Ok so I have a '94 civic ed 4dr with a b18a swap in it and a t3/t4 hybrid turbo. right now i am only running 6 pounds of boost but will probably go higher later on. I need to get bigger injectors and i am going to get an apexi safc. I was looking at just buying some used DSM injectors but now im unsure because i dont want to have to get them flow balanced and blue printed. is it worth just buying brand new RC injectors or will i save money doing dsm (after the balancing and blue printing)? does anyone have any info on doing the dsm injectors and if theirs any tweaking i need to do? and what size do u recomend? i was thinking 450cc and the most boost i will probably every run is 12lbs at the most. Thanks everyone.
