IF I were to add injectors to my car with this set up what would I need?

Would I see any gains from doing this? Would I be getting enough air into my engine?

 

you have injectors...

be more specific..460's are plenty big for n/a...even on a big street port...

 

There is no need to upgrade or supplement the stock NA injectors unless you plan or exeeding 250hp, which will require a bridgeport. Don't worry about it. Concentrate on improving airflow by getting the mods you suggested.

 

I' have stock injectors which are 460's, How would I go about doing this I guess is what I'm asking? I figure I'd have to get a fuel rail, fuel regulator and some sort of injector control. Would I need an AFC for my car with the mods I suggested?

 

I kinda worded this thread wrong, I'm going to add two more injectors,so I'll be running 4.

 

1. Listen to what has already been said.

2. You already have 4 injectors.

 

I'm sorry, I'm going to add 2 more injectors to my now stock fuel system. That's what I'm trying to say.

 

What they are trying to say is:

1 - You don't need ANY EXTRA injectors at all

2 - Do those mods, the ones you mention, and then get a Apexi SAFC.

 

If you add injectors to an N/A it will run like ****, backfire like a ***** and get 8-10 mpg.

 

You don't need any more fuel. In fact, you will probably see some power gains by leaning it out after 5K. The stock ECU runs the car too rich.

 

Just keep on it guys.
Sooner or later he'll get the message, lol.

 

got it guys, I'm new to all this stuff. thanks.

 

The guy who rebuilt my engine put TII injectors in my secondaries and my top end rpms suck. I'm going to have him take them out on Thursday. Hopefully that will fix my problem. My gas mileage has been horrible as well. I get a Backfire any time I go over 5500 rpms.
