I have a set of skunk2 stg2 cams that im using on my b16a, i also have itr valvesprings, retainers and aem adjustable cam gears.
I will be using a comptech h/gasket (.027") and itr pistons on b16 rods.

What will be a safe limit?

I know the itr revs to 8700rpm stock, but the s2s2 cams have a more aggresive profile which i presume will put more stress on the springs and retainers.

Basically, i want to run the highest/safest revs poss (without pointlessly over-reving) whilst getting full potential of my build.

thanks
