TracTuff RBB/ RBC Billet Water Neck w/ Swirl Tank - RWD
Something new for all your rear wheel drive k swappers!! This swirl tank takes advantage of wasted space in the small pocket between the Skunk2 Ultra Street or Ultra Race intake manifold and firewall and offers a premier solution for bleeding the cooling system; which would otherwise be a real project.
The swirl tank starts with a beautifully machined flange that incorporates the largest port possible within the OEM gaskets footprint as well as a 1/2" NPT heater port. You can chose from a list of options to make the product as unique as your project; including outlet position, accessory ports for aftermarket sensors and/ or turbo and waste gate feeds, and radiator cap bung types. Please note that the outlet position in this example was requested by the customer, you can select the position.
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 with a 15° lean backwards (exhaust side).
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.
