BMW turbo V8 tuning value - BMS JB4 shows massive torque gains on 2016 F10 550i N63TU with 621 lb-ft at the wheels
The N63 and N63TU (technical update) twin turbo 4.4 liter V8's offer incredible tuning value. Although the engines are twin turbocharged and share the 4.4 liters of displacement (and some of the engine internals
) with the S63TU out of the F10 M5 the N63 manifold and turbo setup differs
That means the N63 is not quite as capable as the S63 with bolt on tuning but it still gets great aftermarket gains and is a much better value. Just look at the price of an F10 M5 and a used 550i.
One can buy a 550i, add a JB4, and have M5 performance at a fraction of the cost:
The N63 and N63TU are simply a great BMW turbo tuning value and have yet to reach their potential in the aftermarket.
