Upgrade your 2JZ-GTE or 1JZ-GTE engine setup with the Bull Boost Billet Lower Water Neck, designed for maximum efficiency and flexibility. This water neck bolts directly to the OEM water pump, eliminating the need for a rotator adapter, simplifying installation. Its design is rotated and clocked straight down behind the alternator, providing optimal space for single turbo setups.
The Bull Boost Lower Water Neck features a versatile dual-purpose end, equipped with female -16 ORB threads, giving you the option to convert to AN hoses or stick with an OEM lower radiator hose or silicone hose kit. It works seamlessly with your OEM Toyota thermostat or any aftermarket options for the 2JZ or 1JZ engines. To ensure correct alignment, a machined mark on the back of the neck assists with proper thermostat installation.
