My 91 300zx z32 twn turbo smokes a lot after it has been flogged. It only smokes after you stop it and then start it up again,
I was thinking it could bee the oxy sensor because it also stutters a bit while driving, but I just read in the forum that it may aslo be the internal seals gone crap
which will cause smoke, my question is if it is the seals would that cause it to stutter occasionally. My left turbo also leaks
oil is that a sign i need to think about upgrading the turbos? []

 

try the valve gasket seals because my car did the same thing, however, i don't own a nisssan, i'm just here cause i love to talk about them, my wife gets tired of it, so i know that you guys won't get tired of it.
