yep; there is confusion but it aint coming from me,as i said to disco before the z32 300zx didnt didnt come out with single turbo , it came out with TT or no turbo (VG30DETT or VG30DE)
the vg30det came out in the y31 cima and other luxury japanese cars
it had twin TBs on the passengers side of the engine and has the single(ceramic) turbo which i wilbe putting on my rb30det
