These figures come from GCG's own on-dyno testing against the OEM turbocharger — not manufacturer estimates:

• Up to 265BHP / 198kW — +38% power increase vs OEM turbo
• Up to 550Nm — +70% torque increase from 320Nm (OEM) to 550Nm, tested on-dyno

⚠️ Important: To get the most out of your PowerMax, GCG recommends re-tuning your vehicle. Without tuning, overall torque and power results may vary. Maximum turbocharger shaft speed is 171,600 RPM — operation above this is at the owner's risk.

G953907-5001S suits:

• Toyota Hilux KUN16R 1KD-FTV D-4D 3.0L — 03/2005 to 09/2015
• Toyota Hilux KUN26R 1KD-FTV D-4D 3.0L — 03/2005 to 09/2015

✅ Hilux KUN26 is direct plug-and-play — no wiring harness required. The PowerMax uses a calibrated electronic actuator that matches the factory connector on the KUN16R/KUN26R straight out of the box.

❌ This is the Hilux-specific unit. For Prado KDJ120, see our separate Prado 1KD Garrett PowerMax listing — different part number, different RRP.

The GCG Garrett PowerMax is not simply a rebranded standard turbo. It's a purpose-built performance upgrade with specific improvements over both the OEM IHI unit and the base Garrett replacement:

• Improved electric actuator assembly — redesigned for increased durability. The factory IHI actuator is a known failure point on high-mileage 1KD-FTV engines
• Calibrated actuator — factory-set to ensure accurate vane positioning from day one
• Fully machined speed sensor port — allows turbo shaft speed monitoring via G-Smart Bluetooth Module (G923586-0002) or Speed Sensor Kit (G781328-0001/0002), sold separately
• Dyno-tested performance — GCG's own testing confirms 38% power increase and 70% torque increase vs OEM

💡 The OEM IHI CT16V electric actuator is a well-documented weak point — they fail, they drift out of calibration, and replacements cost hundreds. The PowerMax comes with Garrett's redesigned, improved actuator built to outlast the original.

• Re-tuning is strongly recommended to unlock the full performance potential of the PowerMax
• Without tuning, results will vary and the dyno-tested power figures may not be achieved
• Running a 3-inch exhaust without a tune can trigger a P1251 overboost fault on the factory ECU
• Turbo shaft speed monitoring recommended — G-Smart Module (G923586-0002) or Speed Sensor Kit (G781328-0001 / G781328-0002), sold separately

• Direct plug-and-play for Hilux KUN16R/KUN26R — no harness modifications required
• Always flush the oil feed line before fitting
• Prime with clean oil before first startup
• Idle for 2–3 minutes before driving to allow oil pressure to build through the new bearing
• Gaskets and oil/coolant lines are not included
• Professional installation recommended

⚠️ Always identify the root cause of your original turbo failure before fitting. Oil contamination and starvation are the leading killers of new turbochargers.
