JapDirect 6+6 Billet Turbocharger - Toyota 1JZGTE VVTI (CT15B Upgrade)

Unlock the full potential of your 1JZ-GTE VVTI with the JapDirect 6+6 Billet Turbocharger.

A precision-engineered, budget-friendly, direct bolt-on upgrade designed to outperform the factory CT15B.

Featuring a massive jump in compressor and turbine size (OEM CT15B 48mm front wheel / 48mm rear wheel vs. JapDirect 66mm billet front wheel / 58mm billet rear wheel), this turbocharger delivers significantly more airflow and top-end power while retaining OEM fitment and reliability.

Perfect for enthusiasts looking to step beyond stock limits on a budget, without the hassle of Custom Fabrication or Aftermarket ECU.

⚠️ Important Information:

Warranty/Disclaimer: All JapDirect turbochargers are sold as-is for off-road/motorsport use only. Installation must be done by a qualified professional.

JapDirect is not responsible for any damage to the engine, car, or components.

This unit is still in the final stages of development, testing and is currently undergoing extensive road testing and analysis. Please note that this product is available to order but because testing is ongoing, final results and performance outcomes may vary. 

There may be components you will need to swap over from your original turbocharger such as studs, rubber hoses, oil feeds, lines, etc.

While the factory intake pipe will bolt up to this turbo and will operate, we do recommend having a new turbo inlet pipe made to the face of the turbo, to suit the larger compressor wheel for optimal fit and performance.

JapDirect strongly recommends checking your air-fuel ratio after installation to ensure safe operation, optimal performance, and engine reliability. If aftermarket engine management is fitted, a professional dyno tune is recommended.

Installation of this turbo may require additional supporting modifications, such as an improved intake, exhaust or fuel system. 

Any warranty claims applies only to the turbo itself. JapDirect is not responsible for any damage to the engine, vehicle, or other components. By purchasing this product, you agree to these terms.
