A Legend. Made Better.
The Landcruiser 100 Series is regarded as one of the greatest 4WDs ever produced. The 1HD-FTE inline-six diesel is known for its durability and longevity — and it still has real performance potential that factory tuning leaves untapped.
At Stealth Installs we work on 100 Series vehicles regularly, from fresh-market imports to high-kilometre Australian vehicles. We know how to get the best out of the 1HD-FTE reliably and set these vehicles up for serious Australian touring.

What We Do for Your 100 Series
Proven modifications for the 1HD-FTE platform.
ECU Remapping
The 1HD-FTE is a well-proven engine with good tuning potential. A quality remap delivers stronger torque across the rev range, improved throttle response, and better fuel economy on long trips.
Intercooler Upgrades
An upgraded intercooler reduces heat soak under sustained load — critical for touring in Australian conditions or towing heavy trailers over long distances.
Exhaust Systems
A free-flowing 3" stainless exhaust reduces backpressure on the 1HD-FTE, helping the turbo breathe more freely and supporting the remap for stronger performance.
Catch Can Systems
Blow-by management is important on the 1HD-FTE, especially on higher-kilometre vehicles. A catch can helps protect the intake from oil contamination over the long term.
Suspension Upgrades
The 100 Series is a heavy vehicle often loaded up for touring. We build correct-rate suspension setups that handle real-world loads while maintaining ride quality.
Touring & Accessory Builds
Dual battery systems, auxiliary lighting, roof rack setups, and communication gear — we build complete 100 Series touring rigs ready for remote Australian travel.
