Fitting a larger axle, such as a GTB28 or GTB25 to a GTB22 turbo, has several potential advantages:
1. **Increased Strength**: A larger axle is generally stronger, which can help prevent failure under heavy loads or high engine speeds.
2. **Better Performance**: This can improve performance by allowing the turbo to better handle higher airflows, which is especially useful for high performance applications.
3. **Reduced shaft bending**: A larger shaft reduces the likelihood of bending under high loads, improving turbo reliability and life.
4. **Improved Response**: In some cases this can improve turbo response, although this depends on the specific turbo and engine design.
5. **Higher Power Support**: A larger shaft can allow the turbo to support greater amounts of power without sustaining damage.
It is important to note that these improvements depend on the quality of the modification and compatibility with the specific turbo system and engine. Additionally, there may be drawbacks, such as the need for additional modifications to accommodate the larger axle, or a possible impact on long-term durability if the modification is not done correctly.
