i have a 93 z pretty much stock and have a vortech v-1 a-trim @ 5 psi what size injectors? and could i run it stock and just bolt it up ?

 

I'd imagine you'd be safe with 24lbers, 93s have 22s so I'd look for a used set of 24s. You'll also have to get retuned for the injectors. Unless you have an fmu with the kit you need to get it tuned, it's better to ditch the fmu and just put bigger injectors anyway. You can get a much more accurate a/f than compared to an fmu.
