Plazmaman’s Billet inlet manifold to suit Nissan’s incredibly robust TB48 engine. Designed for tough street & race applications, for Nissan’s Y61 Patrol and Chassis drag cars running this motor combo.

*** This intake manifold is designed for race use,  as the rear firewall section on a Patrol must be modified to allow clearance of the rear section of intake.***

*** We recommend this be used in conversion vehicles or modifications must be made *** 

Contact Us if you’d like application advice or further information.

Our TB48 Billet Inlet Manifold is available in either 6 or 12-injector versions. This billet inlet 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. This ensures the manifold is designed exactly how you require.

Also included alongside the manifold is a CNC machined fuel rail or rails (12-injector version), in either single feed, or dual feed. These fuel rails accept 14mm top feed injectors. All fuel rail comes with mounting hardware, including stainless steel fasteners, CNC spacers/brackets, and the required male -6AN or -8AN fittings.

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

***Some minor under manifold water line modifications will be needed for fitment – on race cars this is removed ***

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.

*** 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 can not see please feel free to email/contact us, as we can source them ***
