Built for the Holden Commodore VL RB30ET engine, this water line kit is made to fit Garrett GT37R, GT40R, GT42R, and GT45R turbos in top mount configurations. Factory water pipes do not suit large-frame turbo setups—this kit replaces them with 6AN braided stainless steel lines and includes all fittings required for both the engine block and turbo coolant ports. This is a complete, bolt-on solution for high-heat, high-boost builds.No modification or adapter hunting necessary—all fittings are included. Custom hose lengths are available.
