HKS GT7095 BB T4 A/R 0.85

If you're looking to significantly boost the power output of your performance vehicle, a well-built turbocharger is key. The HKS GT7095 BB is a serious piece of hardware designed for those who want to push their engine's capabilities further. This turbo features a T4 turbine inlet flange and a 0.85 A/R housing, which is a common setup for achieving a good balance between quick spool and high-end power on many performance applications.

What sets this turbo apart is its ball bearing center housing. Unlike traditional journal bearing turbos, the ball bearing design uses high-precision ball bearings to support the shaft. This setup offers a notable improvement in spool response, meaning the turbo starts generating boost sooner in the RPM range. It also contributes to increased durability and can handle higher shaft speeds more effectively. The 0.85 A/R (Area/Radius) ratio on the turbine housing is carefully selected to match the flow characteristics of the GT7095 compressor wheel, helping to optimize exhaust gas velocity for efficient turbine operation and improved overall performance.

This turbocharger is a substantial upgrade and is intended for custom builds where precise tuning and supporting modifications will be implemented. It's important to note that this turbo is not CARB approved and cannot be shipped to California. Proper installation will require careful consideration of oil and coolant lines, exhaust manifold fitment, and a comprehensive engine management system re-tune to take full advantage of its capabilities.
