There are rebuild kits for the turbo's on the VT's.
They make turbo repair kits for the Garretts GT1749V,VNT15, GT15, GT-18, and GT-20-22 which should fit your particular turbo. You can do a search on EBay for the results.
Instructions do come with them and I did buy one from ebay for about $27. I've not rebuilt one yet but when I finally source a turbo motor for my build I did plan on rebuilding the stocker and putting it to use until I get a stuffed turbo or something a bit more potent.
Hope this helps and good luck.

i haven't done any research personally but the stock turbo is a borg warner i'm not sure if the garrett stuff would fit.
