Stage 2 High-Flow Twin Turbochargers for S55 engines

Unlock huge performance from your F80 M3, F82 F83 M4 and F87 M2 Competition with these Stage 2 HF high-flow twin turbochargers. Designed specifically for the S55 powerplant, these uprated units deliver serious gains with OEM-style fitment and everyday drivability. Developed on an in-house M4 since 2014 and proven on the dyno at 632 whp early on, continual refinement has seen builds exceed 700 whp with the right supporting hardware and calibration. Record-setting S55 projects worldwide rely on this upgrade for both power and reliability.

We have fitted these turbos for customers and on our own cars, and the results are outstanding. Rapid spool, strong mid-range, and relentless top-end make them a favourite for fast road, track days, and drag builds.
