RM FD General-Purpose Exhaust Manifold (air pump specification)

Car Make: Mazda
Model: RX-7 FD3S

The turbine will be in a position where the air pump can be used, so use it when making his single turbine specification for vehicle inspection.

The turbine side is a T4 twin flange.
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
