Product Highlights

💰 Accessible High-Performance with Strategic Engineering
Designed specifically to achieve 800 horsepower specifications at a reasonable cost, this kit demonstrates HKS’s commitment to delivering substantial performance gains across different budget levels. By focusing on efficient layout optimization, along with selective component enhancement, the kit provides an intelligent balance between capability and affordability.

⚖️ Symmetrical Layout for Optimized Packaging and Balance
The adoption of a symmetrical turbo layout ensures equal exhaust gas distribution and consistent boost delivery to both cylinder banks. This configuration not only improves throttle response but also simplifies installation and maintenance. This is compared to more complex asymmetrical designs.

🚀 Lightweight Compressor Technology for Enhanced Response
Utilizing a strategically sized 65.0mm compressor wheel paired with a 56.0mm turbine wheel creates an optimal balance. This balance is between airflow capacity and rotational inertia. Consequently, it delivers noticeably improved low and mid-range response compared to larger turbo systems. While still supporting significant power targets.

🔥 Heat-Resistant Cast Steel Construction for Reliability
Featuring durable heat-resistant cast steel exhaust manifolds, this system withstands the elevated temperatures of sustained high-performance operation. Additionally, twin GTII wastegates provide precise and stable boost control, ensuring consistent power delivery across various driving conditions.

Performance Philosophy

Goal: To provide a strategically balanced turbo solution that delivers substantial power gains (800PS) while maintaining responsive driving characteristics and accessible pricing—creating an ideal stepping stone between stock-modified and extreme competition systems.

Focus: Intelligent component sizing for optimal response, symmetrical layout for consistent delivery, and system integration that supports progressive vehicle development rather than requiring complete platform overhaul.

Installation & Application Strategy

🔧 Competition-Only Classification with Professional Installation
As with all HKS full turbine systems, professional installation is essential due to the comprehensive nature of the upgrade. The removal of primary catalysts classifies this as competition-only, requiring appropriate supporting modifications for road legality where applicable.

🎯 Target User Profile:

• Primary Candidates: Owners seeking significant power beyond stock-modified turbos but hesitant to immediately pursue extensive internal engine work

• Progressive Builders: Those planning a stepped approach to performance, starting with turbo upgrades before advancing to more comprehensive engine modifications

• Responsiveness Seekers: Drivers prioritizing throttle response and mid-range torque alongside peak power figures

⚙️ Supporting Modifications Recommended:

• Engine Internals: HKS pistons and connecting rods to reliably support 800PS targets

• Fuel and Management: Appropriate fueling upgrades and engine management calibration

• Cooling Systems: Enhanced intercooling to manage increased thermal loads

Performance Advantages & Rationale

📈 Strategic Turbo Sizing for Balanced Performance
The GTIII-800’s 65.0mm/56.0mm wheel configuration represents a calculated compromise. It stands between the stock 56.0mm/53.0mm dimensions and the larger GT800’s 74.0mm/60.0mm setup. This creates a “Goldilocks” sizing that delivers substantially more airflow than stock. It maintains better response than larger alternatives.

💨 Improved Low/Mid-Range Performance Over Predecessor
Despite its substantial airflow capability, the reduced rotational mass compared to the previous GT800 model improves low and mid-speed response. It results in torque delivery that equals or exceeds stock levels at lower boost pressures (120kPa). This creates a more flexible and responsive driving experience.

🔄 Logical Upgrade Pathway for Progressive Builds
The availability of a dedicated GT800 to GTIII-800 upgrade kit demonstrates HKS’s commitment to supporting customer progression. This allows owners to evolve their systems alongside their performance goals. It does not require a complete replacement of existing investments.
