Walton Motorsport B58 Big Turbo Kit for F2X and F3X platforms including M140i, M240i, 340i and 440i.

BMW built the B58 engine to take boost but forgot to fit proper turbos. Walton’s B58 manifold allows the fitment of Garrett’s G35 series, and in particular the most popular G35-1050 model. They chose to utilize the G-Series as they produce huge power in a tiny package. These turbos are motorsport turbos and cope much better with heat and power than hybrid versions of the OEM turbo, while also offering far more efficiency. Other B58 exhaust manifolds exist, but what sets the Walton Motorsport version apart from the competition is the precision construction methods.

  • Carefully selected 304 stainless steel tube. Working to eliminate the risk of material failure
  • Fully purge-welded. Subsequently improving gas flow leading to increases in power and lowered response times
  • Ported merge collector, welded internally and externally. This results in high strength, durability and turbo lifespan
  • Fully-smoothed head ports designed to optimize gas flow, resulting in an increase of power and lowered response times
  • Optimized for use with  Turbosmart Gen-V Power Gate 60 Wastegates
  • Lifetime Warranty against manufacturing faults and defects

We assemble and sell these as full kits, ready to bolt-on. Includes:

  • Walton Motorsport 304 stainless steel B58 Big Turbo Manifold
  • Garrett G-Series G35-1050 Supercore Turbo, modified for kit use with 1.01 A/R V-band turbine housing
