The K04 on the 1.8T won't really lag anymore than the K03 will.  It'll just extend your usable power band by about 700-1000 rpm.  In my mind, Audi shouldn't have farted around with the K03 at all for the A4/S4, it's clearly too small a turbo for the motor, they should've just used the K04 to begin with.
