Performance Gains:
- Horsepower Increase: Up to +459 HP

Next-Level Turbocharger Design:
The M157 W.4 Turbochargers utilize twin ball-bearing technology paired with CNC-machined billet aluminum compressor wheels, delivering unparalleled airflow for substantial power increases. These advanced turbochargers completely replace the factory units and include redesigned Weistec Turbo-Folds to maximize exhaust gas flow, ensuring optimal turbine efficiency.
Enhanced Intake and Exhaust System:
To feed these high-performance turbos, the upgrade includes new Weistec M157 Turbo Intake Tubes, with optional Weistec Carbon Airboxes for further intake efficiency.

Engineered for Power and Reliability:
The W.4 Turbo Upgrade enables the M157 engine to produce 1000+ crank horsepower with supporting upgrades, even on 91-octane pump gas. Operating at only 20 psi, the turbos achieve massive power gains while maintaining drivetrain reliability. With optional Weistec ECU tuning, boost pressure is strategically controlled to limit torque to under 800 lb-ft at the wheels, reducing stress on the connecting rods and drivetrain components. For fully built M157 engines, the W.4 system can deliver 1400+ crank horsepower with supporting modifications.
