he has a d16z6, the biggest u can take a d series tb is about 60. those wall are paper thin too. so i wouldnt suggest it. i would just get a tb from a b18b1, the 96-01? teg. its a direct bolt on. i have one on my d16y8, it works fine.
oh and the LS tb is 60mm, i can a b series ported to 70? not to sure. dont dont waste the money on a D series tb.
i also heard that the s2000 fits, and a h22, or f22? something along those lines. check the refrence section of this forum, or atricles, they have a list of most the honda tbs and there size.
peace out
