Mine does it over 8500, but only if I haven't hit that range for a while. It won't do it every time.

I think it's normal. I'm sure you could fix it, but would it be worth the expense? Nope.

Are you sure its not BLACK? black would indicate carbon blowing out of the exhaust. Very common if you drive with a heavy throttle at low RPMs or a earlier s2000.

Could be this ^^

My car doesnt smoke when I hit 6k (v-TAK) or 8.5k (shift point for me when racing )

I own an 01' AP1 with 92k AND GOING UP
