Nissan RB26 25 20 DETT Twin Scroll EFR T4 IWG Turbo Manifold

Let Your Turbos Spool Faster With the Nissan RB26/25/20 DET(T) Twin Scroll EFR T4 IWG Turbo Manifold

The Full-Race RB20/25/26 Twinscroll Turbo Manifold is designed for use with BorgWarner EFR 0.92 a/r turbos. Applying twin-scroll divided-pulse technology with long, robotically tig welded thickwall runners, this manifold will offer increased turbine efficiency, allowing the turbo to spool up faster and provide power gains throughout the entire powerband. Runner geometry is adjusted accordingly for the known tendency of RB engines to run slightly leaner towards cyl #6.
