CCT Stage2 High-Flow Upgrade Turbo for Toyota Hilux / Prado / Surf / 4Runner 1KZ-TE 3.0L CT12B

1. My 1KZ engine is high mileage. Is it safe to upgrade to Stage 1 or Plus?
Yes, absolutely. The 1KZ is legendary for its strength. Our Stage 1 (12 PSI) and Stage 1 Plus (15 PSI) focus on improving induction efficiency. With the Reinforced HD 360° Thrust Bearing in our Plus and Stage 2 series, our turbos are over-engineered to handle increased boost while protecting your engine's longevity.

2. What is the real-world difference between Stage 1 and Stage 1 Plus for a 1KZ?
Stage 1 is a response-focused upgrade (factory size Billet wheel). Stage 1 Plus is a power and safety upgrade featuring a 2mm larger Billet wheel and an upgraded 9-blade Inconel 713C turbine. This combination pushes more air and reduces backpressure, keeping your 1KZ running cooler under heavy load.

3. Why did CCT choose a 9-blade turbine wheel for the 1KZ Plus and Stage 2 models?
The original 1KZ turbine creates significant backpressure. Our 9-blade High-Flow Inconel design allows the engine to breathe out more effectively. This lowers heat stress on your cylinder head—the most critical protective measure for any 1KZ-TE engine.

4. I tow a caravan with my 1KZ Prado. Will the Stage 2 (4mm bigger wheel) cause lag?
No. Thanks to the ultra-lightweight forged MFS Billet material, even our larger Stage 2 wheel has less inertia than the factory cast wheel. It spools up faster, delivering immediate low-end torque for pulling away with heavy loads while providing massive mid-range grunt.

5. Is a custom ECU tune or Diesel Chip required for these 1KZ upgrades?
While Stage 1 and Stage 1 Plus will run safely on factory settings, we recommend a professional fuel adjustment or chip to fully utilize the 15 PSI potential. This ensures your 1KZ has the correct fuel mixture to match the increased airflow, maximizing power and safety.

6. Is this 1KZ turbo a direct bolt-on for my Hilux, Prado, or Hiace?
Yes, 100%. All CCT 1KZ series turbos are designed as true direct bolt-on replacements. Our units match all original oil lines, coolant ports, and manifold mounting points exactly for a hassle-free installation.

7. How does this upgrade help reduce the common 1KZ "black smoke" under load?
Black smoke is a sign of incomplete combustion. By induction of a higher volume of air more efficiently via our Performance Design Billet wheels, our turbos clean up the combustion process, reducing soot buildup and black smoke while increasing power.

8. Are these high-performance units high-speed balanced in Australia?
Absolutely. Every CCT performance unit is high-speed VSR balanced and flow-calibrated in our Melbourne facility. This eliminates microscopic vibrations and ensures maximum bearing life and whisper-quiet operation.

9. Is a gasket kit included for a complete installation?
Yes, this turbo comes with a free set of gaskets as photo shows. We include the essential manifold, oil, and coolant seals required for a professional, leak-free installation on any 1KZ vehicle.

10. Does CCT offer a repair service if I experience an issue years down the road?
Yes! Aside from our 24-Month Warranty, we provide an exclusive Life-Time Cost Price Repair Service for all CCT branded turbos. We are committed to supporting the 1KZ community and keeping your vehicle powered for life.
