i have an rb25det neo with a hks28/35kai. Its now time to upgrade the cams. i have been looking ansd some tomei poncams, but im not sure which ones i will need. Im hopefully after 300rwkw, its a street car but hopefully in the future ill do some track work.
Anyways there is 2 differnt types of cams. Not sure if i need type a or b? cheers
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.
