awd92gsx Posted January 26, 2002 Share Posted January 26, 2002 What size are the stock injectors? (forgive me, I've only owned my '77 280Z for a week) http://www.geocities.com/awd92gsx/280z Quote Link to comment Share on other sites More sharing options...
randy 77zt Posted January 28, 2002 Share Posted January 28, 2002 i heard those are 550cc -came off of injected 13b .you need to machine injector holes in manifold and build a new fuel rail for o-ring style injectors.you can get blank aluminum fuel rail and have it machined.these are like common injectors used in new cars that dont use the hose on top.i tried stuffing a oring injector in to oem zxt manifold and injector hole wasnt big enough.goto www.sdsefi and they have plans online for a fuel rail.
