TracTuff PRB/ PRC Billet Water Neck w/ Swirl Tank V1SF

$349.95

The OG! This design was my very first. The tank sits just in front of the intake camshaft sensor and now has an added brace.


Our billet water neck incorporates an OEM o-ring grove on the mating surface and a 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 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. 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 lean option.


1/1/19 Update: Due to the stress placed on the brackets/ braces, a plinth can be added to distribute the load and increase strength.
