Description

Plazmaman GTST R33 and R34 NEO head Full Billet Runner (to the head) Inlet manifold – 12 Injector Style. 

The engineers here at Plazmaman Australia headquarters had only one thing in mind when they designed the Nissan RB25 Inlet manifold – to release a premium quality item that ticks all the boxes. Plazmaman inlet manifolds utilize some of the most advanced manufacturing techniques. Multi axis HAAS CNC machines ensure that all the one piece billet bases have tolerances to within .005. The inlet manifold dome utilizes a hard temper 3mm sheet alloy surface that has been made to shape in house with advanced forming techniques.

Our RB25 manifold is designed as a standalone manifold, so the factory Over the rocker cover Inlet is totally removed, and this manifold is bolted directly to the cylinder head using a single throttle body operation to maximize airflow. The manifold can be designed to suit a number of our universal throttle bodies, which can be selected whilst ordering, or you can select None if you have your own throttle body. This ensures the manifold is designed exactly how you require.

An added feature of these manifolds is that they can be ordered and manufactured specifically to suit 6, or 12 injector operation. For both options, we include one of our CNC machined fuel rails, in either single feed, or dual feed. Both of these fuel rail styles accept 14mm top feed injectors. The fuel rail comes with all mounting hardware, including stainless steel fasteners, CNC spacers/brackets, and the required male -6AN or -8AN fittings. Our billet manifolds are offered with, or without a provision for the factory IAC (idle air controller) to be used remotely.

This Plazmaman Inlet now also comes with a special designed under inlet WATER RAIL. This ensures that the water flows through the head back to the radiator exactly the same way Nissan Intended it to. This is the only aftermarket inlet manifold on the market that has this feature and we guarantee zero air locks if plumbed exactly as Plazmaman advises. 

These manifolds can be supplied in 3 finishes, Raw, Polished, or powercoated Black, for the stealth look.

As with all Plazmaman inlet manifolds, these are packed with many features such as:

  • Built-In Ram Tubes
  • 6061 T65 Aluminium.
  • 6 or 12 Injector options
  • O-ring port seal design.
  • Precision CNC machined billet base, with hand made 3mm smooth design plenum dome.
  • Professionally Tig welded in house by our highly experienced fabricators.
  • Ergonomic appeal and lifetime structural guarantee.
