How it’s built
The factory turbochargers are disassembled and thoroughly inspected. The compressor cover and centre cartridge are precisely machined to accept a new 5‑axis CNC‑machined impeller wheel. Externally, the housings remain unchanged to maintain a discreet, factory look. Each unit is reassembled with new seals and high‑RPM balanced for smooth operation and OEM‑level service life. This is a premium, no‑compromise performance turbo upgrade for the S63TU that keeps the stock fit and finish.
