The rail for 20B builds whose fueling math demands two secondaries per rotor.

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.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x Anodized secondary 6-port rail with mounting hardware\u003c\/li\u003e\n\u003cli\u003eInjectors and plumbing fittings NOT included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMazda 20B-REW three-rotor, six-secondary configurations\u003c\/li\u003e\n\u003cli\u003eStandard 4-position secondary is the 20-0465\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":43672702582851,"sku":"20-0466","price":246.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/radium-engineering-rad-20-0466-7766960242758_ea1fd339-32d8-453f-98df-f4b0f30baa6b.jpg?v=1786717277","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-secondary-6-port-fuel-rail-mazda-20b-rew-20-0466","provider":"Tuned by Shawn","version":"1.0","type":"link"}
