TracTuff PRB/ PRC Swirl Pot – V1SR

Description

My most recommended version for the K20A, K20A2, K20A3, K20Z1, and K24A1 cylinder head.

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 begins with a beautifully machined flange that has been CNC-machined from US-milled 6061-T6 aluminum. The flange is machined with a -8 ORB water bypass port and an OEM o-ring groove. 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 can be clocked to your needs and configured for either standard hose (1.25″ OD) or -16 male flare.

NOTE: 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 engine’s movement 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 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). 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.
