Since you haven't said what you're after,it's difficult to recommend anything specific.
The 2.0TFSi fuel system maxes out at around 330bhp,whereas the S3's goes to about 440bhp,and the pump system below is what a few of us have used to get way beyond that.
USP Motorsports Stage 3 auxiliary Low Pressure Fuel System - USPFSIFS
Adding one of these will get you to 600bhp's worth of flow,but will do fine for anything below that.
The alternative is a Bosch 044 pump,but you need a carrier for the pump,plus a feed and swirl pot system,as it will entrain air at low tank levels otherwise.
So...what did you have in mind?
took me ages to find this thread.. wouldnt even come up on my list of latest posts!
