    I found some RC 650's for cheap and plan on doing an 18g with fmic, cobb tuned. Are these big enough/too big. What should I look for with used injectors? Thanks...

    i think those are big enough. i use sti pinks with my 18g setup. dont forget you will need a fuel pump too, like a walboro.

    Ya, with my 18g I am running 21-22psi and my idc's are right around 90% or so (630cc). At a minimum I would go would be the 650's. Sorry, but pinks on a 18g (or anything other than the stock turbo) is kinda a waste.

    650s should be fine for your application
