CRG started out making steam pipe manifolds for mostly street car applications to suit larger turbos with external wastegates and required precise packaging to fit under the bonnet. Cast manifolds are good for factory produced engines and vehicles but have limited life and upgrade options, cheap chinese manifolds are not good for much at all, but a well designed and over engineered steam pipe manifold is a must for performance, packaging, flexibility in design and very importantly - durability.

Our manifolds have become extremely popular and sought after on performance street cars, circuit cars, drag cars, ski boats and off road vehicles.

Our manifold design and production then evolved into full car turbo system fabrication cooling systems and almost any fabrication required.

A personal interest in off roading, Fraser Island, Bribie Island, Cape York trips and 4x4s then evolved into finding design flaws and weaknesses in factory developed parts then redesigning and developing improved upgrades for cars like the Nissan Navara D23 NP300 (Frontier South America), Ford Ranger, Holden Colorado and other equivalents.

Our exploration in off roading and camping have lead us down the path of working with Australian companies that are developing and producing some of the best cooling and suspension components around. We supply and fitting CRG / PWR intercoolers, cooling components, Superior Engineering Suspension, King Springs and Lovells Suspension Specialty Products for most make and model 4x4's.
