RB30 – Single Cam Billet Inlet Manifold – 12 Injector Twin Rail

Plazmaman’s Race Bred 12 Injector, Twin Rail RB30 Single Cam Billet inlet manifold to suit Nissan’s ever popular RB30 engine was designed for tough street & race applications.

*** TWIN RAIL SETUP – One rail is on TOP of the runners and the other is on the BOTTOM SIDE – 2x 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 or the increasingly popular Bosch Motorsport DBW throttle bodies, which can be pre-selected prior to ordering. 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 and CNC spacers/brackets.

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 independent 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.

*** PLAZMAMAN also has 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 ***
