The S2000 Remote Mount Swirl Pot is my answer to requests to an F20C/ F22C billet water neck and/ or filler neck.
I've been reluctant to make a billet version of the factory upper water neck; I simply don't see the value in it, only allow for products to be fabricated or simply be used to run AN lines. The factory water neck features make it a challenge to machine, therefore expensive, and you wont even be able to see it.
The remote mount swirl pot is a better way! The swirl pot is located in the path of the factory upper radiator hose... all you have to do is cut the hose and attach it. You can either choose standard hose on the outlet and continue to run the factory hose or you can opt for an AN connection and run AN lines from this point on!
The swirl pot is higher than the cylinder head outlet, making this the highest point in the cooling system without cluttering up an area you might need. The product shown is part of my more serious race products that use a header tank to handle trapped air and coolant expansion but I know that in a short time, a customer will come along and commission a build that has a radiator cap bung (then I'll update the picture) to make this a simpler design that uses a traditional overflow.
NOTE: Made to Order - Contact for ETA - If you are interested in a non-lean version or a specific design that varies from this, please email us at email@example.com or If you have questions related to the configuration or options. 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.
