PHR - 20AN Upper Waterneck, Non-Bypass for 2JZ-GTE

Non Bypass

This is a Non-Bypass waterneck, meaning that it does not have provisions for radiator bypass tube (that little tube between the waterneck and the water pump). These waternecks are good for those not running the factory water pump. Electric water pumps negate the need for bypassing the radiator because flow can be controlled by the waterpump during warmup.

Turbo Clearance

This neck creates a LOT of room for even the largest turbochargers. These will work with virtually any turbocharger you can bolt to the side of the 2jzgte.

It hugs the timing area as close as possible. The protrusion near the bolts is kept as narrow as possible without sacrificing any flow.

-20AN Outlet

The -20AN Fitting is perfect for attaching -20AN radiator hose for the ultimate in cooling performance and reliability.
