TracTuff PRB/ PRC Swirl Pot - V4
This most recent version is basically a flipped V2 swirl pot for K20A, K20A2, K20A3, K20Z1 and K24A1 cylinder heads. Moves the pot back a few inches as a result of the inlet and outlet tubes to the front of the cylinder instead of the back.
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.
The hardware kit includes two M6 stainless steel socket head bolts, a water bypass hose fitting, and a Genuine Honda gasket. The swirl pot is welded so that it sits level when bolted to an engine leaned back 15° (OEM option) or leaned forward 8° (Gangster Lean engine mount 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 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.
