alright i've been thinkin about it, and i'm not gonna be running a turbo no more...things change. well anyway, i'm gonna be running the gas instead to kinda save money and just use it on the track and this will also cut back on my risk of gettin in trouble since it won't be constant power. well anyways i was wondering with nitrous which cam could be used a stg. 2 n/a or turbo cam. i don't want just the stage 1 cause it seems like it wouldn't be enough since i still wanna try and get as much out if the motor i can for the track. what about a custom ground? are they as strong as the cast cams? or is it just the regrinds that are weak? thanks for any help guys. oh and i'll be using a z6 cam for my d15b.
