Int. Exh. ports
 

I was woundering dose any one know the diameter of the intake, and exhaust ports on 79-83 280zxt. I was woundering if they went biger than the natraully asperated 280zx?

I am pretty sure they are, someone will correct me if I am wrong, but you also have the square ports on the turbo head.. I know mine are :D {pot/polished} :D

I think they are the same. 30mm for the intake ports on my zxt. I never measured the exhaust ports though.

Thanxs if any one has measurements pleas come forth give me all you got, or I can look it up in a boock.
