Description

The HKS SPECIAL SETUP KIT provides a sophisticated modular foundation for the ultimate GT5565_BB turbo system. It offers the complete supporting platform without the actual turbo units themselves. This strategic approach allows for maximum flexibility. It enables customers to either acquire the turbos separately or potentially reuse existing high-performance units.

By encompassing the symmetrical layout architecture, heat-resistant cast steel construction, and comprehensive integration components, this kit establishes a competition-grade infrastructure. It is capable of supporting 1,000+ horsepower while accommodating different turbo acquisition strategies.

Product Highlights

🧩 Modular System Architecture for Ultimate Flexibility
Designed as the complete turbo system infrastructure, excluding only the actual turbo units, this kit provides unprecedented flexibility for serious builders. Consequently, customers can either purchase the recommended GT5565_BB turbos separately or potentially source them through different channels. They can even contemplate using alternative high-performance units. This is possible only if those units maintain flange compatibility.

🔥 Complete Symmetrical Layout with Premium Materials
Inheriting the proven symmetrical layout philosophy from HKS’s flagship turbo systems, this kit includes all the critical components that define the installation. These are heat-resistant cast steel exhaust manifolds, GTII wastegates, precision-engineered piping, and necessary mounting hardware. Therefore, it ensures optimal exhaust gas distribution and boost balance. It also provides exceptional durability in extreme thermal environments.

🔧 Comprehensive Integration Without the Core Turbos
This setup kit thoughtfully includes virtually every component required for a complete installation. It excludes the turbos themselves. It features exhaust manifolds and wastegates with specialized engine mounts and competition air filters. As a result, it eliminates the guesswork and part sourcing. This is normally associated with building a custom turbo system from individual components.

🔄 Strategic Separation for Customer Flexibility
By decoupling the turbo units from the complete system package, HKS acknowledges that some customers may have specific preferences. These preferences might include sourcing considerations or timing constraints regarding the turbo cores. This modular approach respects customer choice. It ensures that the supporting infrastructure meets the same exacting standards as complete turnkey systems.

Performance & Construction Philosophy

Goal: To provide a complete, competition-grade turbo system platform that offers maximum flexibility in turbo unit selection while ensuring all supporting components meet HKS’s exacting standards for symmetry, durability, and integration.

Focus: Modular system architecture, symmetrical exhaust and intake layout, heat management for sustained competition use, and strategic component separation that respects different customer acquisition preferences and build strategies.

Installation & System Requirements

🔧 Complete Engine Removal Mandatory
As with all HKS full turbine systems, installation requires complete engine removal and professional modification of stock components including water pipes and turbo heat insulation.

⚠️ Essential Companion Purchases:

• Turbo Units: SYMMETERY TURBINE GT5565_BB 3BOLT A/R0.73 (14001-AK077)—one forward and one reverse rotation turbine required

• Intake System: TURBINE SUCTION KIT (14021-AN001) for complete optimized intake

• Potential Adapter: φ80-φ70 airflow adapters if using with Racing Suction Kit (70020-AN107)

🎯 Competition-Only Classification with Critical Restrictions:

• Legality: Removal of all catalytic converters makes this system illegal for public road use

• Warranty: No dealer warranty coverage due to extreme performance nature

• Filter Usage: Included single-layer gray filter intended exclusively for competition environments

Strategic Advantages & Application Rationale

🛠️ Flexible Acquisition Strategy
This modular approach allows customers to potentially stagger their investment, source turbos through preferred channels, or even consider different turbo specifications while maintaining the proven HKS infrastructure.

🔩 Proven Infrastructure with Component Choice
By providing the complete supporting system, HKS ensures optimal installation geometry, thermal management, and reliability. It allows informed customers to exercise choice regarding the actual turbo units. The turbo units are the most significant and sometimes most subjective component selection.

🏁 Competition-Ready Platform from Inception
Every component in this kit is engineered for maximum durability in sustained high-load environments. From the heat-resistant cast steel manifolds to the specialized engine mount, it accommodates different turbo positioning. It also reduces vibration transfer.

🔄 Evolutionary Compatibility with HKS Ecosystem
This setup maintains compatibility with HKS’s complete performance ecosystem. It includes the dedicated TURBINE SUCTION KIT, GT1000SPEC intercooler, and comprehensive supporting modifications for 1,000+ horsepower applications.
