TracTuff PR3 Swirl Pot -V2

Description

The swirl pot is the top choice for PR3 (B16A/B16B/B18C/B18C5) cylinder head cooling system upgrades! Best solution for systems with tucked radiators, a radiator without a cap bung, or situations where you want a higher fill point to aid in burping the sometimes troublesome cooling system.

The swirl pot starts with a CNC-machined flange, milled from US 6061 material. The flange incorporates an o-ring groove, so you no longer need to mess with Hondabond. The V2 PR3 swirl pot clears the VTEC spool valve assembly but does not clear the heater nipple on the cylinder head, nor does it work a distributor. If you are using an EPM in the distributor’s place, please communicate the distance it protrudes from the mounting surface; if no information is provided after the purchase, I will assume a cam plug is being used.

NOTE: Due to tank placement, the heater port on the cylinder head must be plugged. 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 with some droop/give so the engine’s movement does not push/pull on the radiator and fatigue any parts.

The swirl pot includes two M6 socket head bolts and an o-ring. The tank is welded so that it sits level when bolted to an engine leaned forward 5.5° (exhaust side).
