i wanted to know whats the purpose of a aem fuel rail and also a fuel pressure regualtor. what does it help do that just buying bigger injectors wont due.
would it be beneficial to buy the fuel rail and the regulator with injectors or just bigger injectors by themselves with stock fuel rail will be better.

gets you things like this: http://www.innerauto.com/Autom..._Rail/

if you keep reading, you'll learn something ALL ON YOUR OWN.

 

they have this fourm so u dont always have to google everything.. i dont understand why everyoen has to be such a dick to anyone that has a question about something..

sorry i have no real insite to your question just im starting ot get mad that everytime i see someoen asking a question, someone else has to post a smart *** dick head answer (unless of course the questionaire deserves it)

I am not trying to start nothing with anyone or kniob or a debate about this or that.. I just dont understand why u cant either A. answer the question or B. point them in the right direction

 

it would be different if what he was asking wasn't something basic and simple... people can first get a bit of knowledge for themselves first. Then if they don't quite understand it, ask after that.

and if he's really looking for P_adams as the topic says, he could have just PM'ed him.

 

Think of the fuel rail as an intake manifold for your injectors. Basically the larger the fuel demands of the engine the larger the fuel plenum you need to feed the injectors. It's like building a water tower right next to your house; no pressure drop and you've all manner of volume available
In effect, Higher fuel demands call for high(er) flow injectors, which require a larger reservoir (rail) to pull from, which requires a high(er) flow regulator and the subsequent high pressure pump.
I make note of my saying "high pressure pump" since I assume no effort will be made to install larger diameter fuel lines, and you'll need high pressure to force more fuel (flow) thru the stock sized piping.
Although High Flow injectors will work on an OEM fuel rail, you won't be realizing their full flow potential (at high demand) without the larger rail.

damn it though, P showed me.

 

thanks mr.adams

 

a stock fuel rail will flow enough for most people, for most a fuel rail is strictly for bling...

 

i have an h22a jdm 5speed in an a 91acc,due u think its necessary to get the fuel rail,fuel pressure regulator,and bigger injectors.since im boosting in the future anyway.give me honest opinion.

 

Always Honestly, my friend. For stock N/A engines, they will not reach their full potential; and the stock set up with an adjustable fuel pressure regulator will flow more than enough.
When you go Boosted, you will need additional capacity available; and at that point the injectors and the rest come into play.
Put the money aside and get the rest when you cobble together the Turbo installation.

necessary on a boosted h22?
injectors-yes i would get some
regulator-yes i would get that too
fuel rail-only if you plan on running 500whp+
