RM FD3S HKS TO 4Z Turbine Kit Exhaust Manifold

Car Make: Mazda
Model: RX-7 FD3S

Please use it for repair when the exhaust manifold of HKS TO4Z turbine kit for FD3S is broken .
Since the turbine side is a T4 twin flange, it can be used as a general-purpose product.
The turbine position and waste gate (WG) position are exactly the same compatible products.
The piping to the WG is designed so that the exhaust flow is smooth, which makes it easier to open the WG and prevents the exhaust pressure from becoming too high .
The pipe diameter is 60Ф from the engine, squeezed to the turbine side, and 48.5Ф is sheet metal shaped into a square pipe.
It has the effect of increasing the flow velocity by making it thinner gradually.
The flange is 15mm thick on the engine side and 12mm on the turbine side, so it is designed to withstand heat distortion.
