Turbosmart TS-2-6466B-D4100E 6466 T4 Divided 1.00AR Water-Oil Ext. WG 825-955HP

Vehicle Fitment

• Universal - not vehicle-specific; designed for custom and purpose-built turbocharged applications requiring a 64mm compressor / 66mm turbine platform with a T4 Divided inlet flange and V-Band outlet connection

Fitment Notes

• External wastegate required - no internal wastegate actuator is included
• Water cooling lines required in addition to oil feed and drain; not compatible with oil-only cooling configurations
• Turbine inlet uses a T4 Divided flange - exhaust manifold must feature a matching T4 Divided flange outlet for proper fitment
• Turbine outlet is V-Band (3.00") - downpipe must be designed or adapted accordingly
• Also available in TS-1 oil-cooled configuration (TS-1-6466B-D4100E) and alternative T4 Divided A/R option (0.84AR)

Features

• T4 Divided turbine inlet housing preserves exhaust pulse separation for improved low-to-mid RPM spool response
• Water and oil cooled center section for sustained thermal control and extended bearing service life under high-load conditions
• Proprietary dual ceramic bearing system with ultra-low rotating mass for fast transient response and sharp throttle feel
• 7+7 blade 2618 aluminum splitter compressor wheel engineered for high aerodynamic efficiency across the power band
• 713C Inconel turbine wheel built to withstand extreme exhaust gas temperatures in sustained high-output use
• Lightweight 310S stainless steel investment cast turbine housing reduces overall turbo assembly weight
• CFD-optimized compressor and turbine housing geometry for peak flow efficiency at the 1.00 A/R
• VSR (Vibration Sorted and Refined) speed balanced rotating assembly for smooth, reliable operation at high shaft speeds

Product Description

The Turbosmart TS-2-6466B-D4100E is a water and oil cooled turbocharger built around a 64mm compressor inducer and 66mm Inconel turbine wheel, rated for 825-955 HP. The T4 Divided turbine housing is the defining feature of this variant - by maintaining separation between exhaust pulse streams from the manifold, it preserves scavenging energy that an open-scroll housing dissipates, resulting in quicker spool and stronger mid-range torque delivery. The 1.00 A/R rating positions this unit as a balanced choice, offering a wider usable powerband than tighter housings without sacrificing the top-end flow of a larger A/R option.

The TS-2 water-cooled center section complements the oil circuit by circulating coolant through the bearing housing, reducing heat soak during hot shutdowns and protecting the bearing assembly during extended idle periods - a key reliability advantage in high-output builds. The dual ceramic bearing system and VSR-balanced rotating assembly ensure consistent, smooth operation from spool through peak power. All installation hardware including the turbine outlet weld flange, V-Band clamp, gaskets, and oil and water fittings are included. An external wastegate is required and must be sourced separately to complete the system.
