Unlock serious gains with the CRC 44mm VNT Turbo Upgrade — engineered for the Mitsubishi Triton 4N15 2.4L engine. Designed for those chasing torque, power, and reliability, this premium turbo delivers up to 30psi boost and 230HP with direct bolt-on fitment.
This turbo suits the following vehicles:
Important: Please specify your model & year when ordering, or check if you have the sensor plug on your turbo. MR models (late 2018+) have sensor plug, MQ models (pre-2018) do not.
Power output capabilities:
⚠️ Tuning Recommendation: While no tuning is required for basic operation, +30% injectors and ECU remap are strongly recommended to safely maximise gains and protect your engine.
Note: Compressor wheel design may vary slightly from product photos. All units meet CRC performance specifications.
Installation difficulty: Moderate — turbo replacement requires mechanical knowledge
Recommended supporting modifications for maximum performance:
Q: Is this turbo a direct bolt-on?
A: Yes — this 44mm CRC Turbo Upgrade bolts directly onto 4N15 2.4L engines with no modifications required to the engine.
Q: Do I need tuning after install?
A: Generally not required for basic use, but an ECU remap and +30% injectors are strongly recommended to unlock full performance safely and avoid over-fueling or excessive EGTs.
Q: What power gains can I expect?
A: With supporting mods (injectors, tune, exhaust, intercooler), the turbo supports up to ~230HP and 30psi boost while maintaining factory drivability.
Q: Which vehicles does it suit?
A: This turbo suits Mitsubishi Triton MQ (2015–2018), MR (2018–2024), and Pajero Sport QE/QF (2015–2025) with the 4N15 2.4L engine.
Q: What's the difference between MQ and MR turbos?
A: MR turbos (part 1515A322) have a sensor plug on the actuator. MQ turbos (part 1515A295) do not. Functionality is the same, just different plug configuration.
Q: Is everything included for install?
A: Yes — the turbo comes with all required gaskets for a straightforward installation. You'll need basic tools and mechanical knowledge.
Q: Will this void my warranty?
A: Performance modifications can affect manufacturer warranty. Check with your dealer before modifying a vehicle under warranty.
Q: Can I run this turbo without injectors or tune?
A: The turbo will bolt on and run, but you won't achieve full performance gains without upgraded injectors and tuning. Running high boost without proper fueling can cause EGT issues.
Q: How does this compare to factory boost?
A: Factory 4N15 runs approximately 17psi. This turbo can safely deliver up to 30psi with proper supporting mods, representing a significant performance increase.
