D16y8 intake and b18a TB?

I was told that the b18a tb will fit on the d16y8 intake. I just want to make sure, is this correct?

Is the transition still smooth? no porting or anything needed?

Re: D16y8 intake and b18a TB?

No, the bore on the b18 tb is larger, so you will have to port match the opening of the intake manifold. I want to say that the b18 is 60mm and the d16 opening is 56mm, but I may be wrong. I just put an h22 tb (62mm) on my z6 IM, and it took probably an hour, maybe a little less, with a dremel. It would go a lot faster with a grinder or a dremel with a bit that was made for aluminum (mine was not)
