TracTuff J Series Swirl Pot

TracTuff J Series Swirl Pot


So you own an EG, EK, or DC2 and you've swapped in a J Series... almost everything is right where you want it! Everything except for that MONSTROSITY of a water neck starring back at you. Our J Series billet water neck flanges do what no others do, hold the water cross-over tube, and is the best looking product to boot!!

The J Series billet water neck flanges were designed to be the premiere water neck solution on the market. The flanges can be used as is or used to fabricate pretty much anything you can dream up. The product represented here is just one concept. In time... I'm sure there will be more. The combo shown is one of two versions of swirl tanks available. Both tank inlets enter in the same direction, as high as possible, and exit in the same direction, as low as possible. This sure to be the highest point in your cooling system. 

Options are abundant but if you dont see something specific... email me. That's how this became a reality. I can add an ECT bung pretty much anywhere you want, a traditional hose barb connection for a heater core, and/ or accessory ports for aftermarket gauges. The product pictured also has a Wiggins clamp that allows the product to fit engines that have had material removed from block and/ or cylinder head(s). This is absolutely necessary because the cylinder heads move inward on V motors and that changes the location of the bolts that hold the water necks! 

Flanges, tank end caps and radiator cap bung are all machined from US milled 6061 aluminum. The rear flange incorporates an o-ring grove while the front retains the OEM gasket. The water cross-over tube mount is machined to accept the OEM o-ring on the back-side and converts to a -16 ORB port on the front-side. 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 If you have questions related to the configuration options... PLEASE visit the FAQ page. If you are 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.

Accessory Notes: 

ECT Sensor Bung -  Can be located in the tube coming from the rear cylinder head to the tank or in the actual tank. I suggest the tank so you get a blended temp for both cylinder heads, however... this will require the harness to be lengthened.

Heater Core Connection - Can be located in the tube coming from the rear cylinder head to the tank (in the bend but facing the firewall) or on the actual tank. Locating the connection in the tank will require you to use bulk hose and route the line.

Water Bypass Connection - Only used on systems that are going to incorporate a thermostat. Purchase of our inline thermostat will be required.
