6Boost T4 Twin Scroll Top Mount Turbo Manifold for Nissan RB20, RB25, RB26
6Boost manufactures high-quality turbo manifolds specifically designed for the RB26DETT engine in Nissan Skyline R32, R33, and R34 GTR models. These manifolds are handmade with a unique "merge collector" design that ensures efficient gas flow to the turbine entry.
Their design reduces spool times by up to 400rpm and can yield power gains of up to 15%, as demonstrated through extensive dyno testing. Constructed from durable materials, such as thick wall mandrel bent steam pipe, the manifolds are sand blasted inside and out for a smooth finish, then coated with high-temperature exhaust enamel for heat resistance.
6Boost stands behind the quality of their manifolds with a lifetime warranty against cracking and manufacturing defects. Each manifold comes with new head and manifold studs, nuts, and a high-quality manifold to turbo gasket. Additionally, they offer a variety of flange patterns and configurations to suit different setups, including options for single or twin wastegate ports.
