TracTuff PRB/ PRC Billet Water Neck w/ Swirl Tank V1SR

$349.95

My most recommended version!! This piece has simply been moved back, from the original position, to the rear of the cylinder head. In doing so... many things are improved on. The inlet is allowed to be moved up on the tank, the outlet allows for more hose to be used and reduces bad hose routing, and the support bracket is more substantial!


All billet parts are CNC machined from US milled 6061 aluminum. 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 - 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 billet neck has a 1/2" NPT port on the bottom side so you can choose to reconnect the factory water bypass hose (hose fitting option) or you can delete it (plug option), I recommend you keep it but its entirely up to you! Tank is welded so that it sits level when bolted to an engine with a 15° lean backwards (exhaust side).


1/1/19 Update: Due to the stress placed on the brace a plinth can be added to the bracket to help distribute the load and increase strength.
