TracTuff P72 Billet Water Neck w/ Swirl Tank

TracTuff P72 Billet Water Neck w/ Swirl Tank

$279.95

Okay B18C1 engine owners... this is the pennical of our water neck offerings! The proven swirl tank.

It all starts with our beautifully machined flange that incorporates a 3D tapered entry port for a seamless transition to the tubing that is routed to the tank. The backside of the flange has an o-ring grove for a positive seal without the hassle of Hondabond. The tank placement clears the distributor, VTEC solenoid, and the outlet still exits similarly to the original location; customers have actually reported that a trimmed GSR upper hose still works! 

1. Billet water neck with bead rolled 1-1/4" aluminum tube so you can attach your OEM rubber/ silicone hose - Not Shown

2. Billet water neck with 1-3/8" aluminum tube for a seamless transition to our -16 male bung - Shown

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 (mid 70's through late 80's Chevy) 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 sales@tractuff.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 tank is welded so that it sits level when bolted to an engine with a 5.5° lean forward (exhaust side).
