Custom High-Performance Holden/Buick V6s

We specialise in building high-performance Holden/Buick V6 engines, customised to the specific needs of your vehicle.

As a well respected engine builder once told us "If you have $10 to spend, you will get $10 worth of HP." This has become central to our philosophy in engineering high-performance engines, whereby no shortcuts are taken in workflow or quality.

We pride ourselves on our attention to detail externally and pay meticulous attention to our engine build tolerances, procedures and quality.

Most engine modifications are done in-house. We also manufacture custom parts, inlet manifolds, sump and rocker covers as required for specific applications.

Engine building is our passion, and we still run and develop these engines in our own vehicles, both blown and naturally aspirated.
