Default help me pick injectors

setup....
dohc zc
greddy15g kit
jrc intercooler,2.25 in piping
hallman mbc
walbrow255,b@m fpr and lots of other stuff i dont feel like trying to remember

Im running 7lbs tuned on crome and im going to remove the exhaust and run a dump and i want to raise the boost to 10lbs fot the rest of the fall untill the car goes away for winter and i redo some things this next spring(manifold,downpipe and full 3in) Im running stock injectors now and my tunner says there maxed out

here inlies the confusion...i was told the stock ones are 240s.
here are some options off the top of my head;
dsm440s with resistor box
prelude/accord (340?) with resistor box
used rc 310 from greddy kit
or paying out the *** for some rc's brand new
Also, how do i identify which honda injestor is which,are there numbers on them?a shop owner here in town has a box full of random honda injectors and he said i can go though it, but he doesnt know which are which..thanks,sorry for the long post

Thats what I did... but im on a stock motor and already at 63% duty cycle... Think I will need to go bigger after my build


DSM 450's will be fine for you.

IMO get some tunertoys injectors. THey drop straight in without any extra boring or wiring and are BRAND NEW. Also flow balanced wiht 1% tolerances.

200 bucks new..i'd say good dela

the short answer is high impedience is what most of our cars run. Low impedience you would need to use a resistor box. also described as 'saturated' or 'peak and hold'

do a serch for the technical difference

adictionbass's post may have confused some people. Just so there isn't any confusion:

saturated is another name for high impedance injectors

peak and hold is another name for low impedance injectors

If you are running a peak and hold injectors make sure you install resistors or a resistor box. The reisistors need to be installed so that you dont fry the injector drivers (fry your ECU) or that you dont fry the injectors themselves. The injectors may or may not run without a resistor box/resistors installed. But sooner or later you'll fry the injectors/ECU cause they are getting too much voltage or current (I can never remember which one, but I think it's voltage).

Bigger the better. If you dont have a choice, and to choose between those two. Get the 550cc
