20psi on 450cc injectors, has been done, but it takes a better pump and more fuel pressure ( about 50-52psi) to do it,

that duty cycle on those injectors is wayyy wayyy more than what it should be, dont halfass fuel setups like that. Youre gonna need a walbro fuel pump and bigass injectors at least

Re: 20psi on a b16

ya dont go 450's becuase someone says it can be done. because you can buy 750's for just a little more i got rc750's for 350 shipped for high saturated. and my 450's were precision and cost 275 or somethign shipped. its always better to be on the safe side.(well if you want your car to last longer that is) and like stated get the fuel pump there only 100 at the most.

Oh yes, It's not good, but doable

I'm doing 350whp on a DOHC ZC with Percision 680cc, Walbro 255, Adj. FPR. yadayada
