Is a fuel rail + injectors needed
 

So my setup consists of i/h/tp/e currently

within the next month or so i'm going with a larger throttle body, hondata intake manifold gasket, aem ems, clutch/lighter fw ( if it matters)

would I benefit from larger injectors?

no you will not see any gains, you dont need new injectors untill you get serous with na mods(ie big cams, big comp pistons), turbo or nitrous

No, It is not necessary with your setup.

Thanks guys.
