i have a b16a2 bored to a 1.8 with aebs sleeves 9.1 pistons and eagle rods. the head is crower valves springs and retainers standard size. what size injectors should i run for 12psi daily and the occasional 16-18? i have 255 intank fuel pump, aem fuel reg and rail, and v-afc.

 

550s

 

550's are a nice choice, BUT it all depends on how much power you want. 550's are good for up to around 300hp.

 

550's will do 350-375 if you push em.....

get some 720's so you dont have to worry about it

 

i made 322 on 13psi with 370cc, im sure they were maxxed out but it ran good, we run 440cc, on a friends hatch he runs 13psi on a LS and it made 285WHP, 550cc would probably be your best bet, sounds like u have a nice setup, good luck
