i was getting ready to replace some old b16a1 injectors. i was thinking of getting a set of RC 270CC injectors, since i'm mainly running bolt-on upgrades, i.e.: header, exhaust, intake manifold/throttle body, fuel rail, etc. i was wondering if anyone knows what the flow rate of the stock b16a1 injectors is?

 

i think all b series motors run 240cc injectors but double check that info.

from the mods you have listed you do not need to upgrade to larger injectors. maybe if you plan to boost, but if you got larger injectors with your current setup, you would simply need to run a chip to cut back on fuel. (thats a lot of money to get you right back to the same place) spend your money on cleaning the ones you have unless you plan to boost.

 

b16's are 240 cc peak and hold...same as d16a6 injectors

 

all b series vtec are 240.

You won't need 270s for bolt ons, and stock fuel rail will work no matter what, i've yet to see a street car "need" one.

 

thanks 4 the info. the only reason im getting the bigger injectors is because im planning on buying a stage 4 ported head with oversized valves, racing cams, big bowl work, etc. eventually im gonna get his 2.1L b16a1 block with 15:1 compression as well........when i get about $4000.

 

15:1....? damn o.0 dont know if ive seen anyone with 15:1. and thats a big b16
