I'm wondering if it's a sequential turbo setup or a traditional parellel turbo.... I'm guessing since the motor is a straight design with only one exhaust manifold, it'll be a sequential setup.

If it did turn out to be sequential turbo, I would be concerned about longterm reliability. Toyota and Mazda had sequential turbos back in the 90's and they both had issues with long-term reliabiltiy. There is too much plumbing and controls involved in making the two turbos (one smaller and one larger) play together nicely.

We shall see....
