🔥 Flex F55 Boost X High-Mount Turbo Kit – Hilux N70 1KD 🔥

 

This is where your 1KD goes from tough to untouchable. The Flex F55 Boost X Turbo Kit is for Hilux N70 owners chasing serious street and dyno power – think 300+ RWHP potential with headroom to run up to 45 PSI.

💡 Overview
Every hit of the throttle brings faster spool and stronger pull through the mid–high RPMs. The new Ultra S-Curve turbine clears exhaust flow for more usable power and less stress on the turbo.
🚀 What Makes It Different?
  • 12% larger A/R compressor cover – higher flow & top-end power
  • Enlarged outlet – reduces blade RPM, adds longevity
  • Boost-ready to 45 PSI – headroom for serious builds
  • High-mount stainless manifold & dump pipe – durability & clearance
  • Engineered for big fuel, big air, custom tunes
