basicaly i like my 1.8t quattro sport but its a bit slow even with a chip and about 200bhp. i fancy putting a t28 on some day but then its the hassle of a new custom downpipe etc and getting it chiped to run properly. i would think you can get a realistic safe 300bhp this way but with the price of s4's getting less all the time is it worth the hassle when you can buy one with a simple chip and have 300bhp with no hassle? how many people are running a t28 set up?
