I won a GT2559V turbo off ebay a month ago which I plan to fit to my 1.9 Dturbo, currently running an Audi TT K04 turbo.
Here's some size pics
It's quite a large brute and I'm sure your all thinking it's going to be laggy but it's a variable nozzle turbo so this means it spools up super quick at low RPM's so it suited perfectly for diesels.
So far I've managed to clock the cartridge so the oil line sits upwards, drilled the manifold for the bolts and just needs thread tapping into it. I've had a plate made for the down pipe which I'm collecting tomorrow then need get the downpipe lined up and welded on there.
I'll keep updated with progress for those interested.
