The casting manifold and wastegate from FD3S performance tuning standard HKS Full Turbine Kit are available again. Installation size is the same as the conventional to compatible with the existing full turbine kit. This is not just a reproduction; the port shape of the exhaust manifold internal was significantly reviewed to improve the exhaust air flow to the wastegate. The exhaust pressure reduction stabilizes the boost pressure even using with new GTIII turbines. Redesigning the casting material by the latest technology improves the high temperature durability. The wastegate is affordable and highly-reputed existing Special Wastegate. Using with the pipes self-fabricated for the turbine increase the fun of the large capacity turbine performance.
