TracTuff RBB/ RBC Billet Water Neck w/ Swirl Tank & Overflow

TracTuff RBB/ RBC Billet Water Neck w/ Swirl Tank & Overflow

$599.95

A version of my RBB/RBC 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. Also, the original heater port on this flange cannot be used due to the configuration, a hose barb or AN bung can be added to the exposed side of the swirl tank on request. 


Our billet water neck has the largest port allowed for the best flow within the OEM gaskets footprint and has 1/2" NPT heater 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 version uses any early model (mid 70's through late 80's Chevy) cap and the import version uses early model Honda (88'-91' Civic/ CRX and 90'-93' Integra) cap. 


NOTE: Made to Order... usually a 2-3 day lead time - 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 sales@tractuff.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. Tank is welded so that it sits level when bolted to an engine with a 15° lean back (exhaust side).




1/1/19 Update: Due to the additional weight and stress placed on the brackets and braces, a plinth will be added at each location to distribute the load and increase strength.
