Wastegate vs. Non-Wastegate Turbocharger – Which One to Choose?
A key decision when purchasing your Cummins ISX Turbo Conversion Kit is choosing between a wastegate and non-wastegate turbocharger:
- Wastegate Turbocharger – Uses a bypass valve to regulate boost pressure, preventing over-boosting. Ideal for those needing more precise control over turbo pressure.
- Non-Wastegate Turbocharger – A simpler design that relies on turbo sizing for boost control. Best suited for applications where over-boosting risks are minimal.
Why Choose Our Cummins ISX Turbo Conversion Kit?
- Improved Reliability – Eliminates common issues with the factory VGT turbo.
- Increased Performance – More efficient power delivery and engine response.
- Enhanced Fuel Economy – Reduced exhaust restrictions improve combustion efficiency.
- Longer Turbo Life – A simplified turbo system means fewer moving parts and less maintenance.
- Models we cover – CM870, CM871, CM2250, CM2350 – we cover them all
Important Notes:
- This Turbo Conversion Kit for Cummins ISX requires EGR Delete and ECM Reprogramming for proper function. ECM tuning is not included in the kit.
- Professional installation is recommended for optimal performance.
