RB20 RB25 RB26 DET T4 Top Mount Turbo Manifold For Nissan GTR 44mm Twin Scroll

• Designed for instant spool and low-end and midrange power.
• True Merge Collector creates a turbulence-free channel for exhaust gases, promoting even pulses at high velocities.
• Applying twin-scroll divided-pulse technology allows the turbo to spool up faster and provide substantial 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.
• Flanged specifically for (2) Tial 44mm wastegates and featuring a T4 Turbine Flange, this manifold is designed for precise boost control.
• CNC Ported head flange
• Sealing surfaces machined flat ensuring a leak-free seal
