TracTuff RBB/ RBC Billet Water Neck w/ Swirl Tank - RWD w/ ITB's
Something new for all your rear wheel drive k swappers!! This swirl tank takes advantage of wasted space and offers a premier solution for bleeding the cooling system; which would otherwise be a real project.
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. 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 firstname.lastname@example.org. 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 heater port and the hardware kit includes a 90° hose fitting and a plug in the event you don't plan on connecting a heater hose. The tank is welded so that it sits level when bolted to an engine leaned back 15° (exhaust side).
1/1/19 Update: Due to the stress placed on the braces, from poorly plumbed upper radiator hoses, a plinth can be added to the bracket to help distribute the load and increase strength.
