A first turbocharger includes a first turbine having at least one inlet and an outlet, and a first compressor having an inlet and an outlet. The at least one first turbine inlet is fluidly coupled with a corresponding exhaust manifold. A second turbocharger includes a second turbine having at least one inlet and an outlet, and a second compressor having an inlet and an outlet. The at least one second turbine inlet is fluidly coupled with a corresponding exhaust manifold. A valve assembly includes an inlet, a first outlet and a second outlet. The valve inlet is fluidly coupled with a corresponding first turbine inlet, the valve first outlet is fluidly coupled with the second turbine inlet, and the valve second outlet is fluidly coupled with at least one intake manifold.
