What is included with this BorgWarner turbocharger?

This product is the BorgWarner SX S1BG T25 turbocharger assembly. It includes the core turbo unit with the specified turbine housing and compressor wheel.

What does the .46 A/R ratio mean for the turbine housing?

The .46 A/R ratio on the turbine housing indicates its size and flow characteristics. A smaller A/R like .46 generally promotes quicker turbocharger spool-up, meaning it will reach boost pressure earlier in the engine's RPM range, reducing turbo lag.

Why is this turbocharger not CARB approved?

This turbocharger is not CARB (California Air Resources Board) approved. This means it does not meet California's emissions standards for aftermarket parts, and therefore cannot be legally shipped to or installed in California.

Product Details

This BorgWarner SX S1BG turbocharger assembly includes the core turbo unit itself. It features a T25 turbine housing with a .46 A/R ratio and a 39mm inducer diameter on the compressor wheel. This setup is designed for enthusiasts looking to add or replace a turbocharger on their vehicle, aiming for improved performance through forced induction.

The SX S1BG series from BorgWarner is known for its robust construction and reliable operation. The .46 A/R turbine housing is a common choice for smaller displacement engines or applications where quick turbo spool-up is prioritized, helping to reduce lag and provide boost sooner in the RPM range. The 39mm compressor inducer diameter is sized to match this turbine housing for balanced airflow and efficient boost delivery. This turbocharger is built with durable materials to withstand the high temperatures and pressures associated with turbocharging, ensuring longevity and consistent performance.

When installing this turbocharger, it's important to ensure your engine's oiling and cooling systems are in top condition, as turbochargers rely heavily on clean oil for lubrication and cooling. Proper exhaust and intake plumbing will also be necessary to integrate this unit into your vehicle's system. Due to its design and intended use, this turbocharger is not CARB approved and cannot be shipped to California.
