Plazmaman R33 RB25DET and R34 RB25DET NEO Full Billet Runner (to the head) Inlet manifold - 6 Injector Style.

This Plazmaman bolt on inlet plenum is designed to suit:

  • Nissan Skyline R33 GTS - RB25DE
  • Nissan Skyline R33 GTST - RB25DET
  • Nissan Skyline R34 GTT - RB25DET NEO 
  • DOES NOT FIT NATURALLY ASPIRATED RB25 NEO ENGINES - It will bolt straight on, however NA neo ports are smaller and might require porting to match the manifold, please do your own research as we take no responsibility if you attempt to install this on a NA neo RB25 Engine.

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. This manifold can be equipped with a selection of our Plazmaman billet universal or the increasingly popular Bosch Motorsport DBW throttle bodies, which can be selected whilst ordering,

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 and CNC spacers/brackets.. 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 powdercoated 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.
  • Option for SFI Spec 23.1 Burst Panel (welded to top of manifold)
  • 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.
  • 100% Made in Australia

Please Note: We also have a range of Flow matched fuel injectors available in the Fuel System Section of this online shop - these will make a great addition to your intake purchase . Any Injector you cannot see please feel free to email/contact us, as we can source them.
