TX Fuel injected vs Carburated

Im thinking of switching my s4 from a fuel injected set up to a carburator. Are the 5-6 ports still going to be usable? Where can i get the best kit?

Why do you want to downgrade your fuel system?

To keep the aux ports, you must retain the lower intake. That limits the carbs you can use to basically a Weber side draft style. However because half the intake is now missing, you aren't going to see as much benefit from the aux ports as you once did and you're going to lose torque no matter what.

Unless you are running in a racing class that requires a carburetor, stick with EFI.

And I don't think I even need to mention that this has been covered 10,000 times before...

Agreed, search the forums. This is a commonly asked question.
