auxilary Posted April 1, 2005 Share Posted April 1, 2005 modifying ford 160lb/hr (yes, 1680cc/min) injector to fit mazda 13b-re secondary fuel rail. had a loose fit all the time, then i thought "hey, why not use TWO orings on the top?" ding! works like a charm, i hope it doesn't leak left: original injector, middle: mod, right: stock 550cc mazda injector that used to occupy its spot. I couldn't drill it out because that would leave walls too thin, and if I messed up, I'd be out of a modified (6an on both ends, pressure tested) fuel rail. In retrospect, I should've bought a premanufactured fuel rail that accepts those injectors... but they're over 220 bucks! Quote Link to comment Share on other sites More sharing options...

mario_82_ZXT Posted April 10, 2005 Share Posted April 10, 2005 Wow! I don't know much about rotaries, but they've always interested me. Why do you need such big injectors? Is this engine for a Z? I take it is boosted, but how much PSI? Thanks, Mario Quote Link to comment Share on other sites More sharing options...
auxilary Posted April 10, 2005 Author Share Posted April 10, 2005 rotaries have 4 injectors, and love fuel. primary 2 injectors are 550cc, secondaries are 1680cc. Stock was 550x4. primaries fire constantly, and secondaries switch on about 3500rpm. Boost is about 12psi, but not running yet Quote Link to comment Share on other sites More sharing options...
