TracTuff PRB/ PRC Swirl Pot - V1SR
My most recommended version for the K20A, K20A2, K20A3, K20Z1 and K24A1 cylinder heads.
This version is similar to the V1SF but has been moved back to the rear of the cylinder head and in doing so, many things are improved. The inlet is allowed to be moved up on the pot, the outlet is further from the radiator which allows for a longer hose to be used, and the support bracket is more stout!
The swirl pot starts with a beautifully machined billet 6061-T6 flange which incorporates the largest passage possible within the OEM gaskets footprint, a -8 ORB water bypass port, and a machined o-ring groove for the OEM gasket. You can choose to add a sensor port directly to the top of the flange (near the logo) or the side of the flange (under the outlet). 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 email@example.com. The cap bung has a 1/16" NPT port for connection to the overflow and uses early model Honda radiator caps, such as an 88'-91' Civic/ CRX or 90'-93' Integra. If you are using AN line, 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 hardware kit includes a -8 ORB to 11/16" water bypass hose fitting, a stainless hose clamp, two stainless M6 socket head bolts, and a Genuine Honda gasket. If you are looking for a version that sits properly on an engine leaned forward 8° (Hasport Gangster Lean mount position) take a look at the V1SR Lean version.
