Description
The Van Der Lee Turbo Systems upgrade turbochargers for BMW S58 engines have an upgraded compressor and turbine wheel, along with ported shroud, an increased thrust capacity bearing system and improved oil sealing capacity by a motorsport type double piston ring design.
Developed as a drop-in replacement to the original turbochargers, these turbochargers will enable a reliable power output of 800+bhp (with supporting vehicle modifications), with an unrivalled transient response and time to torque performance through application of the latest compressor and turbine aerodynamic design for increased flow and efficiency, in a small package.
These turbochargers are tested and validated on a BMW M4 GT3 with a 120-hour consecutive track test and 120-hour consecutive dyno test to guarantee its reliability.
This set comes standard with choice of inlet pipes for original BMW pipe connections, Eventuri pipe connections or motorsport hose style connections.
