Fuel Injectors?

[97abrora]

Does anyone know what size fuel injectors the Aurora has?

I would like to upgrade them to the 550cc version. Either Venom or GReddy..

A few more questions:

There's not one fuel injector that wont fit with another car? Or am I wrong here? I went to search for Aurora parts, and I clicked on fuel injectors, and GReddy and Venom came up. For our model.

Who can install these? Where would I go to get something like this done?


Thanks,

I don't know the answer to your questions but:

Is there a problem with your current injectors? Did you do any major mods ie (heads, cam etc..)?

If the answer is no these questions then not only would you be wasting money, your performance will suffer. The car will run too rich if you just slap larger injectors on.

Are you having problems with your injectors? If so, you can probably have them rebuilt for cheaper than buying a new set.

Also, be aware flow ratings are dependent on things like fuel pressure as well as temp and such. So make sure you are comparing like ratings. 550cc seems pretty ridiculously high, though. You'd only need about 205cc/min to support 250hp at 45psi fuel pressure. 550cc/min would be enough to support about 700hp. I think all you'll do is run really rich a lot if you do this, unless you are planning on slapping some 25psi turbos on that thing or something.

Nope, no problems at all. Just thought adding bigger fuel injectors would add to the performance...


Is there anything else I can do to add more performance? Corsa exhaust system will be slapped on near December, and some new rims will be put on first week of October.

Bigger injectors without MAJOR Mods is a waste of money. You are better off doing some work on Intake and Exhaust to pick up some HPs. But really, you are driving a luxury car, if you want major performance, you need a Mustang or T/A, Z-28, a 'Vette, etc... Remember, when guys drive by in their little rice rockets that are scraping the road, you are cruising in Style and Comfort.

[97abrora]

I understand that. I am not going to use it too often, just have it available at any time.

The corsa exhaust and new intake are in the process, along with some rims.

you could always do nitrous, probably about the same price as you would spend on injectors too.

Found venom injects for $210 shipped and greedy injectors for $140 shipped.. I wish nos was that cheap.. lol

[stevensolds]

I am doing Nitrous Express EFI 50 shot. $500. I cant WAIT

That's for 8 injectors? That seems like dirt-cheap. Like reason to be skeptical cheap.

[97abrora]

I believe thats for 4...

[SupaStealth]

yeah... AC Delco injectors at the cheapest place i've seen are $70/injector

[97abrora]

210 is for 4, my mistake..

[SupaStealth]

yeah, so for an extra 80 bucks you can get some real performance

Higher flowing injectors are a waste unless there is something done to need the extra fuel, and with that big of a rating jump you need a custom computer program anyways.

The problem is that an "injector" is just an opening, the fuel pump actuall injects the fuel into the motor, the injector just provides a method to controll how much fuel is pumped into the motor. If you put on larger injectors you can get more fuel into the motor but unless you did something to the motor to improve the air flow you don't need the extra fuel.

If you did something so you need a little extra fuel then you an bump up the fuel pressure to get the extra fuel, remember the injector is just an opening and having the same opening with more pressure will allow more fuel. The problem is this is only a one dimmensional adjustment, the computer thinks in many more dimmensions than one so this adjustment is limited. If you need a larger increase in the amount of fuel then custom computer programing is needed.

Buying larger injectors is an complete and absolute waste of money on a mostly stock motor, in fact a much larger injector will cause the car to run worse. If you need larger injectors that means that you have done such crazy mods that the computer canot make the injector pusle long enough to get enough fuel into the motor, in that case you are running crazy mods and a totally custom computer programing.

Snoman hit's it right on the head. The old hot rules in the carb days do not apply here. You have to take a systematic approach. Changing one thing isn't going to get you much. If you want to change one thing to get some power you might feel is get a a catback exhaust.

I got it guys.. injectors are out of the question..

Not sure if I want rims/tires or an exhaust system first..
