B17A exhaust manifold on a B18A??

I am pretty sure they are the same, and I did a search in this forum, but does anyone know why a shop that did custom turbo manifolds would have a different listing for the B16A, B17A, and B18A/C? I was under the assumption they all had the same exhaust mounting flange. The funny part is the B17A flanged manifold was $50 cheaper… Can someone please verify this for me.

Thanks,

well, full-race motorsports has a b-series manifold that fits all b-series applications. i’m going to go off the deep end and assume geoff knows what he’s doing, so you’re pretty safe to assume that all b-series EXHAUST flanges are the same.

I actually have a B18A but I will go ahead and order the B17A manifold. Save myself $50…
