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.  

Note: Full-Race recommends 2000°F Ceramic Coating on our manifolds, downpipes, and turbine housings to reduce engine bay temperatures.  

KEY DESIGN FEATURES

  • Engineered using advanced CFD software and analysis
  • Precision Fabricated from thick wall stainless steel
  • Robotically TIG-welded construction
  • CNC Ported head flange
  • Sealing surfaces machined flat ensuring a leak-free seal
  • Full-Race 1-Year Warranty

Note: The Full-Race RB26 T4 Twin Scroll Manifold will not fit on a Nissan R32 with AC. This may be remedied by deleting AC, or switching to an R33 GTR AC Compressor.

  • EFR 9174
  • EFR 9180
