    We ordered custom turbo impellers for our performance turbocharger kits. 5-axis CNC work is outstanding, every blade profile matches the 3D model. Raw aluminum finish gives us flexibility for our own surface treatment. Tolerances are tight, no rework required. Trustworthy precision parts supplier.
