SIMPSON OFF-ROAD ENGINEERING

Australian Made Turbocharging Accessories

Based in the Southern Highlands of NSW, Simpson Off-Road Engineering was founded to service a need for cost effective solutions to turbocharge the legendary naturally aspirated 1HZ Toyota engine. 1HZ engines power over one million Toyota Landcruisers and Coaster buses across the globe and are still being produced today - a reliable and capable engine that benefits greatly from turbocharging.

Our Australian made products enable owners to spend more funds on a quality turbocharger when modifying their engine, making use of existing components rather than changing them when completing a turbo installation.

Proudly Australian Made.
