RB Turbo Manifold (Twin or Single Scroll)

IMR's RB turbo manifold range for the Nissan RB20, RB25, RB26 and RB30, built for instant spool and big top-end power. Choose a T3, T4, T3 twin scroll, T4 twin scroll or V-band turbo flange, with a 50mm or 60mm Turbosmart wastegate.

V-band: if you choose a V-band flange, please email us at ryan@imrfab.com with the turbo you are using so we can supply the correct flange.

Professionally back-purged and TIG welded 1.25" Sch10 stainless runners and a 3D printed stainless merge collector, with a ported head flange, improve turbine efficiency so the turbo spools up fast and holds on through the power band. Full stainless construction makes it safe to use with all race fuels.
