66mm Inducer Compressor Wheel:

The 66mm inducer compressor wheel is capable of flowing massive amounts of air, supporting high horsepower levels. The large compressor wheel allows the turbo to generate significant boost pressure while maintaining efficiency. The compressor is designed to work with the 80/74mm turbine wheel for balanced performance.

T4 Turbine Inlet Flange:

The T4 flange is a universal standard used on many aftermarket turbo manifolds. The T4 flange is larger than T3 flanges, allowing for greater exhaust flow and supporting higher horsepower levels. The T4 flange makes the S300SX3 compatible with a wide range of aftermarket manifolds for diesel and gasoline applications.

A/R .88 Turbine Housing:

The A/R (Area/Radius) ratio of .88 provides a balanced combination of quick spool and strong top-end power. The .88 A/R is larger than typical .63 or .70 housings, which means it flows more exhaust and supports higher horsepower levels. However, it still provides reasonable spool characteristics for street and performance applications.

80/74mm Turbine Wheel:

The 80/74mm turbine wheel features an 80mm inducer (inlet) and 74mm exducer (outlet). This large turbine wheel flows significant exhaust volume, allowing the turbo to support high horsepower levels. The turbine wheel is precision-balanced and designed to withstand extreme exhaust gas temperatures and pressures.

Why BorgWarner?

BorgWarner is a world-leading manufacturer of turbochargers for OEM and aftermarket applications. Their turbos are known for exceptional quality, reliability, and performance. BorgWarner turbos are trusted by professional engine builders and enthusiasts worldwide for proven power and durability. Every BorgWarner turbo is manufactured to strict quality standards.

Professional Tuning Required:

CRITICAL: Professional tuning is absolutely required after turbocharger installation.
