There was a chap in Newcastle AU who turbo's the 2.2L GTI engine fairly well. Again not running a great deal of boost. He had custom manifolds made, but expect to do that anyway, he found higher flowing injectors that he swapped out the originals for, and from memory he ran a simple Haltek ECU
Long story short, find a keen exhaust dude / mechanic and he'll happily take your money of you
#edit. how quick the memory fades. This was the chap I was thinking off
