I have spent a lot of time looking at this from different BMW technical articles and part diagrams on RealOEM.
From what we can see, the Supra uses the BMW B58B30M1. This the same 3.0L inline six, however, it has an integrated "headifold" meaning there is not a seperate exhaust manifold. The turbo essentially bolts directly to the head. The U.S. market Z4 uses the BMW B58B30O1 which has a normal manifold.
The headifold is used in EU markets for quicker warm-up times and increased catalytic converter efficiency when starting and cruising under operating temperatures.
There is no indication that the U.S. Supra will have the filter, however, the engine still produces the same amount of power as other markets. We cannot currently say whether or not the Supra will make more or less power than the U.S. market Z4, however, we can say that the hardware changes mean that there are likely differences in their power-making abilities.
