turbo sizing for 1.9td

[optiks]

hey guys im looking to get my ex-car back on the road for my buddy okan who picked it up.

the car is a 1.9td with the following mods
 
some pump tweaks
1.6td boost pin
1.6td garett turbo
2.5" downpipe
3" exhuast
fmic with 2.5 piping

im looking for the right sized turbo that will bolt on a t3 flange sine we will be running a t3 8 v manifold

i have found this turbo and am wondering how similar it is in size to the stock 1.6td unit  http://forums.vwvortex.com/zerothread?id=3613936
