The Holden L36 Ecotec V6 engine was a game-changer in Australian motoring, delivering a balance of performance, fuel efficiency, and reliability. Introduced in the VS Commodore Series II in 1996, the Ecotec (Emissions and Consumption Optimisation through Technology) was a significant upgrade to the earlier L27 Buick based 3.8 V6. This new engine achieved improved fuel economy, cleaner emissions, and enhanced power delivery thanks to reduced friction, lighter internals, and revised cylinder heads. The Ecotec quickly became synonymous with Holden’s success, powering Australian icons like the VT and VX Commodore.

With its reputation for reliability and a solid aftermarket following, the Ecotec remains a popular choice for enthusiasts restoring or modifying vehicles from this era. Its adaptability in performance applications, coupled with the wide availability of parts, makes it a favourite among Holden fans across Australia. T.I. Performance is proud to support Ecotec owners with high-quality components and tuning solutions tailored to this legendary engine.
