W.3 Hybrid Turbochargers for BMW S63TU V8 4.4 litre

Turn your F-series M car into a true heavy hitter with the Weistec W.3 hybrid turbo set for the S63TU 4.4 litre V8. This plug-and-play pair is engineered to deliver massive gains while keeping factory-like drivability and a discreet OEM appearance. Expect brutal mid-range punch, rapid spool and relentless pull to the redline. Quoted output from Weistec is up to 890 HP and 850 TQ when supported by the right calibration and hardware.

At MJ Modifications we have fitted these on S63TU platforms and the feedback is consistently outstanding. Customers love the sleeper look, the instant response and the way these chargers transform the car for spirited road use and track days.

Why this upgrade stands out

• Hybrid turbos tailored for the S63TU V8 in F10 M5, F12 and F13 M6, F85 X5M and F86 X6M

Precision engineering

Each unit starts with the original housings which are disassembled and inspected. The compressor cover and centre section are CNC machined to accept a new 5-axis billet compressor wheel. The externals remain unchanged to maintain the OEM appearance. Every turbo is reassembled with fresh seals and VSR balanced to high RPM for smooth, reliable operation and long service life.
