Same goes for the xuds, or most engines pushing 2.5 times stock power for that matter lol. All depends how much you're willing to invest, obviously an uncharted path will be more costly and time-consuming, which is where the 8v HDis are at.
I've picked up good gt20s for sub £40 in the past, it's a major punt on quality at that price though. Can pick up refurbs for 250-300. The torque will be too much for other components to handle if you have it spooling up any earlier than they do as standard, is boost at 1900rpm not soon enough..? For something with a similar boost threshold and higher flow you'll need a vnt, you can get older gt2256v refurbs for a little over £200.
As Toseland has pointed out, 16v is the way to go; heads flow a hell of a lot better and then there are injector choices galore.
