If you're chasing more response, better efficiency, and a turbo you can rely on — this GEN1 High Flow Turbo from Turbo Pros is built to deliver. It's a direct bolt-on upgrade for the 2.5L 4D56 engine, no tuning or mods needed.

You’ll get sharper boost response, improved airflow, and reduced lag, all while maintaining everyday reliability. Ideal for tired factory turbos or performance-focused replacements.

Why we rate it:

  • 15% more airflow with less lag
  • Improved fuel efficiency and throttle response
  • Bolt-on upgrade — no tuning or modifications required
  • Aluminium billet compressor wheel for high-temp performance
  • Includes turbo, actuator, gasket kit, high tensile stud kit, and pre-lube

Fits:

  • Mitsubishi Triton MN
  • Mitsubishi Challenger (4D56 2.5L diesel only)
  • Fuel type: Diesel
  • Cooling: Oil & Water
  • OEM Part No: 1515A029
  • Turbo Pros Model: RHF4H-VT10
  • Compatible with Part Nos: VA420088 / VB420088 / VC420088 / VD420088 / VE420088 / VF420088 / VT10

Choose your option:

  • Without Oil Feed Pipe – for replacements where your current pipe is in top condition
  • With Genuine Oil Feed Pipe – recommended for major turbo swaps or when your current pipe is worn or restricted

Why the oil feed pipe matters:
A clean oil feed is critical to keeping your new turbo alive. Blocked or worn pipes can starve it of oil, causing early failure. We strongly recommend the pipe option if you're unsure.
