Hey people,

I have an A4 99 1.8TQM. I know when it comes to direct bolt on upgrades the k04 is the best thing to go with. My question is, which turbo requires the least amount of supporting mods but still provides a decent amount more power than the k04?

Can you also please state which mods the turbo will require.

There's a start, now do a little research.

 

This is in the FAQ sticky atop the B5 forum:
