GT1749va is the PD130 turbo
GT1749vb is the PD150 turbo
Both are interchangeable though. I just found the 150 turbo a bit more laggy tbh.
There are loads of GT1749v* though, the GM CDTi150's use one as well.
When I changed mine on the Golf (2.5 years ago) there weren't many used ones about and couldn't find one at scrap yards...ended up having to buy recon at like £300!
Did get £100 back for the dead turbo though....
