Really, are you sure it's not a TD05-20G or possibly a T518z? I wonder how it compares to the Greddy T518z BTW? Also, I believe the GT2871r you guys are talking about is the same as the HKS GT-RS turbine, and it seems that, at least in Japan, the Greddy T518z is more popular than the HKS GT-RS. They also seem to be making higher hp figures but I'm not sure.
