Can I use other Audi fuel injectors that are bigger? What I mean to say is , say I have a older Chevy Malibu with a 350 cu.in. engine and a two barrel carburetor. Could I use the four barrel carburetor from a Chevelle 350cu.in engine?
I have a 2007 A4. Would this even work. I'm new to computer operated motors..
Thank you

The answer is yes in some cases, we often use larger injectors from other models when building a car for more power.

Having said that there would be no performance advantage to be had until there is a need for more fuel than your standard injectors can provide. In almost all cases the stock injectors can provide all the fuel needed with the stock turbo and same would be true if you have a naturally aspirated motor. If you have a turbo motor it is possible to purchase a more aggressive tune, that will raise the boost and turn up the fuel without having to touch the engine. The tune takes 5 min to load via a cable and a laptop.

Completely different world with electronically controlled motors that are much more sophisticated. When you make changes to the motor, like larger injectors etc, you have to re-tune the car to account for the larger injectors.
