The STS D21T is nothing more then a factory modified D21B with a turbo plug. When I get a modified STS I am getting the D21B it is cheaper and I do not have to run the high dollar plug.
also the .21b has a cast flat top piston, the .21T has a domed/dished billet piston... the .21T also has quite a bit more pinch from factory..
