TracTuff PRB/ PRC Swirl Pot - V1SF
The OG! This was my very first design for the for the K20A, K20A2, K20A3, K20Z1 and K24A1 cylinder heads.
I prefer this version if you have the space, because the outlet is far enough back to make hose routing a little less stressful on you as well as the product. 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 as well as help fight some of the tugging force from bad upper hose routing. The outlet itself can be configured for standard hose (1.25" OD) or -16 male flare.
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. 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. The intake cam sensor must be swapped out for the angled version found on the K24's.
