a, it eables to raise both response and peak power at the same time, even with mid-large sized turbine.
