Estimated Performance Gain

The Precision Turbo IS38 Stage 1 is designed to provide substantially greater airflow capacity than a factory turbocharger while maintaining a direct-drop-in configuration.

The final power output depends heavily on ECU calibration, fuel, intercooling, exhaust flow, intake configuration, and supporting modifications.

Maximum rating: up to approximately 575 HP.

These figures represent estimated overall vehicle potential with the upgraded turbocharger and appropriate supporting hardware, rather than guaranteed horsepower gains from the turbocharger alone.

Reaching the upper end of the turbocharger’s capability may require additional upgrades such as fuel-system components, intercooling, intake, exhaust/downpipe, and a properly calibrated ECU tune.

Actual results will vary depending on fuel quality, boost pressure, ECU calibration, engine configuration, supporting hardware, ambient conditions, and tuning strategy.

Why Upgrade?

The factory turbocharger can become a limiting factor as power targets increase. The Precision Turbo IS38 Stage 1 provides increased airflow capacity while maintaining a direct-drop-in configuration designed for straightforward installation.

Its 50mm CEA compressor wheel is engineered to provide increased airflow while maintaining quick response, while the high-flow CEA turbine wheel helps improve exhaust flow and high-RPM efficiency.

Combined with the water-cooled dual ceramic ball-bearing center cartridge, this turbocharger is designed to deliver a strong balance of response, efficiency, reliability, and top-end power.

For enthusiasts looking for a substantial power increase without moving to a larger custom turbocharger setup, the Precision Turbo IS38 Stage 1 provides a high-performance upgrade in a compact package.

Turbocharger Specifications
