TracTuff PR3 Swirl Pot
The swirl pot is the top choice for PR3 (B16A/ B16B/ B18C/ B18C5) cylinder head cooling system upgrades! Best solution for systems that have tucked radiators, a radiator without a cap bung or for situations where you want a higher fill point to aid in burping the sometimes troublesome cooling system.
The swirl pot starts with a beautifully machined 6061-T6 flange that incorporates incorporates a 3D tapered entry port for a seamless transition to 1.25" tubing. The backside of the flange has an o-ring grove for a positive seal without the hassle of Hondabond. The tanks inlet tube is now one piece, custom bent to avoid the distributor, heater line port, and VTEC spool valve assembly, eliminating the welding of two separate tubes. The tank is braced to the cylinder head for added support. The outlet can be configured for standard hose (1.25" OD) or -16 male flare.
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 you have questions related to the configuration or options... PLEASE visit the WHATS WHAT or FAQ page. The cap bung has a 1/16" NPT port for connection to an overflow and uses early model Honda radiator caps; such as an 88'-91' Civic/ CRX or 90'-93' Integra. If you are using AN lines, I 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 swirl pot includes two stainless M6 socket head bolts and an o-ring. The tank is welded so that it sits level when bolted to an engine leaned forward 5.5° (exhaust side).
