UFI 1HZ Turbo Kit suitable for Toyota LandCruiser 70 80 105 Series

UFI 1HZ Turbo Kit suitable for Toyota Landcruiser 70 80 105 Series 1HZ

A reliable, high-performing turbo upgrade designed specifically for the naturally aspirated 1HZ engine. This UFI turbo kit brings the power, torque, and drivability you’d expect from a factory-turbo LandCruiser, without cutting corners.

🔥 Why Turbocharge Your 1HZ?

The 1HZ is a fantastic engine but underpowered by modern standards. The UFI 16G Turbocharger included in this kit looks and sounds great with a huge 4″ Anti-surge inlet, transforming the driving experience with increased torque, fast response, and better towing performance, while maintaining reliability.

 We’ve seen:

• A typical Power increase from ~70hp to 120–140hp at the wheels (Measured on our Mainline Dyno)
  
• Big drivability gains across the rev range
• Lower EGTs and better performance towing

The goal isn’t big dyno numbers, it’s usable power and torque where it counts.

🚗 Suitable for:

• Toyota LandCruiser models fitted with 1HZ engine
• HZJ75 / 78 / 79 Series Landcruiser
• HZJ80 Series Landcruiser
• HZJ105 Series Landcruiser

📦 What’s in the kit:

• CT26-based UFI 16G Turbocharger – direct bolt-on fitment
• Braided AN4 oil feed line with T-piece
• AN10 oil return hose with weld-on sump fitting
• Tillix Split Pulse Merge Exhaust Manifold
• Metal MLS manifold gasket + sealing rings If required with stock manifold
• Intake crossover bung with ⅛” BSPT thread
• Turbo outlet to crossover pipe
• All required fittings, fasteners, and clamps
• Optional: Turbo to intake pipe (To suit standard 1HZ airbox)
• Optional: Compete Manta exhaust system, or 3″ dump pipe for creating your own custom exhaust.

🛠️ Fitment Details:

• Uses OEM 1HD CT26 style components
• 1HD-T style front manifold bolts to factory “rear half”
• Oil feed from the passenger side oil pressure switch port
• Welding required for oil drain to sump. (Supplied fitting must be welded both inside & outside the sump due to double skin)
• No water cooling required – turbo is oil-cooled only
• Valve cover breather rerouted to pre-turbo intake pipe (not to crossover)
• Bung included to block off the factory crossover breather port
• If using an aftermarket airbox, a 4″ Intake pipe is required for the UFI Turbo

🔧 Tuning Information:

🤔 Why we used the parts we have with this kit:

• UFI (United Fuel Injection) 16G Turbocharger Designed to achieve the maximum torque and power from 1H series of engines
• CT26 turbo housing keeps factory ‘1HD-T style’ fitment, no dump pipe or intake mods needed
• Tillix split pulse merge manifold gives robust sealing and proven gas flow for turbocharging
• No water lines – less plumbing, less chance of leaks

❓ Frequently Asked Questions

Q: Do I need to weld anything?
A: Yes, the sump oil return requires welding in a supplied AN8 fitting. It must be welded both inside and outside the sump due to double-skin design.

Q: Does this include a full exhaust?
A: No. If you selected the dump pipe option, it includes a 3” dump for custom exhaust fabrication. We also offer full turbo-back systems, just reach out to us.

Q: Can I run this without an intercooler?
A: Yes, the kit works well without one, but adding an intercooler is recommended for higher boost levels or towing applications.

Q: Do I need to tune it after install?
A: Yes, a dyno tune is highly recommended. To increase the power, your fuel delivery must be increased to match airflow.
