Full-Race Nissan RB26/25/20 DET(T) Twin Scroll Turbo Manifold

The Full-Race RB20/25/26 Twinscroll Turbo Manifold designed for instant spool and tremendous top end power. Applying twin scroll divided-pulse technology with long, robotically welded thickwall runners, this manifold will offer increased turbine efficiency, allowing the turbo to spool up fast and hold on throughout the powerband. Runner geometry is adjusted accordingly for the known tendency of RB engines to run slightly leaner towards cyl #6. The Full-Race twinscroll RB manifold can fit any size T4 frame turbo from S200SX, S300SX, EFR series, GT35R, GT40R, GT42R and GT45R. *GT45 requires 5" inlet compressor housing, 6" will not fit!
