My most recommended version!! This version is similar to the V1SF but has been moved back to the rear of the cylinder head. In doing so... many things are improved on. The inlet is allowed to be moved up, the outlet is further from the radiator, allowing for more hose to be used... reducing bad hose routing, and the support bracket is substantial!
The swirl pot starts with a beautifully machined 6061-T6 flange that incorporates the largest port possible within the OEM gaskets footprint, a 1/2" NPT water bypass port, and machined o-ring groove for the OEM gasket. You can choose to have a 1/8" NPT sensor port added directly to the top of the neck (near the logo) or the side (under the outlet) as well as choose from a number of accessory bung options on the tank. I prefer this version if you have the space, because the outlet is the furthest back it can be... completely eliminating the stress of engine movement through the hose. If the product is being used in a harsh environment, I recommend you add the plinth option to help spread the load/ weight and vibration on the bracket. The outlet itself 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 info@vk-garage.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. 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 has a 1/2" NPT water bypass port and the hardware kit includes a 5/8" hose fitting, a plug, 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) for the traditional option and leaned forward 8° (intake side) for the gangster lean mount option.
