TracTuff RBB/ RBC Billet Water Neck w/ Swirl Tank - Sidewinder
Sidewinder turbo friendly version of the popular RBC/ RBB swirl tank.
The swirl tank starts with a beautifully machined 6061-T6 flange that incorporates the largest port possible within the OEM gaskets footprint and incorporates 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 wastegate feeds, and radiator cap bung types.
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 email@example.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 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) for the traditional option and leaned forward 8° (intake side) for the gangster lean mount option.
