TracTuff PRB/ PRC Billet Water Neck w/ Fill Pot - RWD


Hey! Something new for all you rear wheel drive k swappers!! This fill pot is the ABSOLUTE tightest package I can make. I have crammed a 3.00" body into a space that does not extend beyond the camshaft sensor, making great use of wasted space and ensuring you are adding coolant to the highest point in the system. Available for the Skunk2 Ultra Street or Ultra Race intake manifold. 

The swirl pot starts with a beautifully machined 6061-T6 flange that incorporates the largest port possible within the OEM gaskets footprint and machined o-ring groove for the OEM gasket. The product shown uses the thinnest version of billet water neck for the PRB/ PRC style cylinder head; critical to making the product work in this limited space! Our other PRB/ PRC style flange can be used if water bypass is needed or you can choose to have a bypass port added elsewhere on the tank, such as the -10 male flare (shown). If tank to firewall space is not critical, choose the street style water neck flange that retains the original water bypass position. The Additional hose barb connection (shown) may not be necessary for you but it is an option.

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. 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 billet neck hardware kit includes two stainless M6 socket head bolts and a Genuine Honda gasket. The tank is welded so that it sits level when bolted to an engine leaned back 15° (OEM position). If your engine sits at a different angle, it is your responsibility to communicate that after the purchase has been made. Depending on your fuel line routing, this may require you to make changes.
