This still seems to be blown out of proportion. It’s not a massive “upgrade”, it’s just a big change, the two are not the same thing.You've missed a lot. The 2021 Supra uses the BMW M340i, which contains a host of design upgrades. Chief among them are the six (vs. 2) exhaust port heads and matching manifold. The engine also uses a higher capacity fuel system, a much more effective "split" cooling system, a lower compression ratio that permits higher boost levels...
So extensive are the changes that referring to the engines as "two different engines" isn't much of a stretch.

Your claim about an upgraded fuel system, I’ve not seen any Toyota source that makes that claim anywhere. Maybe for the m340i they’re getting a fuel pump upgrade to match the supras, but the Supra now has a much larger capacity fuel pump then the m340i
