question bout injectors

im gettin a set of 450cc injectors for my civic but i have a stock fuel rail will that work ?
i dont need to get a aftewrmarket one right yet ?
or do i have to use spacers between the rail an injectors cause there taller ?
not quit sure really cuase if i do then i can get spacers an a fuel rail comin then

It depends on what type of injectors they are, there are more than one style of 450cc injectors. Are they top feed, side feed, high or low resistance. You'll also need to know the lag time when it comes time to do some tuning unless your doing and AFC hack.

high or low impedance i belive you mean. if its a ev1 connector they are usualy a taller injector, uscar or ev6 shorter and stubbier.

I am sure thse are eclipse ones that he is putting on...Yes they will fit with stock rail...But if I am correct isnt your motor stock? In my opinion way to much injector for your setup and I see no reason why you would want to run that size....Be better off running stock Integra injectors..Just my opinion though

Low impedance injectors have a faster trigger times due to the type of electrical signal pattern emitted by the ECU. This “Peak and Hold” pattern uses a high (6 amp) initial current pulse to open the injector, and then a lower current signal to keep the injector open. Since the “hold” or lower current part of the signal has created a weaker magnetic field, the injector will also close quicker.

High impedance injectors are triggered by a low (1 amp) constant current signal and kept open by the same constant (saturated) current for the entire cycle. Due to the lower current needed, less heat is generated during each cycle allowing the injector to stay cool and therefore increase its reliability. The down side is that the trigger time is decreased since there is less of an initial current to actuate (open) the injector.

and to answer about the fuel rail and all that, you may need a bigger fuel pump to juice it up, or its just gonna cut out really bad, possibly a different press regulator also? if you need higher pressure.

about 80% of the time a high impedance is needed. not very mny run low

ok ben i believe ya there but eventaully im goin nitrous an all but like jake said if i do this ill probly have to get a bigger fuel pump an different rail which i understand once u go bigger wit somethin somethin else has to change to god dam imports lol which money tight these days thats for sure i can barley afford anything to get the car done now as it is lol
but thanks for the help all

Depends on the amount of NOS that you put to it on what you will have to upgrade!!! Alot of variables...But if money is tight keep it stock and reliable...Till you are at a point in life that you can afford to fix the problems broken parts... Plus that setup will be alot of fun stock anyway especially for scca and its a great way to learn your car on the 1320 for when you are able to add more power.....Dont rush anything..Buy quality parts do it right 1st time..Will find it is cheaper in long run...Just my advice lessons I have learned

will an na setup even run with that much fuel? especially in open loop? ( which I assume will be in use alot? haha)

this may sound crazy, but just put a larger fuel jet in your no2 nozzle and that will make up for the needed fuel. might be a pita for the tuner though.

i think thats what might happen leave it stock an what not cause my buddy in wyoming run a 13.60 wit a stock ls vtec jus header an intake so thats not to bad for that set up an yes it will probly save me money in the long run if i do things right the first time around that is def agreed for that . an scca will be fun for this car for sure.
an im not sure if the na set up would run that well any ways but the bigger injectors will jus have to wait til everything an all the bugs are worked out first .
