I'm currently in the process of building some adaptor plates to fit a K04 off an Audi TT 225bhp too my XUD.
With the turbo fitted on, and with my pump at its cuurrent settings should produce around 160bhp. And with a few fueling adjustments bring it close to 180-200bhp
He's some pics anyway of what's been done so far...
Hopefully will have some updates later as my 20mm countersunk drill bit has arrived
Max.
