I need a Turbo for a 99 a4 1.8t AEB

[PsorianoPre99A4]

Anyone of have suggestions of where I can get a turbo? I want anything better then the stock Ko3 it comes with.

Better then stock for power or reliability? Power would be a ko4 but many will say your wasting your money and not worth it. Reliability can't be beat with the Borg warners. Another option is the frankenturbo, a ko4 hybrid that will require a few more parts to run properly. Search all of this and come to a conclusion. This is just a basic over view of what your looking at. There's way more options then you think.
