Plazmaman’s Race Bread 12 Injector Single Cam Billet inlet manifold to suit Nissan’s increasingly popular RB30 engine was designed for tough street & race applications.

  *** TWIN RAIL SETUP – One rail on TOP and another on the BOTTOM SIDE – x 2 Fuel rails supplied ***

It’s visual appeal also makes a great addition to any show car. These manifolds were primarily designed for Holden’s VL Commodore, and Nissan’s R31 Skyline, however, we have supplied a number of these manifolds for RB30 converted vehicles and fitment was not an issue. Contact Us if you’d like application advice or further information.

Our RB30 Inlet Manifold can be made to suit a number of our universal throttle bodies, which can be pre-selected prior to ordering, or you can select None if you have your own throttle body. This ensures the manifold is designed exactly how you require. Also included alongside the manifold is a CNC machined fuel rail, 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). A lot of race cars would not run the IAC, as most of these cars are run by independant stand alone ECUs.

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:

  • Lightweight and rigid design.
  • Precision CNC machined billet base.
  • 3mm smooth design plenum dome.
  • Twin Rail setup – Top and Bottom of Inlet
  • Tapered RAM tubed runners.
  • Professionally Tig welded in house by our highly experienced fabricators.
  • Ergonomic appeal.
