AMS Port Injection Lower Manifold, Black | 2023+ Nissan Z VR30

The AMS Performance Nissan Z Port Injection Lower Manifold is the foundation for a port injection build on the VR30DDTT. It works alongside the factory direct injection system, and adding port injection gives a large increase in fuel capacity beyond what direct injection alone can supply.

Rather than a thin insert plate that cannot give the right spray angle, AMS built a complete lower manifold that mounts the injectors vertically for the best path into the combustion chamber. The runners and the pair of -6AN fuel rails are CNC machined from 6061-T6 billet aluminum, and the lower manifold reuses the OEM O-ring gaskets at the head. Port injection also helps keep carbon from building up on the intake valves.

The manifold is designed for Bosch EV14 type injectors and is fully ethanol compatible. This listing is the black anodized version. Injectors, fuel lines and a controller are not included: you supply your preferred injectors, build custom fuel lines and set up a controller, and custom calibration is required. AMS does not give recommendations or instructions for that custom work, and fuel system parts must be installed only by a qualified motorsport technician.
