That's just a standard twin-turbo setup. V-engine, put one turbo per cylinder bank. Neither turbo feeds into the other.

A VERY basic breakdown:

Twin-turbo: two identical turbos which do not interact with each other.

Sequential turbos: two different sized turbos which also do not do much to interact with each other, but have different powerbands and therefore help the car to have a wider power band.

Compound turbos: two different sized turbos which have their hot sides integrated, AND their cold sides integrated. The purpose is similar to sequential turbos. It does a better job, but is more complicated to setup and tune.

Keep at 'er, Mike smile
