How can i get as much air in my engine with out turbo just bolt on's?
 

Just got 725cc fuel injectors and I'm trying to get as much air in the engine as possible with just bolt on's, I currently have Gen 3, testpipes, and lightweight flywheel. what else should I get to get to get the air I need? and is 725cc fuel injector to much for my car? and how exactly do fuel injectors work? and how much more power will they give me if I give it the air it needs?

omg i hope your trolling...

unless you are have force induction you wont need bigger injectors.

if you want more air into your motor, get a larger throttle body, port and polish the intake mani and heads, oversized valves, bigger cam shaft, and test pipes.

And lighter crank, rods and pistons so you can run higher rpm than stock.

The truth is that bolt-ons will not make any appreciable difference in the power output of your engine. You're wasting time and money making the changes you've proposed. Step back and spend some time and effort to learn more about automotive performance.

The amount of air a naturally aspirated engine can move is limited by its displacement. If you want to get more air into your engine without a blower, you can try a stroker kit, but it will cost more and be more complicated to install than a turbo or supercharger.

Plug in a few hair dryers into your intake

And rpm. Of course, if you raise rpm, you'll need a cam that can accomodate the new air flow potential.

Not a good idea imo. I habe bolt ins and a tune. The more air you pull into your engine, it will jump into limp mode. You will need a tune to fix the air flow ratio.
