FMIC.Pro intake manifold for Nissan RB26DETT 2.6L R6 CNC

FMIC.Pro intake manifold for Nissan RB26DETT 2.6L I6 CNC

One of the most advanced, high-performance intake manifolds available for the RB26DETT engine from the FMIC.Pro product line. Designed for maximum airflow, high durability, and uncompromising high-power builds. The runners are CNC-machined to increase structural strength and stability.

Conversion: Designed for converting the factory ITB (individual throttle body) system to a single throttle body configuration.

Features a welded aluminum construction with a bolt-on modular design. The plenum, runner section, and flange are separate components joined with bolts, allowing for easy disassembly, maintenance, and modification depending on the engine and forced induction setup.

The body is manufactured from high-quality aluminum, precision-welded, and CNC-machined to ensure structural rigidity and resistance to high boost pressures and operating temperatures. This solution performs perfectly in high-power setups, including applications with large turbochargers.
The intake runner geometry (intake trumpets) and plenum chamber were developed using CFD analysis, aimed at achieving uniform airflow distribution across all cylinders, reducing pressure drops, and improving flow efficiency under high engine loads.

The individually bolted-in intake trumpets help stabilize and organize airflow, resulting in more uniform cylinder filling and better utilization of the turbocharging system.
The manifold is designed for high-power RB26DETT engines, for both road and track use.
Key features:

- CNC-machined runners
