Description

Six secondary injectors on one three-rotor: the 20B build that outgrew four.

The Radium Engineering Secondary 6-Port Fuel Rail for the Mazda 20B-REW serves the big-power configuration: a high flow aluminum rail, anodized black for all popular fuel types including E85, carrying six secondary injector positions across the three-rotor's ports with a large internal bore supporting all necessary engine power requirements. The rail for 20B builds whose fueling math demands two secondaries per rotor. Injectors sold separately.

What You'll Feel

  • Fueling capacity for the three-rotor's biggest single-turbo and E85 ambitions
  • Injector duty cycles kept sane by splitting secondary flow across six positions
  • E85 volume demand met without resorting to oversized, idle-hostile injectors
  • Serious plumbing through the rail's ORB porting

Features

  • Secondary 6-port rail for the Mazda 20B-REW; six injector positions
  • CNC machined aluminum, anodized black; large internal bore; ORB ports
  • All popular fuel types including E85; injectors not included

The Details

The six-port secondary architecture exists because injector math eventually corners a big rotary, with E85's volume demand at three-rotor power levels pushing four secondaries past comfortable duty cycles or into idle-hostile sizes, and doubling the positions restores the margin: six reasonable injectors staged by the ECU instead of four monsters. Port machining and engine-side provisions must match the six-injector configuration, so confirm your housing setup and engine management strategy before ordering, with Radium's documentation and the standard four-position 20-0465 covering conventional builds. O-rings lubricated, leak check at first start, tune blended by someone who has staged a rotary before.
