my friend is selling me a set of 990cc injectors(low impedence) for $250 new. he says he needs the money, are these to be for a b18b daily driver turbo?

 

those are too large for your app. what type of fuel management do you have?

 

what are you using to control them?

 

nothings too big if you can get it to idle

 

My thoughts exactly. What kind of fuel management are you running?

 

a zydne gold secu, but my turbo set up is not done yet.

 

keep in mind you need high-impedance, unless you have a resistor box or something else to control them.

 

oh i forgot to ask, whats the deal with the impedence? i don't have a clue on it.

 

it's basically the voltage/pulse width on the injectors. your civic is high impedance and it will not work without a resistor box which is basically an amplifier.

 

here's a link to some popular injectors and the flow rate. http://www.allmotorhonda.com/techpages/injector.htm

 

saturated injectors = high impedence; peak-and-hold injectors = low impedence

to run low-impedence injectors on a car that originally came with high-impedence injectors, it is necesary to run a resistor box of some sort, or you will fry your ecu. lots of old hondas came with resisotrs boxes and they can be had for really cheap...just take a look around here and you will find one.

and yes, what are your HP goals? 900cc is probably too big for you...unless you are shootign for 600-700 hp.

 

300whp is my goal, i wanna run 15psi.

 

get your head ported and polished w/ intake mani and you should have 300whp with 11-12psi with good tunning.
There are 550cc-720cc injectors for $200-$300 all over thepartstrader.com, just do a search.

 

oh one more question, would it be better to use a msd 6BTM or a msd 7AL-2

 

the 6 is more for street performance and the 7 is drag and for pros. just keep it simple with the 6 since you aren't seeking tons of power.

 

or you could save your money and keep the stock ignition. i have heard of many ppl upwards of 400hp w/ stock ignition...u need the right plugs gapped correctky of course...

 

Don't upgrade the ignition until you need to or you run into trouble. Of course, I'm not familiar with Zdyne at all so..

 

Viren(b18bturbo) has MSD injectors on group buy for $250 a set, they come in 65# and 72# sizes. You just need to pick up a resistor box and you'll be good...
