Nissan RB26/25/20 DET(T) Twin Scroll EFR T4 EWG Turbo Manifold
The Full-Race RB20/25/26 Twinscroll Turbo Manifold is designed for instant spool and tremendous top-end power. Applying twin-scroll divided-pulse technology with long, robotically tig welded thick wall runners, this manifold will offer increased turbine efficiency, allowing 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.
Key Design Features
- Precision Fabricated from thick wall stainless steel
- Robotically TIG-welded construction
- CNC Ported head flange
- Sealing surfaces machined flat ensuring a leak-free seal
- Dual 44mm wastegate flanges
Note: R32 may require hood-webbing modification for the clearance of select turbos listed below:
Also, confirm that your engine mounts are not cracked or damaged, this commonly will cause the engine to tilt turbo side up.
