What does the 0.82 A/R on the turbine housing mean?

The A/R (Area to Radius) ratio of the turbine housing indicates its flow capacity. A higher A/R like 0.82 generally means the housing can flow more exhaust gas, which can help the turbocharger make more power at higher RPMs but might slightly increase spool time compared to a smaller A/R.

What kind of applications is this turbocharger best suited for?

This turbocharger is a versatile small-frame unit suitable for custom performance builds. Its T3/T4E design with a 60 trim compressor and 0.82 A/R turbine housing makes it a popular choice for increasing horsepower and torque on a variety of engines, typically in performance street or track applications.

Does this turbocharger come with oil and coolant lines?

This product listing is for the turbocharger unit itself. Oil and coolant lines, along with exhaust manifold, intake plumbing, and engine management tuning, are typically required for installation and are sold separately.

Product Details

Garrett is a well-known name in forced induction, often the go-to for reliable turbochargers that perform. This TA3405 turbocharger, part number 466159-5008S, is a small-frame unit built around the popular T3/T4E hybrid design. It features a 60 trim compressor wheel and an 0.82 A/R turbine housing, making it a solid choice for builds looking to increase horsepower and torque beyond what naturally aspirated engines can produce.

The T3/T4E designation means it combines the robust T3 turbine housing flange with a larger T4-style compressor cover and wheel. This setup offers a good balance between spool-up speed and top-end airflow, suitable for a wide range of performance applications. The 60 trim compressor wheel is a versatile size, capable of supporting significant airflow without being excessively laggy on many common engine displacements. The 0.82 A/R turbine housing provides a good flow path for exhaust gases, helping the turbocharger reach its potential without excessive backpressure.

This turbocharger is designed for custom applications where you're building a unique forced induction system. It's important to note that this unit is not CARB approved and cannot be shipped to California. Proper installation will require custom exhaust manifold fabrication, intake plumbing, oil and coolant lines, and an engine management system to tune for the increased airflow and boost pressure. Consult with your engine builder or a performance specialist to ensure this turbocharger is the right fit for your specific engine and power goals.
