I have for sale a S5 turbo lower intake manifold ported to match a 6 port N/A 13B. It has been ceramic coated silver. It is missing one fuel injector diffuser. I am including a new upper intake gasket. I was going to put this on a 6 port block so I could use the stock turbo manifold but I went a different route. This is perfect for turbocharging a 6 port normally aspirated engine. The port work is very clean and smooth. The transition on the runner bends is smooth. I pressed brass fittings into the manifold for vacuum reference ports. A block off plate was machined and placed over the pressed nipples and JB weld was used to make sure no leaks occurred in the future. This manifold will fit any 2nd gen 13B engine. $100 shipped paypal ready
