No, that is a straight T3.
Note that, while the basic center 'frame' dimensions of this are indeed bigger than those of, say, a T25, this does not necessarily mean it supports more airflow. 'T2', 'T28', T3', 'T4' are no more than generic designations for turbocharger 'families'. Within each of them, there is a great variety of 'trim levels' for turbine and compressor wheels/housings available. The T3 on a B202 Saab engine, for instance, couples a .48 A/R turbine section (relatively common) to a 'trim 45' compressor - which at a practical level means it won't realistically support more than about 240 hp before seriously running out of compressor efficiency.
