When you upgrade to a hybrid version of the IS38 turbo, several key modifications help take performance to the next level:
1. Larger Compressor and Turbine Wheels
In the case of a hybrid IS38 turbo, one of the most common upgrades is installing larger compressor and turbine wheels. This allows for greater airflow, resulting in higher boost pressure and significantly more power, especially in the upper RPM range. You’ll see gains not only in horsepower but also in torque, providing a more thrilling driving experience.
2. Upgraded Bearings for Faster Spool Time
The standard IS38 is known for its relatively quick spool time, but hybrid upgrades often include advanced ball-bearing systems that reduce friction, allowing the turbo to spool even faster. This improvement means more immediate throttle response and quicker access to the turbo’s full power potential, giving you a competitive edge in both daily driving and at the track.
3. Modified Housings for Better Flow
When converting an IS38 to a hybrid, the compressor and turbine housings are typically re-machined or modified to accommodate the larger wheels and to optimize airflow. This step is crucial in maximizing the turbo’s efficiency, ensuring it can handle the higher boost levels without restrictions.
4. Built to Handle Extreme Conditions
With increased power and boost pressure comes the need for greater durability. Hybrid IS38 turbos are meticulously balanced and reinforced to handle the higher stresses associated with high-performance driving. Whether you’re pushing your Euro car on the track or enjoying spirited drives on the street, you can count on the upgraded turbo to hold up under pressure.
5. Power Across the RPM Range
The beauty of a hybrid IS38 turbo is that it delivers enhanced power across the entire RPM range. You’ll experience strong low-end torque and explosive top-end power, making it an ideal upgrade for drivers who want the best of both worlds—strong daily performance and the ability to dominate on the track.
