SPA Turbo exhaust manifolds are precision CNC machined from high quality ASTM 536 60-40-18 cast iron. They are ductile spheroidal castings (Nodular Iron), where the graphite components are spheroidal in shape and essentially free of other forms of graphite. Specifically designed for pressurized components and high operating temperatures. The ideal material for turbo exhaust manifolds. This manifold has a 44mm V-Band wastegate flange with a top-mount setup. The side mount turbo manifold can accept large T4 Turbochargers, will fit to the Toyota bodies.
