Plazmaman R32/33/34 Skyline GT-R RB26 Full Billet Runner (mounts direct to the head) Inlet Manifold – 6 Injector Style. 

The engineers at Plazmaman Australia headquarters had only one thing in mind when they designed the Nissan RB26 Inlet manifold – to release a premium quality item that ticks all the boxes. These 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.

The RB26 manifold is designed as a standalone manifold, so the factory 6 individual throttle bodies are removed, and this manifold is bolted directly to the cylinder head using a single throttle body operation is used to maximize airflow.

The manifold can be built for and supplied with a number of the universal billet throttle bodies or the increasingly popular Bosch Motorsport Drive-By-Wire units, which can be selected prior to 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,  one CNC machined fuel rail is included, 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. Plazmaman billet manifolds are offered with, or without a provision for the factory IAC (idle air controller). On the RB26, a remote mounted IAC is offered, to allow the factory IAC to be compatible.

This 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 Plazmaman guarantee zero air locks if plumbed exactly have Plazmaman advises you to. 

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.
  • Precision CNC machined billet base, with hand made 3mm smooth design plenum dome.
  • Professionally Tig welded in house by highly experienced fabricators.
  • Ergonomic appeal and lifetime structural guarantee.
