TracTuff PRB/ PRC Billet Water Neck w/ Swirl Tank & Overflow
A version of my PRB/ PRC swirl tank with an integrated overflow; eliminates the need to route an overflow hose to the core support or frame rail, where an overflow might usually be found. Due to the weight of this unit, mixed with heat and vibration... I do NOT recommend this product for RACE CARS.
Our billet water neck has the largest port allowed for the best flow within the OEM gaskets footprint and has 1/2" NPT water bypass port. The domestic cap bung has a 1/8" NPT port and the import version has a 1/16" NPT for connection to an overflow. The domestic cap bung has a 1/8" NPT port and the import version has a 1/16" NPT for connection to an overflow. The domestic version uses any early model (late 70's Chevy C10 Pickup w/ 454) cap and the import version uses early model Honda (88'-91' Civic/ CRX and 90'-93' Integra) cap.
NOTE: Made to Order - Contact for ETA - The intake cam sensor must be swapped to the version that points up in order to clear the tank. If you are interested in a specific design that varies from this, please email us at email@example.com. If using AN lines we also recommend designing the upper radiator hose so that there is droop/ give so the engines movement and does not push/ pull on the radiator and fatigue any parts. The billet neck has a 1/2" NPT water bypass port and the hardware kit includes a hose fitting and a plug in the event you don't plan on connecting a bypass hose. The tank is welded so that it sits level when bolted to an engine leaned back 15° (exhaust side) for the traditional option and leaned forward 8° (intake side) for the gangster lean mount option.
