• 🌀 7-Blade Compressor Wheel – rapid spool & reduced lag
• 📈 12% Larger AR Housing – increased airflow & mid-range torque
• ⚙️ High-Performance Bearings – sustained reliability under high boost
• 🔩 44mm / D-MAX Style Rear Flange – broad manifold compatibility
• 🔥 300+ RWHP Capable – with supporting mods and tuning
• 💪 45 PSI Boost Rating – extreme performance headroom

• Toyota Hilux N70 1KD-FTV (2005–2015) – requires aftermarket 44mm/F55 high-mount manifold
• Holden Rodeo RA7 4JJ1 (2007–2008)
• Holden Colorado RC 4JJ1 (2008–2012) – minor manifold mods required
• Isuzu D-MAX 4JJ1 (2008–2016, non-DPF) – minor manifold mods required

⚠️ IMPORTANT: Later 4JJ1-TCX D-MAX (2016–2020) requires custom manifold, dump pipe, DPF & EGR delete and other modifications.

• Flex F55 Boost X Turbocharger
• Wastegate Actuator + Relocatable Bracket
• Oil Feed & Drain Hose Kit (D-MAX low mount)
• Turbo & Engine Block Oil Fittings
• Dump Pipe Studs & Copper-Coated Nuts

To achieve 300+ RWHP and safely run 45 PSI boost:

Required:

• ✔ High-mount manifold (44mm/F55 type) or modified factory manifold
• ✔ Custom dump pipe
• ✔ DPF & EGR delete (where applicable)
• ✔ Custom ECU remap – mandatory for safe operation

Highly Recommended:

• ✔ Fuel upgrades: +60% / +100% injectors
• ✔ Larger intercooler – handle 45 PSI boost
• ✔ Upgraded fuel pump – strongly recommended
• ✔ High-flow exhaust – 3" minimum
• ✔ Boost & EGT monitoring – essential for safety

• Manifold drilling, tapping or port-matching may be required on some 4JJ1 models
• Later D-MAX 4JJ1-TCX requires custom manifold, dump pipe and emissions deletes
• 1KD applications require aftermarket high-mount manifold
• Professional installation strongly recommended
• Ensure clean oil feed/return before installation

Foundation requirements for 300+ RWHP:

Fuel System:

• +60% or +100% injectors
• Upgraded fuel pump (optional but recommended)
• Rail blank or upgraded relief valve

Air System:

• Flex F55 Boost X turbo (45 PSI capable)
• Large front-mount intercooler
• High-flow intake system
• 3" exhaust system minimum

Tuning & Monitoring:

• Professional ECU remap mandatory
• Boost gauge (accurate to 50 PSI)
• EGT gauge for safety
• Wideband O2 sensor (tuning phase)

Drivetrain Considerations:

• Clutch upgrade (manual transmissions)
• Transmission service and inspection

Q: Is this a direct bolt-on turbo?

A: Not entirely. 1KD requires aftermarket high-mount manifold. 4JJ1 applications may need minor manifold modifications. Custom dump pipe required for all applications.

Q: What makes the Boost X different from standard F55?

A: The Boost X features a 7-blade compressor wheel (vs 6-blade), 12% larger AR housing, upgraded bearing system, and is rated for 45 PSI boost and 300+ RWHP builds.

Q: Do I need a tune?

A: Yes – ECU tuning is mandatory. The F55 Boost X's extreme boost capability requires professional calibration for safe fueling, timing, and EGT management.

Q: What power can I realistically expect?

A: With proper supporting modifications (injectors, fuel pump, intercooler, exhaust) and professional tuning, 300+ RWHP is achievable. Results vary based on build quality and tuning.

Q: Can I run this on my daily driver?

A: When properly tuned and with appropriate supporting mods, yes. However, this is an extreme performance turbo designed for serious builds. Consider reliability vs performance goals.

Q: What boost should I run?

A: The turbo is capable of 45 PSI, but safe boost levels depend on your complete setup. Your tuner will set appropriate targets based on injectors, fuel system, intercooler, and usage. Typical builds run 35-40 PSI.

Q: Will this fit later model D-MAX (2016-2020)?

A: Yes, but requires custom manifold, dump pipe, DPF delete, and EGR delete. Not a simple bolt-on for these models.

Q: What's included in the kit?

A: Complete kit includes turbo, wastegate actuator with relocatable bracket, oil feed/drain hose kit, oil fittings, and dump pipe studs/nuts.
