hey guys i'm new to the audi scene and i bought myself a 2001 S4
i know these cars have incredible potential

i'm looking to upgrade the turbo and am stuck between the rs6 ko4 kit and the GT28 kit from ASP.

does anyone have one of these kits?
anyone with some dyno numbers or 1/4 mile times?

basically i am looking to be able to run low 11's and i dont know if the ko4's will be enough to get me there????

ASP has a gt28 kit for sale that includes fueling and exhaust anyone know anything about it?



thanks for your help guys

 

I'm running plain K04's, but if you go with either of those kits, I'd definitely set some funds aside for a big brake kit as well...you'll need a way to stop that monster.

 

have you ever had your car dyno'd
have you ever been to track with it?

 

Havn't dyno'd it yet. I have some other upgrades I'll be doing soon enough. I'll be having it dyno tuned at that point.

Been to the 1/4 mile with the car. Bad clutch prevented me from running anything better than mid to high 13's. It should be capable of high 12's with a good clutch.

That's another good point...invest in a good clutch. Skip the rs4 clutch and get something serious.

 

Check into the VAST/ARD GT kit, in my opinion you will find that the customer service and level of attention to detail put into the product are second to none. Feel free to PM me if you need more info. The RS6's are also offered at VAST, also consider a TIAL kit, either the 605 or the 650

 

VAST does offer solid customer support. I can vouch for them. Dealt with them many times.
